摘要
persistent sciatic artery is a rare congenital anomaly of the circulatory system. since there are few cases described in the literature, there is no consensus on diagnostic and treatment methods. the authors report on a 59-year-old male patient with history of progressive intermittent claudication in the right calf, associated with pulsatile mass in the popliteal fossa and absence of distal pulses. tomography angiography of the abdominal aorta and lower limbs showed persistent right sciatic artery. selective digital subtraction angiography of the sciatic artery was also performed for surgical planning. the patient was submitted to femorofibular bypass with reverse ipsilateral great saphenous vein and ligation of the sciatic artery in the pelvis using retroperitoneal approach.
