Case ReportAdventitial cystic disease of the popliteal artery treated by bypass graft utilizing the short saphenous vein: A case report

•CT or MRI scan is crucial in the diagnosis of adventitial cystic disease (ACD).•Surgery is the first line in the treatment of ACD at the popliteal artery.•The short saphenous vein was successfully employed in bypass graft surgery.

IntroductionAdventitial cystic disease is relatively rare vascular disease, frequently occurred in the popliteal artery. No definitive treatment has been established yet.Prentation of caseA 53-year-old woman presenting intermittent claudication of the right leg was diagnosed as adventitial cystic disease of popliteal artery. Percutaneous balloon dilation yielded an immediate recurrence. The disease was successfully treated by bypass grafting utilizing the short saphenous vein to replace the part of the popliteal artery containing the adventitial cyst. No postoperative complication was found six months after surgery.DiscussionComparing to a great saphenous vein, a short saphenous vein as a material of bypass graft has a significant advantage, as only a single surgical field is necessary.ConclusionWe propose that bypass graft surgery employing a short saphenous vein is worth considering as a treatment of adventitial cystic disease at the popliteal artery.
