2 CASES OF CYSTIC ADVENTITIAL DISEASE OF THE POPLITEAL ARTERY - NEW DIAGNOSIS CONSIDERATIONS

The authors report two cases of cystic adventitial disease of the popl iteal artery. Both patients complained of calf claudication and presen ted a thrombosis of the popliteal artery. In one case, magnetic resona nce imaging exhibited a specific preoperative diagnosis. In both cases , at least one communication between the cysts and the capsule of the knee joint was demonstrated, supporting the congenital hypothesis of t he disease. The two cases have been treated by vein graft replacement of the occluded popliteal arteries. Both patients have remained asympt omatic and the two grafts have remained patent during the ninth and tw elfth month follow-up periods.
