title: Case report of adventitial cystic disease of the popliteal artery presented with the ''dog-leg'' sign.
abstract: Adventitial cystic disease of the popliteal artery constitutes an infrequent cause of claudication in non-atherosclerotic young or middle-aged population. Here, we report the case of a 43-year-old female with adventitial cystic disease of the popliteal artery causing left lower leg claudication, detected by duplex scanning. The angio-CT showed the "dog-leg" sign, typical of the aneurysm of the popliteal artery. Surgery was performed through the posterior approach. The cyst and the affected segment of the artery were successfully excised and replaced with an autogenous saphenous vein graft. In 1 year follow-up the graft is patent and the patient is completely asymptomatic.
