Angioplasty for Persistent Sciatic Artery Occlusion

Abstract

Persistent sciatic artery (PSA) is a rare congenital malformation and often result in aneurysmal or occlusive changes. This case report described a patient who underwent angioplasty for persistent sciatic artery occlusion. A 66-year-old man was referred with right leg claudication. The ankle brachial index (ABI) was reduced to 0.63 on the right side. Computed tomography showed a right PSA was occluded. The right superficial femoral artery was hypoplastic. Blood supply to the right popliteal artery by the collateral arteries was detected from right superficial femoral artery. Angioplasty of collateral artery was performed. Postoperatively, ABI improved to 0.88 on the right side. After follow-up, ABI reached 1.01 and claudication was disappeared.
