arteriovenous fistula is considered as a prerequisite in patients with chronic renal failure undergoing hemodialysis. the purpose of this study was to compare the effectiveness and side effects if any of native vein and synthetic grafts in these patients. from april 2002 till july 2003, a total of 37 patients were referred to us for the utilization of these grafts. in 16 out of these patients w...

Perigraft seroma is a rare complication of polytetrafluoroethylene grafts especially in the lower limb. It is often difficult to treat and recurrence is common. We present a case of a young woman who sustained a persistent perigraft seroma following a polytetrafluoroethylene graft in the proximal thigh, which was implanted as an alternative to an arteriovenous fistula. The cause was not ascerta...

There is still debate whether sintethic graft (polytetrafluoroethylene or Dacron) is equivalent to vein as bypass graft material for the above-knee femoropopliteal bypass. Therefore, we performed prospective randomized trial to compare vein with polytetrafluoroethylene/dacron for femoropopliteal bypasses with the distal anastomosis above the knee. Between January 2000 and June 2003, 121 femorop...

BACKGROUND In femoropopliteal bypass surgery, the use of saphenous vein grafts is preferable, but synthetic grafts are widely used above the knee. The objective of this meta-analysis was to assess the long-term patency of femoropopliteal bypass grafts classified as above-knee polytetrafluoroethylene, above-knee saphenous vein, or below-knee saphenous vein. METHODS Studies published from 1986 ...

Leiomyosarcoma of the vena cava is a rare malignant tumor. A 61-year-old woman was admitted with right upper quadrant abdominal pain. Computed tomography revealed a retrohepatic vena cava tumor originating 2 cm below the confluence of the hepaic veins and ending 2 cm above the renal veins. The tumor was resected with 1 cm clear surgical margins, without requiring liver resection. Polytetrafluor...

Results One patient with subclavian artery aneurysm underwent resection of the aneurysm and subclavian-axillary bypass surgery with brachial embolectomy using a polytetrafluoroethylene (PTFE) graft; whereas the other patient underwent resection of the aneurysm and subclavian-axillary bypass surgery with saphenous vein graft. In addition to resection of the aneurysm, three out of 6 patients with...

We report a 71-year old man with coronary artery disease. Complete coronary revascularization was not possible with autologous grafts; therefore, a 4-mm expanded polytetrafluoroethylene graft was implanted that had been seeded preoperatively with autologous vascular endothelial cells. At 9-year follow-up, the patient is asymptomatic and shows a patent graft.

INTRODUCTION Enterobacter cloacae infections are common among burn victims, immunocompromised patients, and patients with malignancy. Most commonly these infections are manifested as nosocomial urinary tract or pulmonary infections. Nosocomial outbreaks have also been associated with colonization of certain surgical equipment and operative cleaning solutions. Infections of an aortobifemoral pro...

Among the possible complications of hemodialysis polytetrafluoroethylene (PTFE) graft creation, perigraft seromas are rare, but sometimes troublesome. Debridement with drainage is usually the method of treatment. However, recurrence is not unusual. Herein we describe 2 cases of recurrent perigraft seroma treated by a simple but effective surgical method: excision of the pseudocapsule and revisi...
