Recurrence defined as no change in or worsening of preoperative stage of posterior wall prolapse. The mesh is attached to the posterior vaginal wall with a series of sutures and to the anterior longitudinal ligament of the sacrum in a tension-free fashion. Through a perineal body or vaginal approach, deep dissection into the rectovaginal space can be facilitated by injection with dilute epinephrine solution. Dissection is continued to the point of apical attachment (usually the sacrospinous ligament). An anatomic cure rate ranging from 54% to 92% reflects the variation in type of mesh, method of placement, and definition of cure. Tension-free Vaginal Mesh Kit Procedures Compensatory procedures, such as the abdominal sacrocolpopexy, enjoy the stasis of the gold standard surgical repair of pelvic organ prolapse. The majority of the kits use the bilateral apical anchoring points in the sacrospinous ligament. Typically, the rectovaginal space is injected with a dilute vasocontrictive agent or normal saline. An incision is made through the entire vaginal wall, most commonly in a vertical fashion. The rectovaginal space is dissected vertically from the perineal body to the ischial spines and sacrospinous ligaments, then horizontally from sidewall to sidewall. Various methods are employed to suspend the mesh without tension to the sacrospinous ligament. The mesh is additionally attached with sutures to the vaginal apex or cervix near the internal os and to the perineal body. Tacking sutures to the vaginal sidewall may be performed in an attempt to prevent the mesh from bunching up. While setting the mesh in place, the surgeon must realize that shrinkage decreasing the surface area of the mesh of up to 20% may occur. Shrinkage of the mesh may cause complications such as vaginal pain, which worsens with movement, focal tenderness over contracted portions of the mesh (particularly mesh arms), dyspareunia, or recurrence of prolapse. Pre- and postsurgical treatment of the vaginal epithelium with topical estrogen is advocated to decrease the incidence of mesh erosion. The most commonly reported complication with mesh-augmented procedures is erosion. The shortterm erosion rate using the mesh kit in the anterior vaginal wall is up to 15. Erosion is related to the mesh properties including the type of mesh and its surface area, operative technique including the length and depth of placement of the vaginal incision, the presence of infection, and the health of the woman receiving the mesh. Mesh with a pore size greater than 75 m allows leukocytes and macrophages to patrol the mesh for bacteria. Some investigators have found that a concomitant hysterectomy or trachelectomy increases the length of the vaginal incision and increases the risk of vaginal erosion by eight- to ninefold. Smoking, with many deleterious effects on the health of vaginal tissue and healing, is a risk factor for mesh erosion in both transabdominal and transvaginal procedures. For this table, the total (58) and posterior (28 procedures) were extracted from the retrospective evaluation (20 anterior Prolift procedures were excluded). For this analysis, the Apogee portion of the study was extracted from the retrospective evaluation of Apogee (48) and Perigee (72 procedures). Thirty-six women underwent anterior only Prolift placement and were excluded in number, cure, and erosion rate (all erosions were in the anterior compartment). The percentage of de novo dyspareunia included all patients (anterior 36; total 8; posterior 23) follow up (F/U) is median. Cure of posterior only patients was available; therefore, these patients were included in the table. Late erosions were significantly more common in women who were sexually active compared to those who were not (17. Food and Drug Administration notification was posted in 2008, and updated in 2011, encouraged extensive preoperative counseling for transvaginal mesh procedures. Preoperatively, women should be informed that the implantation of mesh is permanent, complications associated with mesh placement may require additional surgery that may or may not correct the complication, and that there is potential for serious complications that may affect quality of life including pain, dyspareunia, scarring, or narrowing of the vagina. They may become symptomatic and require surgical drainage days after the original procedure. The tension-free vaginal mesh procedures have also been associated with vaginal pain, defecatory pain, and dyspareunia. Banding of the mesh may contribute to pain, therefore, Chapter 13 Posterior Vaginal Wall Prolapse 239 release of the sling arm at their point of attachment to the levator plate may help relax the vaginal wall. The prolapse transvaginal mesh kit procedures have received widespread acceptance by the gynecologic community of surgeons. The success of the midurethral slings should not be directly translated to the tensionfree vaginal mesh kit procedures for prolapse. The first-generation total mesh kits include long blind passes of needles through the ischiorectal fossa. Importantly, the possible long-term surgical complications are yet to be determined. The management of complications is potentially more difficult with the mesh in place. The surgeon must weigh the possible gain in anatomic efficacy, efficiency of the procedure, attractiveness of a vaginal approach, and potential durability (yet to be demonstrated) against the potential morbidity associated with mesh erosion, pain, and potential, unforeseen complications. Therefore, obstructed defecation that is caused by a large rectal volume may be improved with the transperineal repair. Beginning 1 cm above the dentate line, the anterior rectal mucosa is opened in the midline along the extent of the rectocele.

