A hybrid approach to persistent sciatic artery fusiform aneurysm repair

A persistent sciatic artery is a rare vascular anomaly that is prone to early atherosclerotic development and aneurysmal degeneration. Repair of the degenerative aneurysm is critical because it can lead to rupture, thrombosis, distal embolization, and sciatic nerve damage from compression. We report a case of a symptomatic unilateral persistent sciatic artery fusiform aneurysm that was treated using a simultaneous open surgical and endovascular approach. The patient underwent right common femoral to below-knee popliteal artery bypass and percutaneous endovascular embolization of the right sciatic artery aneurysm. Proper surgical intervention determined by the patient's comorbidities and unique anatomy achieved favorable outcomes.
