Spinal Epidural AV Fistula Embolization with EVOH Copolymer Using the Scepter Mini Dual Lumen Balloon
Résumé
Left unattended, spinal epidural arteriovenous fistulas (EAVFs) have a potentially severe clinical course. Embolization using ethylene vinyl alcohol (EVOH) copolymers through regular dual-lumen balloons has emerged as a potential option for the treatment of spinal arteriovenous (AV) fistulas;1–3 the main issue with this technique is the navigability of these balloons. The Scepter Mini is a low-profile, dual-lumen balloon, which may be helpful for EVOH embolization of spinal AV fistulas, as it may help to overcome the navigation drawbacks. In this technical video, we present a case of EVOH embolization of a right T6 spinal EAVF through a Scepter Mini balloon. Of note, particular attention should be paid to radiculomedullary arteries arising at the same level or at adjacent levels to avoid severe neurologic complications related to uncontrolled migration of the liquid embolic agent. Moreover, excessive use of embolic material should be avoided to prevent spinal cord compression (video 1). Video 1
