Abstract
Persistent sciatic artery (PSA) is a rare congenital anomaly. We present a case of a 75-year-old woman who complained of right buttock pain with right PSA aneurysm and hypoplastic external iliac and femoral arteries. The PSA was ligated at the pelvis and the adductor magnus canal, and bypass between the internal iliac artery and the popliteal artery was performed. Postoperatively, the PSA including the aneurysm was completely thrombosed and the symptoms disappeared.
