title: Successful management of an anterior thoracic Type IV spinal arteriovenous malformation with two associated aneurysms utilizing vertebrectomy. Technical note.
abstract: Anteriorly located Type IV thoracic arteriovenous malformations (AVMs) are difficult to treat surgically. Although high-flow fistula subtypes are amenable to treatment using endovascular techniques, low-flow fistulas should be treated surgically. There are few reports discussing the diagnosis, behavior, and treatment of these spinal fistulas due to their low incidence. Posterior surgical approaches to Type IV spinal AVMs reported in the literature have been associated with high morbidity rates or aborted procedures. The authors report the successful management of a T-12 Type IV spinal AVM with an emphasis on approach, interoperative angiography, and the use of modern instrumentation. To the authors' knowledge, this is also the first reported case of multiple arterial-side aneurysms in a Type IV AVM of the anterior spinal artery.