Muscles of Forearm the tendons of the forearm muscles pass through the distal part of the forearm and continue into the wrist thyroid nodules greater than 1 cm safe levothroid 100 mcg, hand, and fingers. The flexors and pronators of the forearm are in the anterior compartment and are served mainly by the median nerve; the one and a half exceptions are innervated by the ulnar nerve. The distal attachment of the deltoid can be palpated on the lateral surface of the humerus. The triceps tendon may be felt as it descends along the posterior aspect of the arm to the olecranon. Medial and lateral bicipital grooves separate the bulges formed by the biceps and triceps. The cephalic vein runs superiorly in the lateral bicipital groove, and the basilic vein ascends in the medial bicipital groove. The biceps tendon can be palpated in the cubital fossa, immediately lateral to the midline. The proximal part of the bicipital aponeurosis can be palpated where it passes obliquely over the brachial artery and median nerve. The brachial artery may be felt pulsating deep to the medial border of the biceps. These muscles are all attached proximally by a common flexor tendon to the medial epicondyle of the humerus, the common flexor origin. The five superficial and intermediate muscles cross the elbow joint; the three deep muscles do not. Therefore, the brachioradialis is a major exception to the generalization that the radial nerve supplies only extensor muscles and that all flexors are in the anterior compartment. Pronator quadratus Distal quarter of anterior surface of ulna a the spinal cord segmental innervation is indicated. When the wrist is flexed at the same time that the metacarpophalangeal and interphalangeal joints are flexed, the long flexor muscles of the fingers are operating over a shortened distance between attachments, and the action resulting from their contraction is consequently weaker. Extending the wrist increases their operating distance, and thus their contraction is more efficient in producing a strong grip. Tendons of the long flexors of the digits pass through the distal part of the forearm, wrist, and palm and continue to the medial four fingers. It initiates pronation and is assisted by the pronator teres when more speed and power are needed. The pronator quadratus also helps the interosseous membrane hold the radius and ulna together, particularly when upward thrusts are transmitted through the wrist. The extensor tendons are held in place in the wrist region by the extensor retinaculum, which prevents bowstringing of the tendons when the hand is extended at the wrist joint. The extensor indicis tendon joins the tendons of extensor digitorum to pass deep to the extensor retinaculum through the tendinous sheath of extensor digitorum and extensor indicis (common extensor synovial sheath). On the dorsum of the hand, the tendons of extensor digitorum spread out as they run toward the fingers. Transverse section through distal end of radius and ulna to show extensor tendons in their synovial sheaths. Consequently, normally no finger can remain fully flexed as the other ones are fully extended. Each extensor expansion (dorsal expansion or "hood") is a triangular tendinous aponeurosis that wraps around the dorsum and sides of a head of the metacarpal and base of the proximal phalanx. The visor-like "hood" of the extensor expansion over the head of the metacarpal is anchored on each side to the palmar ligament (a thickened portion of the fibrous layer of the joint capsule of the metacarpophalangeal joints). In forming the extensor expansion, each extensor digitorum tendon divides into a median band, which passes to the base of the middle phalanx, and two lateral bands, which pass to the base of the distal phalanx. During flexion of the distal interphalangeal joint, the retinacular ligament becomes taut. The taut retinacular ligament pulls the proximal interphalangeal joint into flexion. Similarly, on extending the proximal joint, the distal joint is pulled by the retinacular ligament into nearly complete extension. Although the radial nerve appears in the cubital region, it soon enters the posterior compartment of the forearm. The median nerve is the principal nerve of the anterior compartment of the forearm. Articular and muscular branches and a palmar cutaneous branch are also derived from the median nerve. The branches of the ulnar nerve in the forearm (articular, muscular, and palmar and dorsal cutaneous branches) are described in Table 6. The deep branch of radial nerve arises anterior to the lateral epicondyle and pierces the supinator. The superficial branch of the radial nerve (sensory or cutaneous) emerges in the distal part of the forearm and crosses the roof of the anatomical snuff box. It is distributed to skin on the dorsum of the hand and to a number of joints in the hand. When the brachioradialis is pulled laterally, the entire length of the artery is visible until the distal part of the forearm. There are superficial and deep veins in the forearm: superficial veins ascend in the subcutaneous tissue; deep veins accompany the deep arteries. These synovial cysts are close to and often communicate with the synovial sheaths. A cystic swelling of the common flexor synovial sheath on the anterior aspect of the wrist can enlarge enough to produce compression of the median nerve by narrowing the carpal tunnel (carpal tunnel syndrome). Elbow Tendinitis or Lateral Epicondylitis Elbow tendinitis (tennis elbow) is a painful musculoskeletal condition that may follow repetitive use of the superficial extensor muscles of the forearm.

