title: Microsurgical obliteration of a thoracic spinal perimedullary arteriovenous fistula.
abstract: Spinal vascular lesions are rare and may be classified as a) dural arteriovenous fistulas (AVFs), b) arteriovenous malformations, or c) perimedullary AVFs. In this narrated video illustration, we present the case of a 71-year-old woman who presented with progressive bilateral lower extremity weakness and urinary retention who was diagnosed with a thoracic spinal perimedullary arteriovenous fistula. The diagnostic studies included a thoracic MRI and spinal angiogram. A multilevel thoracic laminoplasty was performed for microsurgical obliteration of the AVF. The techniques of intraoperative angiography, thoracic laminoplasty and microsurgical obliteration and resection of the AVF are reviewed. The video can be found here: http://youtu.be/5vVp3oq5sLg.
