title: [Cystic degeneration of the adventitia of the popliteal artery after PTA of the superficial femoral artery].
abstract: Cystic adventitial degeneration is rare. Most frequently it occurs in the popliteal artery, occasionally it may be found in other arteries and even in veins. It is always localized in joint-adjacent vessel areas and appears to originate in ectopic synovial tissue occasionally with a stemlike connection with the adjacent joint. The diagnosis of a cystic adventitial degeneration should be considered in cases of isolated stenosis or occlusion of the popliteal artery. Realtime ultrasound or computerized tomography may help to establish the diagnosis. The treatment of choice is surgival removal of the cysts or reconstruction with an autologous vein interponate. A rare case of simultaneous occurrence of cystic adventitial degeneration and arteriosclerotic occlusive disease is described.
