Treatment of slow-flow (type I) perimedullary spinal arteriovenous fistulas with special reference to embolization.
Embolization of type I perimedullary spinal arteriovenous fistulas (AVFs) can be difficult, because of tortuosity and the small diameter of the feeder and distal location of the fistula site. The 1.5F flow-directed catheter in conjunction with a hydrophilic guidewire has been used in fistula embolization with cyanoacrylate glue for spinal vascular malformations at our institution. This combination has improved our success rate in achieving superselective catheterization of the fistula. Thus, 4 of 5 patients with type I perimedullary AVFs could be cured with this technique. Like type II and type III perimedullary AVFs, the endovascular approach may also be the first line of treatment in type I perimedullary spinal AVF.
