Targeted Embolization of Vertebral Arteriovenous Fistula Associated with Type 1 Neurofibromatosis: Case Report

Abstract

Objective: Vertebral arteriovenous fistula (AVF) is rare in type 1 neurofibromatosis (NF1). We report a case of NF1 complicated by vertebral AVF, for which transarterial targeted embolization of the fistula resulted in a favorable outcome.

Case Presentation: A 44-year-old man with NF1 presented with cervical radiculopathy of the right fifth nerve root due to vertebral AVF. The fistula was completely occluded by transarterial targeted coil embolization of venous pouch of the fistula, and his neurological deficits got better. After a year follow-up, the fistula was completely occluded, and the patient's radiculopathy recovered almost completely.

Conclusion: Targeted embolization via artery can be the first-line treatment method for vertebral AVF associated with NF1.