The posterior bending is produced by the posterior displacement and tilt of the distal fragment of the radius thyroid symptoms gaining weight levothroid 50 mcg with visa. Pain occurs primarily on the lateral side of the wrist, especially during dorsiflexion and abduction of the hand. Initial radiographs of the wrist may not reveal a fracture, but radiographs taken 10 to 14 days later may reveal a fracture because bone resorption has occurred. Owing to the poor blood supply to the proximal part of the scaphoid, union of the fractured parts may take several months. Avascular necrosis of the proximal fragment of the scaphoid (pathological death of bone resulting from poor blood supply) may occur and produce degenerative joint disease of the wrist. Fracture of the hamate may result in nonunion of the fractured bony parts because of the traction produced by the attached muscles. Because the ulnar nerve is close to the hook of the hamate, the nerve may be injured by this fracture, causing decreased grip strength of the hand. Severe crushing injuries of the hand may produce multiple metacarpal fractures, resulting in instability of the hand. A fracture of a distal phalanx is usually comminuted, and a painful hematoma (collection of blood) develops. Fractures of the proximal and middle phalanges are usually the result of crushing or hyperextension injuries. Between the elevated sternal ends of the clavicles is the jugular notch (suprasternal notch). The acromial end of the clavicle often rises higher than the acromion, forming a palpable elevation at the acromioclavicular joint. Inferior to the acromion, the deltoid muscle forms the rounded curve of the shoulder. The crest of the spine of the scapula is subcutaneous throughout and can be easily palpated. The lateral border of scapula is not easily palpated because it is covered by the teres major and minor muscles. When the arm is abducted, the greater tubercle is pulled beneath the acromion and is no longer palpable. The lesser tubercle of the humerus may be felt with difficulty by deep palpation through the anterior deltoid, approximately 1 cm laterally and slightly inferior to the tip of the coracoid process. The location of the intertubercular sulcus or groove, between the greater and the lesser tubercles, is identifiable during flexion and extension of the elbow joint by palpating in an upward direction along the tendon of the long head of the biceps brachii as it moves through the intertubercular sulcus. The shaft of humerus may be felt with varying distinctness through the muscles surrounding it. The medial and lateral epicondyles of the humerus are palpated on the medial and lateral aspects of the elbow region. When the elbow joint is extended, observe that the tip of the olecranon and the humeral epicondyles lie in a straight line. When the elbow is flexed, the olecranon forms the apex of an approximately equilateral triangle, of which the epicondyles form the angles at its base. The head of radius can be palpated and felt to rotate in the depression on the posterolateral aspect of the extended elbow, just distal to the lateral epicondyle of the humerus. The head of ulna forms a rounded subcutaneous prominence that can be easily seen and palpated on the medial side of the dorsal aspect of the wrist. The pointed subcutaneous ulnar styloid process may be felt slightly distal to the ulnar head when the hand is supinated. The hook of hamate can be palpated on deep pressure over the medial side of the palm, about 2 cm distal and lateral to the pisiform. The tubercles of the scaphoid and trapezium can be palpated at the base and medial aspect of the thenar eminence (ball of thumb) when the hand is