Hemodialysis graft infections typically occur as a result of contamination by skin flora at the time of insertion or become secondarily infected after high-grade bacteremia. Infection of implanted vascular devices with filamentous fungi is rare. We report a case of infection of an implanted polytetrafluoroethylene dialysis graft with Fusarium incarnatum/equiseti that did not grow in cultures of...

The steady decline with time in patency of expanded polytetrafluoroethylene (e-PTFE) dialysis shunts led to a trial protocol of postimplantation surveillance to identify those grafts at risk for thrombosis. Duplex scanning is a noninvasive, reproducible method of monitoring anatomic and hemodynamic aspects of graft function that provides the surgeon with an opportunity for early operative inter...

Received April 2008 Accepted November 2008 INTRODUCTION Short or damaged renal vessels represent a serious challenge during kidney transplantation. The increasing risk of thrombosis, bleeding, or compromised kidney function often leads to declining the donated kidneys with damaged vessels.(1) We here describe 5 kidney transplantations in which a polytetrafluoroethylene (PTFE) vascular graft was...

A 55-year-old male with a history of iliac artery - popliteal artery polytetrafluoroethylene graft bypass presented 2 years later with sudden onset gross hematuria with sepsis. Computed tomography (CT) angiography was suggestive of fistula between ureter and iliac artery which was treated with arterial covered stent graft. The patient presented 2 weeks later with watery discharge from the previ...

PURPOSE Use of a composite graft combining a polytetrafluoroethylene graft with an autogenous vein is an option for limb salvage in the absence of an adequate single segment vein graft. We aimed to investigate the results of infrainguinal bypass with a composite graft. MATERIALS AND METHODS We retrospectively reviewed 11 infrainguinal arterial bypasses on 11 limbs which underwent surgery from...

OBJECTIVES In middle hepatic vein dominant livers, the anterior segment of the right lobe of the liver (segments V and VIII) drains mainly into the middle hepatic vein. In these donors, when right lobe grafts are procured without the middle hepatic vein, the graft may harbor large segment V and/or VIII veins that need reconstruction to avoid graft congestion and subsequent graft dysfunction. Dr...

We describe a case of infrarenal aortic hypoplasia in a 52-yr-old woman who presented with claudication. Computed tomographic angiography revealed an abrupt absence of the infrarenal aorta, with collateral flow reconstituting the iliofemoral systems. After a polytetrafluoroethylene graft was interposed between the aortic stump and the iliac bifurcation, the patient's claudication resolved.

AIM The aim of the current report is to illustrate an alternative technique for the treatment of oroantral fistula (OAF), using an autologous bone graft integrated by xenologous particulate bone graft. BACKGROUND Acute and chronic oroantral communications (OAC, OAF) can occur as a result of inadequate treatment. In fact surgical procedures into the maxillary posterior area can lead to inadver...
