1/250. Aortobronchial fistula after coarctation repair and blunt chest trauma.

    A 34-year-old man had development of an aortobronchial fistula 17 years after patch aortoplasty for correction of aortic coarctation and 5 years after blunt chest trauma, an unusual combination of predisposing factors. The clinical presentation, characterized by dysphonia and recurrent hemoptysis, and the surgical findings suggested the posttraumatic origin of the fistula, which was successfully managed by aortic resection and graft interposition under simple aortic cross-clamping, associated with partial pulmonary lobectomy. When hemoptysis occurs in a patient with a history of an aortic thoracic procedure, the presence of an aortobronchial fistula should be suspected. early diagnosis offers the only possibility of recovery through a lifesaving surgical procedure.

2/250. Fungal endocarditis in critically ill children.

    All cases of infective endocarditis occurring from January 1990 to December 1996 at our institution were reviewed, with a special focus on fungal endocarditis. Five critically ill children with fungal endocarditis and eleven children with bacterial endocarditis were recorded. The proportion of fungal endocarditis in our series was 5/16 (31%) and candida albicans (4/5) was the most common fungal pathogen. Only one patient required heart surgery because of a loose patch but all the others were treated only by medical management for cure. The hospital survival rate was 80% (4/5) and the overall long-term survival rate was 60% (3/5) with only one death directly related to fungal infection. CONCLUSION: Despite the small number of cases, a sole medical approach including amphotericin b and long-term fluconazole prophylaxis for the treatment of fungal endocarditis in critically ill children seems to offer an alternative to surgical treatment which may be kept for failure of medical treatment.

3/250. Three ventriculoplasty techniques applied to three left-ventricular pseudoaneurysms in the same patient.

    A 59-year-old male patient underwent surgery for triple-vessel coronary artery disease and left-ventricular aneurysm in 1994. Four months after coronary artery bypass grafting and classical left-ventricular aneurysmectomy (with Teflon felt strips), a left-ventricular pseudoaneurysm developed due to infection, and this was treated surgically with an autologous glutaraldehyde-treated pericardium patch over which an omental pedicle graft was placed. Two months later, under emergent conditions, re-repair was performed with a diaphragmatic pericardial pedicle graft due to pseudoaneurysm reformation and rupture. A 3rd repair was required in a 3rd episode 8 months later. Sternocostal resection enabled implantation of the left pectoralis major muscle into the ventricular defect. Six months after the last surgical intervention, the patient died of cerebral malignancy. Pseudoaneurysm reformation, however, had not been observed. To our knowledge, our case is the 1st reported in the literature in which there have been 3 or more different operative techniques applied to 3 or more distinct episodes of pseudoaneurysm formation secondary to post-aneurysmectomy infection. We propose that pectoral muscle flaps be strongly considered as a material for re-repair of left-ventricular aneurysms.

4/250. Restenosis following carotid endarterectomy--clinical profiles and pathological findings.

    Restenosis following carotid endarterectomy is not a rare condition. Among 122 endarterectomies we experienced, five restenoses (4.1%) were encountered and treated by the second surgery. The present report clarifies the clinical profiles and pathological findings of restenosis following carotid endarterectomy. Mean age of restenosis group (59 years old) was not significantly different from the group without restenosis (62 years old). Average duration between the first endarterectomy and the second surgery was 17 months (8-30 months). Initial symptoms were transient ischemic attack in three sides, minor stroke in one side, and asymptomatic in one. Degree of stenosis was tight (> or = 90%) in two and moderate (70-89%) in three. It is interesting to note that no ulcer was noted in the first endarterectomy specimen. At surgery for restenosis, two cases had symptoms and another two cases were asymptomatic, though all had neck bruits. Four of five lesions were treated by short venous graft from common carotid artery to distal internal carotid artery and another lesion was treated by second endarterectomy and Dacron patch graft. pathology was studied in four and all showed myointimal hyperplasia. Three of four restenosis tissues showed mutant form p53 by immunohistochemistry. The present study indicates that restenosis following carotid endarterectomy is not a rare status. Short venous bypass across the stenotic portion is the treatment of choice. Monoclonal growth of smooth muscle with mutant form p53 might be related to the restenosis.

