Abstract
A 58-year-old man presented with a traumatic vertebro-vertebral arteriovenous fistula (VVAVF) after attempting suicide by thrusting scissors into his right anterior cervical region. Two months later he noticed weakness and numbness of the right upper extremity. Examination revealed bruit in the right neck, no cranial nerve palsy, and weakness of the right deltoid and biceps muscles. Hypalgesia and hypesthesia were noted in the right C5 and C6 dermatomes. Magnetic resonance imaging demonstrated a mass lesion on the right ventral aspect of the spinal canal from C2 to C7. Right vertebral artery angiography showed a pseudoaneurysm of the right vertebral artery and a high-flow arteriovenous fistula between the right vertebral artery and vein. The right vertebral artery was occluded with detachable coils because the fistula showed high blood flow and the right posterior inferior cerebellar artery was well opacified from the left vertebral artery. This procedure resulted in complete obliteration of the arteriovenous fistula. The preoperative motor and sensory symptoms improved. Endovascular treatment by coil embolization was effective in our patient with traumatic VVAVF.