extended. The heads of the metacarpals form the knuckles; the 3rd metacarpal head is the most prominent. The knuckles of the fingers are formed by the heads of the proximal and middle phalanges. When measuring upper limb length, or segments of it, the acromial angle, lateral epicondyle of the humerus, styloid process of the radius, and tip of the 3rd finger are most commonly used as measuring points, with the limb relaxed (dangling) but with the palm directed anteriorly. If no structure (muscle or tendon, for example) intervenes between the skin and the bone, the deep fascia usually attaches to bone. Fascia of Upper Limb the pectoral fascia invests the pectoralis major and is continuous inferiorly with the fascia of the anterior abdominal wall. Deep to the pectoral fascia and the pectoralis major, another fascial layer, the clavipectoral fascia, descends from the clavicle, enclosing the subclavius and then the pectoralis minor, becoming continuous inferiorly with the axillary fascia. The part of the clavipectoral fascia between the pectoralis minor and the subclavius, the costocoracoid membrane, is pierced by the lateral pectoral nerve, which primarily supplies the pectoralis major. The scapulohumeral muscles that cover the scapula and form the bulk of the shoulder are also ensheathed by deep fascia. The muscles that cover the anterior and posterior surfaces of the scapula are covered superficially by strong and opaque deep fascia, which is attached to the margins of the scapula. This arrangement creates osseofibrous subscapular, supraspinous, and infraspinous compartments.

Some advocate not placing mesh beyond 3 cm from the hymeneal ring on the posterior wall to prevent erosions in this area. It may also be beneficial to narrow the distal portion of the mesh to avoid folding and mesh burden in the distal posterior compartment. The proximal part of the mesh is appropriately trimmed and secured to the cervix or anterior and posterior walls of the vagina at the apex with permanent or delayed absorbable sutures. Once the mesh has been appropriately sized and secured, the mesh arms are retrieved by using the retrieval sutures previously introduced. It is critical that the surgeon once again ensures integrity of the rectal wall at this point. One finger in the rectum and one in the rectovaginal and pararectal spaces can be used to follow the entire path of the mesh from superior to inferior and across the midline. At this time the distal portion of the mesh can be secured to the apex of the perineal body with several interrupted delayed absorbable sutures and the posterior vaginal wall is reapproximated with 2-0 or 3-0 absorbable suture. The mesh should be positioned without tension and it should allow adequate distention of the rectum as it occurs physiologically during stool storage. Anterior Access to the Sacrospinous Ligament With some of the more recently described "trocarless" mesh procedures, the sacrospinous ligaments are accessed bilaterally via the paravesical space. Proposed advantages are to improve the vaginal axis and treat both anterior and apical defects through a single incision while avoiding blind passage of needles, trocars, and mesh through the ischioanal fossa. Limited data exist at this time on efficacy and complications of these procedures. The paravesical space is entered by lateral dissection from the vesicovaginal space. The recommended fixation point on the sacrospinous ligament remains 2 to 3 cm medial to the ischial spine. Routine postoperative care is indicated with voiding trial performed on postoperative day one or two. Lower extremity neurologic examination to screen for neuropathy should be performed prior to discharge.

