Interposition grafting of popliteal artery cystic adventitial disease: case report

Cystic adventitial disease of the popliteal artery is a rare cause of leg claudication occurring primarily in young adults. We report a case of a 41-year-old athletic man who presented with rapidly progressive left leg claudication. Using duplex ultrasound and magnetic resonance angiography, a diagnosis of popliteal artery cystic adventitial disease was made. The cystic popliteal artery was resected and replaced using a prosthetic interposition graft. At the 1.5-year follow-up, the cysts have recurred; however, the related symptoms have not. This is in contrast to a previously reported case of interposition saphenous vein grafting requiring resection due to invasion by recurrent cysts within 6 months.
