[An asymptomatic aneurysm of the popliteal artery treated with endoprosthesis].

Stent-graft is considered as a possible alternative to traditional surgery in the correction of popliteal aneurysms but only a few cases have been reported and these are difficult to compare. This new case highlights the feasibility and problems of an endovascular approach. The size of the stent was determined on the basis of preliminary arterial scanning and a measurement guide wire. Strong recommendations to the patient to avoid posture-related kinking of the artery and/or the stent (during occupation-related or other activities) could prevent delayed thrombosis of the stent. The lifetime of the stent can be prolonged by a simple radiosurgical clearance procedure.
