Spinal dural arteriovenous fistulas (sDAVF) are the most common spinal vascular lesions. The arterialization of the recipient vein results in venous hypertension and chronic ischemia. Intravascular injection of acrylic glue in order to occlude the draining vein is the principle of endovascular treatment, but a significant portion of embolization procedures do not succeed. We present our initial experience of endovascular balloon augmented embolization of sDAVF using a dual-lumen balloon.
Three patients harboring sDAVF were submitted to endovascular treatment by onyx injection assisted by a double-lumen balloon as the sole therapy. Control angiography demonstrated complete obliteration of the fistula in all cases with clinical improvement.
Dual-lumen balloon onyx embolization of spinal dural arteriovenous fistulas appears to be an acceptable and feasible alternative.
硬脊膜动静脉瘘（sDAVF）是最常见的脊髓血管病变。接受静脉的动脉化导致静脉高压和慢性缺血。向引流静脉内注射丙烯酸胶以闭塞静脉是血管内治疗的原则，但很大一部分栓塞程序并未成功。我们介绍了使用双腔球囊对 sDAVF 进行血管内球囊增强栓塞的初步经验。
3 名患有 sDAVF 的患者接受了经双腔球囊辅助的血管内 ONYX 注射治疗，这是唯一的治疗方法。控制血管造影显示所有病例均完全闭塞瘘口，临床症状改善。
双腔球囊 ONYX 栓塞治疗脊髓硬脊膜动静脉瘘似乎是一种可接受且可行的替代方法。
