Shaft Aneurysm of Femoropopliteal Expanded Polytetrafluoroethylene Graft Treated With a Covered Stent

Abstract

Aneurysm formation is a known complication of native vein or synthetic grafts following peripheral bypass surgery. However, with improvement in the material used for prosthetic grafts, these complications are now uncommon. Open surgery has always been the treatment of choice for aneurysms, but the emergence of percutaneous endovascular intervention has led to a safer and easier way to treat aneurysms. In this article, a unique case of aneurysm in a reinforced expanded polytetrafluoroethylene graft placed 11 years ago during a femoropopliteal bypass surgery in a 77-year-old woman with peripheral arterial disease is presented. The aneurysm was treated percutaneously with a self-expanding covered stent resulting in complete isolation of the aneurysm with no complications encountered.
