Popliteal Artery Adventitial Cysts Replacement with a Great Saphenous Vein Graft

Abstract

Adventitial cyst is a relatively rare disease in which a colloid-like substance accumulates in the adventitia or external elastic lamina of the arteries, causing stenosis or obstruction. The patient is a 61-year-old male who referred to our department with intermittent claudication of the right lower extremity. We diagnosed him with a right popliteal artery adventitial cyst using ultrasonography and performed contrast-enhanced CT to evaluate the lesion and the saphenous veins. The patient was placed in the supine position for harvesting the great saphenous vein (GSV). Afterward, we repositioned him in the prone position, resected the lesion, and replaced it with the GSV graft. 15 months have passed since the surgery, and the patient shows no signs of recurrence.
