Spinal Dural Arteriovenous Fistula from Lateral Sacral Artery

ABSTRACT

The authors report a rare case of spinal dural arteriovenous fistula (DAVF) that supplied by lateral sacral artery. A 71-year-old female initially presented with paraparesis and boring pain on lower extremities. Though magnetic resonance imaging suggested a possible spinal DAVF, routine angiographic evaluation was negative. Thereafter, the patient deteriorated progressively and became paraplegic. Definite diagnosis was made through selective pelvic angiogram. The patient was subsequently treated with embolization using mixture of glue and lipiodol. On three months after the embolization, the patient remained paraplegic, but her leg pain was improved remarkably.
