E-172 Gamma knife radiosurgery as treatment of bilateral dural arteriovenous fistulas: a case report

Abstract

different microcatheters such as the Prowler EX and Select Plus (Cerenovus), Phenom 21 and 27 (Medtronic), Via 17 and 33 (Microvention), Trevo Pro 18 and Excelsior SL-10 (Stryker), over a Glidewire 0.035-inch in one case and over the Tenzing 7 insert catheter (Route 92) in 2 cases. The most distal vessel in which the tip of the Esperance catheter was placed was the petrous ICA (n=1), cavernous ICA (n=5), ICA terminus/communicating segment (n=2), M2/MCA (n=1), V3 segment (n=2), basilar artery (n=2), Internal maxillary artery (n=1) and transverse sinus (n=1). The catheter offered the desired support in all cases. The catheter was never exchanged due to lack of support and/or inability to perform the procedure. No catheter related complications occurred. Conclusion The Esperance catheter is a new device in the neurointerventional toolbox. It can be safely and successfully used for a variety of procedures. Disclosures A.
