Cystic adventitial disease of the popliteal artery: Two case reports and a review of the literature

Adventitial cystic disease of the popliteal artery

Adventitial cystic disease (ACD) is a vascular disorder most commonly affecting the popliteal artery. ACD is an uncommon and often misdiagnosed cause of lower extremity intermittent claudication that is usually acute in onset and of longer duration than claudication associated with atherosclerosis. We present two cases of ACD affecting the popliteal artery.

Clinical Experience and Management of Squat-Induced Lower Extremity Arterial Ischemia

Popliteal artery entrapment syndrome (PAES) is a rare cause of intermittent claudication in young patients. Unlike the atherosclerotic and degenerative etiologies typically associated with arterial disease, PAES is primarily of anatomic origin. PAES is rarely associated with aneurysmal disease. We present a case and subsequent surgical management of a 47-year-old male who experienced acute limb ischemia secondary to thrombosis of a popliteal artery aneurysm (PAA), who was found to have bilateral PAES and PAAs.

Ultrasound-guided percutaneous aspiration of adventitial cysts in the occluded popliteal artery - clinical results and MR findings at 5-year follow-up

Cystic adventitial disease is a rare disorder that occurs in peripheral arteries. Calf claudication caused by compression of the popliteal artery is a typical presentation of this disease. This is a report of two cases of occluded popliteal artery decompression by percutaneous ultrasound-guided cyst aspiration. In both cases, decompression of the artery was achieved with a significant decrease in the size of adventitial cysts and restoration of flow. Both patients reported complete resolution of symptoms and no calf pain 5 years after the procedure. MR findings and resolution of symptoms in these two patients show the efficacy of percutaneous adventitial cyst aspiration in a 5-year follow-up.
