Coil embolization of vertebro-vertebral arteriovenous fistula: a case report

Vertebro-vertebral arteriovenous fistulas (VVFs) are not uncommon, but they usually present with benign symptoms such as neck murmur. We report a case of VVF presenting with myelopathy which was successfully treated by embolization with detachable coils. A 72-year-old woman was admitted with complaint of bilateral leg weakness. Cervical magnetic resonance image showed compression of the spinal cord by a large vascular lesion. Right vertebral angiogram showed a vertebro-vertebral fistula draining into ectatic epidural veins. From a transfemoral arterial approach, the fistula site was selected with a microcatheter, and embolization was performed by placement of several Guglielmi detachable coils until flow arrest was obtained. The patient made a full recovery, and long-term angiographic follow-up demonstrated complete cure. We present a case of VVF treated using detachable coils with good long-term results.