By reviewing the bladder diary with the clinician thyroid gland adenoma levothroid 200 mcg purchase otc, patients can identify times when they are at increased risk of an incontinence episode and activities that can trigger incontinence. In particular, identifying the circumstances that precipitate incontinence episodes helps to prepare patients to implement the continence skills they are about to learn. This includes an explanation of the anatomy of the bladder and pelvic floor, how they function, and the causes and mechanisms of urinary incontinence and other lower urinary tract symptoms. It is essential for women to understand that their behavioral program is based on changing their habits and learning new skills, and that improvement is often gradual. Further, understanding that their results will depend on active participation and daily practice facilitates adherence and realistic expectations about therapeutic outcomes. Most women with urinary symptoms believe that they have no control over their condition. As they implement the components of behavioral treatment, they are often empowered to discover increasing control over their symptoms and improvements in their quality of life. Behavioral Treatment for Stress Incontinence Pelvic Floor Muscle Training and Exercise Pelvic floor muscle training and exercise is a cornerstone of behavioral treatment for both urinary and fecal incontinence. It was originally designed to teach patients how to control and exercise periurethral muscles with the goal of strengthening the muscles and reducing stress incontinence. It was first popularized by Kegel, a gynecologist who proposed that stress incontinence was due to a lack of awareness of function and coordination of pelvic floor muscles,11 and who also demonstrated that women could reduce their stress incontinence through pelvic floor muscle training and exercise. Teaching Pelvic Floor Muscle Control the first step in training is to assist the woman to identify the pelvic floor muscles and to contract and relax them selectively, without increasing pressure on the bladder or pelvic floor. Confirming that patients have identified and isolated the correct muscles is essential and often overlooked. Failure to find the pelvic floor muscles or to exercise them correctly is perhaps the most common reason for failure with this treatment modality. While it is easy for a clinician to give a patient a pamphlet or brief verbal instructions to "lift the pelvic floor," to hold back the passage of flatus, or to interrupt the urinary stream, this approach does not ensure that the correct muscles are used when she begins her exercises at home. Several techniques can be used to help patients learn to exercise correctly, including verbal feedback based on vaginal or anal palpation,13-17 biofeedback,14-24 or electrical stimulation. Contracting certain abdominal muscles can be counterproductive when it increases pressure on the bladder, bowel, or pelvic floor. Therefore, it is important to observe for this Valsalva maneuver and to help patients to exercise pelvic floor muscles selectively while relaxing these abdominal muscles. Instructing the patient not to hold her breath or to count out loud can be helpful to avoid the Valsalva maneuver. This approach remains controversial, however, and a recent review article noted an absence of evidence for this type of training. The purpose of daily exercise is not only to increase muscle strength but also to enhance motor skills through practice. Pelvic floor muscle exercise regimens vary considerably in frequency and intensity, and the optimal exercise regimen has not been determined. However, good results have been achieved in several trials using 45 to 50 paired contractions and relaxations per day. Exercising while in the prone position is often recommended at first, because it is the least challenging. However, it is important for patients to progress to sitting or standing positions with time, so that they become comfortable and skilled using their muscles to avoid incontinence in any position. Exercise regimens should be individualized so that patients begin with a comfortable and achievable duration and gradually progress to ten seconds. Each exercise consists of muscle contraction followed by a period of relaxation using a 1:1 or 1:2 ratio. Although exercise alone can improve urethral pressure and structural support and reduce incontinence,30 in recent years, more emphasis has been placed on teaching patients to contract the pelvic floor muscles to occlude the urethra during physical activities that cause stress incontinence. As with any new skill, this requires vigilance and a conscious effort initially on the part of the patient. Stress leakage happens when the pressure pushing urine out is higher than the pressure holding the urine in, such as during coughing, sneezing, bending over, lifting, or getting up from a chair. Look at your bladder diary and note what physical activities have caused you to leak urine: Coughing If you forget to tighten your muscles and urine leaks out, go ahead and squeeze your muscles right then. It would not prevent that leakage, but it will help associate tightening your muscles with that activity. Chapter 21 Behavioral Treatment for Pelvic Floor Dysfunction 375 Table 21-1 Behavioral Treatment Program for Stress Incontinence Visit 1 1. Patients who cannot contract their pelvic floor muscles at all should be referred for biofeedback 2. Prescribe a home program of exercise, for example, contract 2 s, relax 2 s with 15 repetitions, 3 sessions per day 3. Teach stress strategy, that is, squeeze pelvic floor muscles just prior to and during sneezing, coughing, lifting 3. Home exercise prescription: advance contraction and relaxation times by 1 s per week until 10 s each; still 15 in a row; still 3 times per day 5. Review bladder diary, discuss any leakage, and recommend appropriate strategies for prevention. If mixed incontinence, teach urge suppression strategy (see Table 21-2, Visit 1) 2.

