title: Hybrid approach in a case of persistent sciatic artery aneurysm.
abstract: Persistent sciatic artery is a rare congenital vascular malformation with a reported incidence between 0.03% and 0.06%. An 82-yr-old woman presented to our institution with right acute lower limb ischemia compatible with a cardioembolic etiology. A popliteal embolectomy was performed to the patient, and at the end of the procedure, she had bilateral lower limb distal pulses. Six months after the procedure, the patient complained with right lower limb rest pain, an angiography and a computed tomography angiography were performed showing a sciatic artery aneurysm with 4.6 cm of diameter and patency of the sciatic artery to the popliteal artery. A femoropopliteal bypass and retrograde coil embolization of the sciatic aneurysm through the popliteal artery and distal sciatic artery ligation were performed. The patient was discharged 7 days after the procedure, and she remains asymptomatic. Our patient had a complete type of persistent sciatic artery with aneurysmatic degeneration. Correction of the distal ischemia with aneurysm exclusion was achieved with a simple noncomplicated hybrid procedure.
