1/54. hypoglossal nerve injury as a complication of anterior surgery to the upper cervical spine.Injury to the hypoglossal nerve is a recognised complication after soft tissue surgery in the upper part of the anterior aspect of the neck, e.g. branchial cyst or carotid body tumour excision. However, this complication has been rarely reported following surgery of the upper cervical spine. We report the case of a 35-year-old woman with tuberculosis of C2-3. She underwent corpectomy and fusion from C2 to C5 using iliac crest bone graft, through a left anterior oblique incision. She developed hypoglossal nerve palsy in the immediate postoperative period, with dysphagia and dysarthria. It was thought to be due to traction neurapraxia with possible spontaneous recovery. At 18 months' follow-up, she had a solid fusion and tuberculosis was controlled. The hypoglossal palsy persisted, although with minimal functional disability. The only other reported case of hypoglossal lesion after anterior cervical spine surgery in the literature also failed to recover. It is concluded that hypoglossal nerve palsy following anterior cervical spine surgery is unlikely to recover spontaneously and it should be carefully identified.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
2/54. Unexpected findings in the investigation of an airplane crash.We report on the discovery at autopsy of an unexpected cause of a crash during landing of a small sports plane with four people on board. Surprisingly, an intact bullet and fragments of the casing were found in the body of the pilot. As expected, autopsy of the other passengers predominantly revealed signs of polytraumatization. In addition, one passenger had a tunnel wound to the left hand and another, a soft tissue tear between the thumb and forefinger of the right hand. These wounds were considered to be associated with a shooting incident in the cabin. The autopsy findings and additional gunpowder trace investigations suggested that the pilot had been incapacitated by a shot from behind, resulting in the plane crash. The present findings underscore the importance of conducting autopsies on all air crash victims.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
3/54. Benign lymphangioendothelioma of the thigh simulating a low-grade angiosarcoma.Benign lymphangioendothelioma (BL) is a rare vascular neoplasm that can histopathologically mimic a low-grade angiosarcoma or the patch stage of Kaposi sarcoma. We report on the case of a 49-year-old man with a benign lymphangioendothelioma on the right thigh that evolved on a vascular birthmark after a trauma. Because of constant pain and the slow but progressive growth of the lesion, we decided to excise the tumor. Three stages of surgery were needed to obtain negative margins. We review the reports of BL to date, with special attention to those that developed after trauma and those that had a preexistent vascular lesion, and expound on the histopathologic differential diagnosis with low-grade angiosarcoma.- - - - - - - - - - ranking = 0.32327590430085keywords = neoplasm (Clic here for more details about this article) |
4/54. Treatment of hostile midline back wounds: an extreme approach.The basic principles of successful wound closure remain the same: careful preoperative evaluation, removal of underlying nonviable tissue, and well-vascularized soft-tissue coverage. Many complex or "hostile" back wound closures also require stabilization of the spine and a two-layered wound closure. The use of long arteriovenous fistulas with free tissue transfer provides an additional weapon for the treatment of these complex wounds.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
5/54. Traumatic venous aneurysm of the popliteal vein with outcome: a case report and review of the literature.A case of sudden death due to recurrent pulmonary thromboembolism is described. The fatality took place three and a half weeks following blunt trauma to the left popliteal region. The patient died unexpectedly. autopsy revealed the source of the emboli as a sacciform venous aneurysm of the popliteal vein, an entity seldom described, but important to consider in cases of soft tissue popliteal masses or unexplained pulmonary embolism, especially in otherwise healthy individuals.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
6/54. Post-traumatic fibro-osseous lesion of the ribs and scapula (sclerosing xanthofibroma).Fibrous lesions of bone may be difficult to classify. Their etiology is controversial, most being considered to be developmental lesions rather than true neoplasms. We describe a patient with post-traumatic fibro-osseous lesion of the ribs, also known as sclerosing xanthofibroma; a lesion believed to be a reactive response to intramedullary hemorrhage following chest wall trauma. Clinically, the lesions in our patient were thought to be metastatic disease because of their multifocal appearance. An extensive clinical and laboratory metastatic evaluation with surgical resection of one of the lesions using intraoperative gamma probe was undertaken. In addition to the multiple rib involvement, our case also showed a lesion in the scapula. The pathologic and radiologic features of this entity are reviewed along with the summary of the differential diagnosis.- - - - - - - - - - ranking = 0.32327590430085keywords = neoplasm (Clic here for more details about this article) |
