报道11例硬脑膜动静脉瘘,病因与静脉窦部分或全部狭窄、闭塞以及与外伤有关。颈外动脉供血为主,颈内动脉、椎动脉也可联合供血,引流也很复杂。全脑血管造影可确立诊断。手术结扎供血动脉可暂时缓解症状,但瘘口依然存在,很快复发。经血管内动脉联合静脉治疗,将微导管超选择送至近瘘口处,用不同的栓塞材料Ivalon、Coil、真丝微粒、线段、IBCA闭塞瘘口是较理想的治疗方法。Ivalon在AVF中弥散度较好,栓塞效果可靠。本组全部经血管内栓塞治疗,获满意效果。
Reported 11 cases of dural arteriovenous fistula, the cause of sinus and sinus some of all or all of the stenosis, occlusion and trauma related. External carotid artery blood supply, internal carotid artery, vertebral artery can also be combined with blood supply, drainage is also very complicated. Whole brain angiography can establish the diagnosis. Surgical ligation of the feeding artery can temporarily relieve symptoms, but the fistula still exists, and soon relapse. Transcatheter arterial and venous catheterization, the microcatheter sent to the fistula near the mouth, with different embolic material Ivalon, Coil, silk particles, line, IBCA occlusion fistula is an ideal treatment. Ivalon dispersion in the AVF better embolization effect. All of this group by endovascular embolization, satisfactory results.
