Complete Rupture of Polytetrafluoroethylene-covered Endoprosthesis after Exclusion of a Popliteal Aneurysm.

Popliteal artery aneurysm (PAA) is the most commonly reported peripheral artery aneurysm. The usual treatment is exclusion bypass with a saphenous vein. However, the availability of medium size covered stent graft is an attractive option. By performing this procedure percutaneously, we can shorten the hospital stay of the patient. Favourable early and long-term results have been reported; however, little is known about the durability of the procedure. Given the mobile location of the stent-graft close to the knee joint, graft damage can be expected. We describe a case of complete rupture of a Viabahn(®) endoprosthesis which was inserted to exclude a PAA.
