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.
