title: Closure of a surgically created arteriovenous fistula with a covered stent-graft in a patient with venous ambulatory hypertension--a case report.
abstract: The purpose of this paper is to report the use of a covered stent-graft in the endovascular treatment of a surgically created arteriovenous fistula. A 37-year-old woman with symptomatic venous ambulatory hypertension underwent a left common femoral vein-to-right common iliac vein bypass using 10 mm ringed polytetrafluoroethylene (PTFE) with creation of an arteriovenous (AV) fistula from the superficial femoral artery to the PTFE graft. At 1 year postoperatively, recurrent symptoms thought to be due to the arteriovenous fistula were treated by placement of an 8 mm x 10 cm Viabahn covered stent-graft. Placement was via crossover technique from the right common femoral artery using a 9 French sheath. At 2 months' follow-up symptoms had resolved, the AV fistula was occluded, and venous bypass remained patent. Focal arteriovenous fistulas of the proximal superficial femoral artery can be treated safely with a covered stent-graft via an endovascular approach.
