Purpose: Maintenance of hemodialysis access grafts represents an enormous social and
clinical problem. Current grafts and graft salvage techniques are inadequate. Consequently …

Poor patency of arteriovenous ePTFE grafts remains a major clinical problem. Prophylactic
balloon angioplasty of stenoses has been claimed to prolong graft patency and has been …

PURPOSE: To determine if prophylactic percutaneous transluminal balloon angioplasty
(PTA) can extend patency in functioning virgin ePTFE arteriovenous hemodialysis grafts …

Transluminal angioplasty of venous stenoses in polytetrafluoroethylene vascular access
grafts. Since 1984, percutaneous transluminal angioplasty (PTA) utilizing high pressure …

Background The leading cause of failure of a prosthetic arteriovenous hemodialysis-access
graft is venous anastomotic stenosis. Balloon angioplasty, the first-line therapy, has a …

Purpose: The purpose of this study was to review the 91 failing polytetrafluoroethylene
(PTFE) grafts that were treated at our institution over the past 12 years to better understand …

Abstract Between Jan. 1, 1980, and Dec. 31, 1989, 2187 infrainguinal revascularization
procedures were performed. In 130 of these cases with patent bypasses, hemodynamic …

PURPOSE: To determine the patency of Wallstents placed across the venous anastomosis
of prosthetic bridge grafts after percutaneous graft recanalization. MATERIALS AND …

Purpose To assess the safety and efficacy of an expanded polytetrafluoroethylene stent graft
versus balloon angioplasty for the treatment of in-stent restenosis in the venous outflow of …

Dialysis fistulas and bridge grafts frequently develop outflow stenoses in the venous limb,
leading to graft failure. The venous stenoses are fibrotic and require percutaneous …
