Arteriovenous malformation arising on persistent sciatic vessels.

BACKGROUND: A persistent sciatic artery is a rare congenital anomaly, and an arteriovenous malformation arising on persistent sciatic vessels is extremely rare. METHODS: This report presents the case of a 30-year-old female with persistent sciatic vessels complicated with an arteriovenous malformation in the right buttock. It was surgically inaccessible, and a three-staged transcatheter embolization using 20% N-butyl-cyanoacrylate/80% lipiodol was performed. RESULTS: The arteriovenous malformation was shown to have been extinguished by multidetector computed tomography. CONCLUSIONS: This report presents the first case of persistent sciatic vessels complicated with an arteriovenous malformation treated by transcatheter embolization.
