1/327. Cerebral radionecrosis following the treatment of parotid tumours: a case report and review of the literature.

    radiotherapy is an accepted part of the treatment of malignant tumours of the parotid gland. The use of radiotherapy in benign parotid tumours, where spillage of tumour cells has occurred at operation, is more controversial. radiotherapy to the parotid bed is not without morbidity. Complications may arise as a result of radiation damage to neighbouring structures and there is also potential to induce malignant disease. A patient, whose postoperative radiotherapy following resection of a pleomorphic salivary gland adenoma was complicated by cerebral necrosis, is discussed. The literature pertaining to morbidity of radiotherapy for parotid tumours is reviewed.

2/327. Fatal polyarteritis nodosa with massive mesenteric necrosis in a child.

    polyarteritis nodosa (PAN) is a rare vasculitic syndrome in childhood. There are few reported cases of ischaemic necrosis of the intestine and even fewer survivors in adults. We report the case of a 10-year-old boy with PAN and an acute abdomen that required operative intervention. Evidence was found of mesenteric arteritis with large ischaemic segments resulting in infarction and perforation.

3/327. Confirmation of arterial deficiencies in a limb with necrosis following clubfoot surgery.

    This study describes postoperative necrosis of the hallux and first ray in a child with clubfoot. Arteriography performed on this child's lower limbs demonstrated, in the operated leg, hypoplasia of both the anterior and posterior tibial arteries and failure of the dorsalis pedis artery to traverse the tarsus and complete the deep plantar arch. Previously, congenital vascular deficiency was suggested to predispose such operated limbs to necrosis. These findings confirm the association between vascular deficiency and necrosis. In this present study, the metabolic demands of wound healing were sufficient in a limb with vascular deficiency to cause localized distal hypoperfusion leading to cyanosis and necrosis of the hallux and medial foot.

4/327. cricoid cartilage necrosis after arytenoidectomy in a previously irradiated larynx.

    Several open and endoscopic surgical techniques are available to provide an adequate airway for patients with bilateral vocal cord paralysis. Transoral laser arytenoidectomy has repeatedly been reported to be a reliable and effective minimally invasive procedure for airway restoration. To our knowledge, there have been no previous reports of serious complications, other than poor vocal results, aspiration, and failed decannulation in individual patients, that have resulted from this intervention. We report a case in which arytenoidectomy led to severe complications and death. Prior irradiation is suspected to be a causative factor. To prevent such an outcome, we believe that operative settings should be chosen that avoid deep thermal injury of the laryngeal framework.

5/327. Progressive perinatal bowel obstruction--a rare cause of short-bowel syndrome.

    A girl was born after an uneventful pregnancy of 36 weeks. Prenatally, distended bowel loops had been seen on ultrasound. Multiple small-bowel atresia was diagnosed and treated surgically. In the course of the next eleven weeks, previously patent segments of small bowel became obstructed. In 4 separate operative sessions, several segments of jejunum and ileum were resected, leaving 23 cm of ileum with the ileocecal valve in place. On microscopic examination of all resected material, necrosis of the mucosa was found consistent with ischemia. The child survived and tolerated full enteral feeding at the age of 8.5 months. The origin of the progressive obliterating process remains unknown.

6/327. oxacillin-induced tissue necrosis.

    OBJECTIVE: To report a case of oxacillin-induced tissue necrosis in which recommended concentration guidelines for dilution and administration were used. oxacillin concentration data, potential risk factors, and treatment options for extravasation injuries are also briefly reviewed. CASE SUMMARY: oxacillin was infused peripherally by infusion pump in a 79-year-old white woman as prophylactic antibiotic coverage for permanent pacemaker placement. oxacillin extravasation occurred after the second postoperative dose. A dime-sized area of necrosis was noted at the heparin-lock insertion site. DISCUSSION: Only one case of oxacillin-induced necrosis has been reported. The degree of damage and concentration of drug used were not specifically described. Concentration may play a role in the appearance or absence of tissue damage after an antibiotic extravasation and should be taken into consideration when evaluating a drug's tissue toxicity potential. CONCLUSIONS: The potential exists for oxacillin 50 mg/mL to cause tissue damage in humans if an extravasation occurs. This reaction may be avoided with use of a less-concentrated preparation, avoidance of infusion pump administration, and identification of high-risk patients.

7/327. The application of immobilized polymyxin b fiber in the treatment of septic shock associated with severe acute pancreatitis: report of two cases.

    The elimination of endotoxin by direct hemoperfusion over immobilized polymyxin b fiber (PMX-F) was carried out in two patients who developed septic shock associated with severe acute pancreatitis. Parameters such as blood pressure, body temperature, and plasma endotoxin level improved after PMX-F treatment, and the infected lesions were successfully and safely removed by surgery. Although an aggressive operative strategy of debridement with ultimate closure over drains is generally associated with low mortality in patients with this devastating disease, we often hesitate to perform this operation due to the poor condition of the patient in the acute period, with multiple organ failure and/or septic shock status, and also because of the difficulty in diagnosing the pancreatic infection. In this situation, endotoxin elimination using PMX-F is a useful tool for treating secondary pancreatic infections to help the patient recover in preparation for surgery, or for treating perioperative endotoxemia.

8/327. Treatment and stabilization of complex wounds involving the pelvic bone, groin, and femur with the inferiorly based rectus abdominis musculocutaneous flap and the use of power color Doppler imaging in preoperative evaluation.

    The authors present case reports demonstrating the trilevel utility of the inferiorly based rectus abdominis musculocutaneous flap in the closure of complex wounds involving the pelvis, groin, and femur that had failed previously or were not amenable to traditional closure techniques. The use of the rectus abdominis flap was especially advantageous for achieving infection eradication and large dead space closure. Additionally they present the emerging technique of power color Doppler imaging as a valuable tool in preoperative flap planning. This technique is particularly useful in evaluating the candidacy for rectus abdominis musculocutaneous flap placement of patients with a prior history of abdominal surgeries, trauma, infection, irradiation, or other conditions that might compromise the patency of the deep inferior epigastric vessels.

9/327. Arterial occlusion and thrombus aspiration after total knee arthroplasty.

    Arterial occlusion after total knee arthroplasty is an uncommon complication. In the literature only a few cases have been reported, and non consensus exists on the optimal management for this condition. The authors report two patients with popliteal artery thrombosis in the early postoperative period. Both patients were treated with percutaneous thrombus aspiration, a technique that has not been reported previously for this indication. In both patients complete restoration of arterial perfusion and limb salvage was achieved, although ischemic necrosis of the anterior compartment muscles of the lower leg could not be prevented.

10/327. Descending necrotizing mediastinitis with sternocostoclavicular osteomyelitis and partial thoracic empyema: report of a case.

    We present herein the case of a 50-year-old woman in whom descending necrotizing mediastinitis originating from an anterior neck abscess spread to the left upper bony thorax, resulting in osteomyelitis of the left sternocostoclavicular articulation and left partial thoracic empyema. Transcervical mediastinal irrigation and drainage was performed with aggressive antibiotic therapy, followed by resection of the left sternocostoclavicular joint and debridement of the anterior mediastinum. The patient had an uneventful postoperative course, and her left arm and shoulder mobility was well preserved.
