A computed tomography angiography (CTA) revealed complete occlusion of the left common iliac artery. Surgical embolectomy was carried out and abnormal distal left femoral artery was noted intraoperatively. Postoperative CTA showed a persistent sciatic artery (PSA) on the left and adequate perfusion of the left lower limb. During 2 years follow-up, the patient remained symptom-free with good perfusion to the distal left popliteal artery, anterior and posterior tibial arteries. |
