[True aneurysms late complications of revascularization operations in the femoropopliteal tract].

The Authors report three cases of true aneurysms following arterial reconstructive surgery in the femoropopliteal tract. One time it was an autologous venous graft and two times of an endarterectomized artery. At surgery the suture line was intact; so the differential diagnosis with false aneurysms was made. This complication is very rare (less than 1%). That natural history and the treatment are reviewed.