7/54. Versatility of the free anterolateral thigh flap for reconstruction of soft-tissue defects: review of 140 cases.From August 1995 to June 1999, 140 free anterolateral thigh (ALT) flaps were transferred to reconstruct a variety of soft-tissue defects. The size of ALT flap ranged from 10 to 33 cm in length and 4 to 14 cm in width. Based on the anatomic variations of the perforators, the blood supply to the skin island came from the septocutaneous perforators only in 19 patients (13.6%), arising from the descending or transverse branch of the lateral circumflex femoral artery (LCFA), or originating directly from LCFA. The other flaps were supplied by musculocutaneous perforators that were elevated as a true perforator flap via intramuscular dissection (N = 34, 24.3%), or used a cuff of vastus lateralis muscle for added bulk (N = 87, 62.1%). The overall success rate was 92% (129 of 140). After a 2-year follow-up, all flaps have healed unevenffully and donor thigh morbidity is minimal. Anatomic variations must be considered if the ALT flap is to be used safely and reliably.- - - - - - - - - - ranking = 5keywords = soft (Clic here for more details about this article) |
8/54. High-pressure water jet injuries: a surgical emergency.Injuries from high-pressure jet devices are surgical emergencies characterised by small entry wounds with extensive internal damage. Three factors are involved in these injuries. Physical injury can include local soft tissue disruption and vascular and nerve damage; chemical properties of the injectate can exacerbate compressive vascular injuries with increased oedema and inflammation; water-jet injuries can be contaminated by virulent organisms and foreign matter which can lead to unusual infections. Management is usually similar to that for injuries caused by high-velocity missiles, and involves aggressive debridement, irrigation and decompression followed by careful monitoring, and appropriate antibiotic therapy.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
9/54. hemangiopericytoma. An analysis of 106 cases.A series of 106 cases of hemangiopericytoma was analyzed. The neoplasms occurred principally in adults (median age, 45 years), were deep seated, and were most common in the thigh (27 cases) and the pelvic retroperitoneum (26 cases). A painless mass was the first symptom in 96 of the patients. The median size of the excised tumors was 6.5 cm. Surgical removal of the tumor was often complicated by hemorrhage because of marked dilatation of the vascular bed in the vicinity of the neoplasm, probably as the result of rapid exchange of blood from the arterial to the venous circulation within the tumor. Microscopically, benign and malignant forms could be distinguished. The latter were characterized by increased cellularity, prominent mitotic activity, and foci of necrosis or hemorrhage. Follow-up information was obtained in 93 cases. Seventy-one of the 93 patients were living (two with recurrence and four with metastasis), and 22 had died (13 as the result of recurrence or metastasis in more than two-thirds of the related causes). recurrence preceded metastasis in more than two-thirds of the patients with evidence of metastasis. The 10 year survival rate was 70 per cent. The morphologic differences from other mesenchymal tumors showing a hemangiopericytoma-like vascular pattern are discussed, and the close resemblance of hemangiopericytoma to richly vascular forms of fibrous histiocytomas and synovial sarcoma is emphasized. Congenital or infantile hemangiopericytoma is described as a separate entity having a distinctive microscopic pattern and behavior.- - - - - - - - - - ranking = 0.64655180860171keywords = neoplasm (Clic here for more details about this article) |
10/54. Calcific myonecrosis: keys to early recognition.Calcific myonecrosis is a rare, late sequela of trauma occurring almost exclusively in the lower extremity which may be confused with an aggressive primary neoplasm. The platelike mineralization pattern seen on radiographs is characteristic but not widely recognized by clinicians. Three cases of calcific myonecrosis are reported, unique in that two presented for care following infection and that one had extended to involve the muscle compartments of the foot, a previously unreported site.- - - - - - - - - - ranking = 0.32327590430085keywords = neoplasm (Clic here for more details about this article) |