Injury to Tibial Nerve Injury to the tibial nerve is uncommon because of its protected position in the popliteal fossa; however kale thyroid symptoms buy levothroid line, the nerve may be injured by deep lacerations in the fossa. The plantar fascia holds parts of the foot together, helps protect the sole from injury, and passively supports the longitudinal arches of the foot. The plantar aponeurosis arises posteriorly from the calcaneus and distally divides into five bands that become continuous with the fibrous digital sheaths that enclose the flexor tendons that pass to the toes. Inferior to the heads of the metatarsals, the aponeurosis is reinforced by transverse fibers forming the superficial transverse metatarsal ligament. In the forefoot only, a fourth compartment, the interosseous compartment of the foot, contains the metatarsals, the dorsal and plantar interosseous muscles, and the deep plantar and metatarsal vessels. From the plantar aspect, muscles of the sole are arranged in four layers within four compartments. They basically resist forces that tend to reduce the longitudinal arch as weight is received at the heel (posterior end of the arch), and is then transferred to the ball of the foot and great toe (anterior end of the arch). Concurrently, they are also able to refine further the efforts of the long muscles, producing supination and pronation in enabling the platform of the foot to adjust to uneven ground. The muscles of the foot are of little importance individually because fine control of the individual toes is not important to most people. Rather than producing actual movement, they are most active in fixing the foot or in increasing the pressure applied against the ground by various aspects of the sole or toes to maintain balance. Despite its name, the adductor hallucis is probably most active during the push-off phase of stance in pulling the lateral four metatarsals toward the great toe, fixing the transverse arch of the foot, and resisting forces that would spread the metatarsal heads as weight and force are applied to the forefoot (Table 5. The dorsalis pedis artery (dorsal artery of foot), often a major source of blood supply to the forefoot, is the direct continuation of the anterior tibial artery. The dorsalis pedis artery begins midway between the malleoli (at the ankle joint) and runs anteromedially, deep to the inferior extensor retinaculum between the extensor hallucis longus and the extensor digitorum longus tendons on the dorsum of the foot. The tibial nerve divides posterior to the medial malleolus into the medial and lateral plantar nerves. The medial plantar nerve courses within the medial compartment of the sole between the first and the second muscle layers. Initially, the lateral plantar nerve runs laterally between the muscles of the first and second layers of plantar muscles. Their deep branches then pass medially between the muscles of the third and fourth layers. The medial and lateral plantar nerves are accompanied by the medial and lateral plantar arteries and veins. The sole of the foot has prolific blood supply from the posterior tibial artery, which divides deep to the flexor retinaculum. The terminal branches pass deep to the abductor hallucis as the medial and lateral plantar arteries, which accompany similarly named nerves. The medial plantar artery supplies the muscles of the great toe and the skin on the medial side of the sole and has digital branches that accompany digital branches of the medial plantar nerve. Initially, the lateral plantar artery and nerve course laterally between the muscles of the first and second layers of plantar muscles. As it crosses the foot, the deep plantar arch gives rise to four plantar metatarsal arteries; three perforating branches; and many branches to the skin, fascia, and muscles in the sole. The plantar digital arteries arise from the plantar metatarsal arteries near the base of the proximal phalanx, supplying adjacent digits. The deep veins consist of inter-anastomosing paired veins accompanying all the arteries internal to the deep fascia. The superficial veins are subcutaneous, are unaccompanied by arteries, and drain most of the blood from the foot. The deep lymphatic vessels from the foot also drain into the popliteal lymph nodes. Lymphatic vessels from them follow the femoral vessels to the deep inguinal lymph nodes. The movements of the lower limb during walking on a level surface may be divided into alternating swing and stance phases. The swing phase begins after push-off, when the toes leave the ground, and ends when the heel strikes the ground. The swing phase occupies approximately 40% of the walking cycle and the stance phase, 60%. Walking is a remarkably efficient activity, taking advantage of gravity and momentum so that a minimum of physical exertion is required. Lymphatic Drainage of Foot the lymphatics of the foot begin in the subcutaneous plexuses. The collecting vessels consist of superficial and deep lymphatic vessels, which follow the superficial veins and major vascular bundles, respectively. It causes pain on the plantar surface of the heel and on the medial aspect of the foot. Point tenderness is located at the proximal attachment of the plantar aponeurosis to the medial tubercle of the calcaneus and on the medial surface of this bone. The pain increases with passive extension of the great toe and may be further exacerbated by dorsiflexion of the ankle and/or weight bearing. A calcaneal spur (abnormal bony process) protruding from the medial tubercle has long been associated with plantar fasciitis and pain on the medial side of the foot when walking; however, many asymptomatic patients are found to have such spurs. Plantar Reflex the plantar reflex (L4, L5, S1, and S2 nerve roots) is a myotatic (deep tendon) reflex. The lateral aspect of the sole is stroked with a blunt object, such as a tongue depressor, beginning at the heel and crossing to the base of the great toe.

