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.
I型髓周脊髓动静脉瘘(AVF)的栓塞可能具有挑战性,这是由于供血动脉迂曲、直径小以及瘘口位置偏远。在我们机构,1.5F血流导向导管结合亲水导丝已被用于使用氰基丙烯酸酯胶栓塞脊髓血管畸形的瘘口。这种组合提高了我们实现瘘口超选择性插管的成功率。因此,5例I型髓周AVF患者中有4例可通过该技术治愈。与II型和III型髓周AVF一样,血管内治疗方法也可能是I型髓周脊髓AVF的一线治疗方法。