5/250. Glutaraldehyde-fixed heterologous pericardium for vena cava grafting following hepatectomy.

    BACKGROUND/AIMS: Glutaraldehyde-fixed heterologous pericardium has been widely used for grafts in cardiac surgery. We applied it for inferior vena cava (IVC) patch grafting following combined resection of the liver and the IVC. METHODOLOGY: IVC grafting using a glutaraldehyde-fixed horse pericardium following combined resection of the liver and the IVC was performed in 2 patients--one with hepatocellular carcinoma and the other with hepatic metastasis following rectal cancer. The retrohepatic vena cava defect was closed with a 10 x 5 cm patch in one patient and a 7 x 4 cm patch in the other. RESULTS: Hepatic vascular exclusion was avoided in both patients. The IVC exclusion period was 40 min for the first patient and 25 min for the second. One patient required a veno-venous bypass with an active centrifugal pump of 153 min. There was no complication and no graft infection. The microscopic extension to the IVC was evident in one patient, and fibrous adhesive was evident in the IVC wall of the other. One patient died of hepatic failure 3 years and 6 months after surgery, and the other died of hepatic recurrence 7 months after surgery. Both grafts were patent, without calcification and stricture, until the patients' death. CONCLUSIONS: Glutaraldehyde-fixed heterologous pericardium is an option for IVC grafting.

7/250. Symptomatic venous hypertension because of occult iliofemoral deep vein thrombosis: a report of two cases.

    Two 25-year-old males with symptomatic venous hypertension (venous claudication, n = 1; swollen leg, n = 1) were evaluated for iliofemoral venous occlusive disease. One patient had a common femoral vein/external iliac vein occlusion with no history of deep vein thrombosis or trauma. The second patient had an acute deep vein thrombosis superimposed on a chronic external iliac vein stenosis. No source of extrinsic venous compression was identified in either patient. Venous reconstruction with vein bypass (patient no. 1) and vein patch angioplasty (patient no. 2) led to resolution of their hypertensive symptoms. Intraoperative examination of the involved vein segments revealed chronic changes consistent with a prior occult deep vein thrombosis in both patients. Occult iliofemoral deep vein thrombosis in young healthy males is rarely seen. The acute deep vein thrombosis may manifest minimal or no symptoms but it can lead to chronic venous occlusive disease and serious post-phlebitic morbidity. In this context, these two cases are discussed with a review of the pertinent literature.

8/250. Mesh plug migration into scrotum: a new complication of hernia repair.

    hernia repair is one of the most frequent operative procedures performed throughout the world. The technique has continued to evolve and we now are performing these repairs utilizing mesh as a patch and also as a plug. The mesh plug concept has been advocated by Rutkow and others. With this change in technique, we have seen a new complication of hernia repair - the migration of the mesh plug from the original hernia repair site into the scrotum. It presented as a large tender mass in the scrotum of a 45-year-old male who had had previous recurrent surgery. In addition, he again had a recurrent incarcerated hernia. Correction of the hernia and resection of the migrated mesh plug from the scrotum were carried out. It is recommended that both the patch and the plug be into position to avoid or reduce the risk of such a recurrence and plug migration.

9/250. Prosthetic valve replacement in Ebstein's malformation: 30-year follow-up.

    This report addresses a 42-year-old asymptomatic patient who underwent prosthetic replacement of his tricuspid valve 31 years previously for Ebstein's malformation. A ball valve prosthesis was implanted to replace the abnormal valve. Furthermore, he had concomitant closure of a large atrial septal defect with a perforated patch together with plication of the atrialized ventricular segment. The patient is asymptomatic, and it remains noteworthy that he has not been on coumadin for about 30 years.

10/250. Separate revascularization of the visceral arteries in thoracoabdominal aneurysm repair.

    We successfully repaired a ruptured aortic patch containing the visceral arteries after thoracoabdominal aneurysm repair in a young patient with marfan syndrome. This unexpected and tricky situation was treated by separate revascularization of each visceral artery using small-caliber prosthetic grafts as interposition between the aortic prosthesis and the ostia of the visceral arteries.