The azygos system exhibits much variation not only in its origin but also in its course juvenile thyroid symptoms discount levothroid, tributaries, anastomoses, and termination. The azygos vein ascends in the posterior mediastinum, passing close to the right sides of the bodies of the inferior eight thoracic vertebrae. In addition to the posterior intercostal veins, the azygos vein communicates with the vertebral venous plexuses that drain the back, vertebrae, and structures in the vertebral canal (see Chapter 4). The hemi-azygos vein ascends on the left side of the vertebral column, posterior to the thoracic aorta as far as T9. Here, it crosses to the right, posterior to the aorta, thoracic duct, and esophagus, and joins the azygos vein. Sometimes, the accessory hemi-azygos vein joins the hemi-azygos vein and drains with it into the azygos vein. There are several nodes posterior to the inferior part of the esophagus and more anterior and lateral to it. The posterior mediastinal lymph nodes receive lymph from the esophagus, the posterior aspect of the pericardium and diaphragm, and the middle posterior intercostal spaces. The thoracic sympathetic trunks are in continuity with the cervical and lumbar sympathetic trunks. The thoracic sympathetic trunks lie against the heads of the ribs in the superior part of the thorax, the costovertebral joints in the midthoracic level, and the sides of the vertebral bodies in the inferior part of the thorax. The lower thoracic splanchnic nerves, also known as greater, lesser, and least splanchnic nerves, are part of the abdominopelvic splanchnic nerves because they supply viscera inferior to the diaphragm. They consist of presynaptic fibers from the 5th to 12th paravertebral sympathetic ganglia, which pass through the diaphragm and synapse in prevertebral ganglia in the abdomen. Clinical Box Laceration of Thoracic Duct Because the thoracic duct is thin-walled and may be colorless, it may not be easily identified. Consequently, it is vulnerable to inadvertent injury during investigative and/or surgical procedures in the posterior mediastinum. Laceration of the thoracic duct results in chyle escaping into the thoracic cavity. Aneurysm of Ascending Aorta the distal part of the ascending aorta receives a strong thrust of blood when the left ventricle contracts. Because its wall is not yet reinforced by fibrous pericardium (the fibrous pericardium blends with the aortic adventitia at the beginning of the arch), an aneurysm (localized dilation) may develop. An aortic aneurysm is evident on a chest film (radiograph of the thorax) or a magnetic resonance angiogram as an enlarged area of the ascending aorta silhouette. Individuals with an aneurysm usually complain of chest pain that radiates to the back. The aneurysm may exert pressure on the trachea, esophagus, and recurrent laryngeal nerve, causing difficulty in breathing and swallowing. In some people, an accessory azygos vein parallels the main azygos vein on the right side. Consequently, any investigative procedure or disease process in the superior mediastinum may involve these nerves and affect the voice. Because the left recurrent laryngeal nerve hooks around the arch of the aorta and ascends between the trachea and the esophagus, it may be involved when there is a bronchial or esophageal carcinoma, enlargement of mediastinal lymph nodes, or an aneurysm of the arch of the aorta. In the latter condition, the nerve may be stretched by the dilated arch of the aorta. When the coarctation is inferior to this site (postductal coarctation), a good collateral circulation usually develops between the proximal and distal parts of the aorta through the intercostal and internal thoracic arteries. Arch of aorta Variations of Great Arteries the most superior part of the arch of the aorta is usually approximately 2. Sometimes, the arch curves over the root of the right lung and passes inferiorly on the right side, forming a right arch of the aorta. If the trachea is compressed enough to affect breathing, surgical division of the vascular ring may be needed. The usual pattern of branches of the arch of the aorta is present in approximately 65% of people. In approximately 27% of people, the left common carotid artery originates from the brachiocephalic trunk. Age Changes in Thymus the thymus is a prominent feature of the superior mediastinum during infancy and childhood. The thymus plays an important role in the development and maintenance of the immune system. By adulthood, it is usually replaced by adipose tissue and is often scarcely recognizable; however, it continues to produce T lymphocytes. Radiopaque dye has been injected into the left (A) and the right (B) coronary arteries. Superior vena cava Ascending aorta Right auricle Right coronary artery Right atrium Coronary (atrioventricular) sulcus 7. Right ventricle Inferior vena cava Left ventricle Anterior interventricular artery 11. The abdominal wall encloses the abdominal cavity, containing the peritoneal cavity and housing most of the organs (viscera) of the alimentary system and part of the urogenital system. The pelvic inlet (superior pelvic aperture) is the opening into the lesser pelvis.

Intraoperative the treatment can be performed as an outpatient case using local anesthesia thyroid blood test name proven 50 mcg levothroid. The injection must be slow, allowing for the perception of the formation of a small, elastic ball in the anal canal. The result of the treatment is a very rapid contraction of the collagenous tissue followed by wound healing. The consequent tightening of the anal canal may give satisfactory functional results. Although Secca does not preclude any further invasive treatments, scarring of the anal canal may render surgical procedures technically difficult. On deployment, there is a reduction in electrical impedance, indicating the proper contact of the electrode with the submucosal layer. Antibiotic prophylaxis (ciprofloxacin and metronidazole) is advisable and there is no need for bowel preparation. Patients can be positioned in the lithotomy position and local anesthesia is administered. After digital examination and anoscopy, the device is positioned under direct visualization of the anal canal. It is likely that sphincter muscles are prone to similar degenerative processes as other muscles. Several aspects of sphincter dysfunction may represent targets for regenerative therapy. Three main strategies can be combined: restoring the sphincter itself, restoring pelvic floor support, and restoring sphincter innervations. The concept of stem cell therapy and tissue engineering is another promising approach in order to replace, repair, or enhance the biological functions of a damaged sphincter by injection of new cells. Tissue engineering using muscle progenitor cells or embryonic stem cells holds great promises for reconstructive surgery and is presently a hot area of active research. Recent insights in stem cell biology and biomaterials enable us to achieve in vitro organized three-dimensional cell cultures close to natural tissues. In that context, natural biopolymers such as collagen and fibrin are among the best candidates for such cellular constructs. Stem cells have recently been employed to engineer new functional urogynecologic structures in animal models. The second strategic approach for regenerative therapies of sphincter dysfunction will target restoring pelvic floor support. Synthetic or biological prostheses are developed as "meshes" of various shapes and surgically implanted to restore anatomically the integrity of the pelvic floor. Enriching this prosthesis with progenitor cells will allow inserting potentially "active" meshes, which will give enhanced tolerability and elasticity to the tissues. This extension of the technique of extracellular matrices as three-dimensional prosthesis will help to restore not only the anatomy but also, more importantly, the function of the pelvic floor. Finally, in order to restore a properly functional sphincter, peripheral nerve regeneration by cellular therapy has been developed. Transplanting neurogenic stem cells not only will allow regeneration of damaged axons but will also promote regeneration of a functional sphincter.

A "bubble test," where air is insufflated into the rectum via proctoscope while sterile water or saline is in the operative field, is also a useful technique for intraoperative detection of rectal injuries. It receives fibers from the intermesenteric plexus and the lumbar ganglia of the sympathetic trunks.

Tempeck, 41 years: Appropriate counseling regarding risks and benefits of hormonal treatment is prerequisite to initiating therapy. Typical intercostal nerves (3rd through 6th) run initially along the posterior aspects of the intercostal spaces between the parietal pleura (serous lining of the thoracic cavity) and the internal intercostal membrane. Venous stasis can be caused by � Incompetent, loose fascia that fails to resist muscle expansion, diminishing the effectiveness of the musculovenous pump � External pressure on the veins from bedding during prolonged institutional stays or from a tight cast, bandages, or bands of stockings � Muscular inactivity.
