目的

评价血管内栓塞治疗硬脑膜动静脉瘘（DAVF）的治疗效果。

方法

2005—2013年收治DAVF患者30例，行血管内栓塞治疗。根据手术成功率、围手术期并发症、随访结果评价疗效。

结果

术后即刻造影显示治愈18例（60%），好转11例（36.7%），无效1例（3.3%）。随访（14.4±11.0）个月后，29例患者症状缓解或消失。10例行脑血管造影随访，造影随访时间为（12.5±8.8）个月，8例治愈，2例有少量残余。

结论

血管内栓塞是治疗DAVF安全有效的方法。对于海绵窦区DAVF，经静脉途径栓塞可以取得满意疗效。对于非海绵窦区DAVF，应用Onyx经动脉入路栓塞可以取得满意的疗效。

Objective

To evaluate angiographic and clinical results in patients with a dural arteriovenous fistula（DAVF）who underwent endovascular embolization.

Methods

During the period from 2005 to 2013，a total of 30 patients with DAVF were treated with endovascular embolization.The technical success rate，perioperative complication and follow-up results were recorded and analyzed.

Results

The initial angiographic results showed complete occlusion of arteriovenous fistula in 18 cases（60%），partial occlusion in 11 cases（36.7%），no change in 1 case（3.3%）.All patients were available for follow-up（14.4±11.0）months.The clinical follow-up findings demonstrated full recovery or symptom improvement in 29 patients.The angiographic follow-up（（12.5±8.8）months）was performed in 10 cases，and showed complete occlusion of fistula in 8 cases，partial occlusion in 2 cases.

Conclusions

Endovascular embolization is an efficient treatment for DAVF.Transvenous embolization is a highly efficient treatment in dural carotid-cavernous sinus fistula.It is safe and effective to embolize the DAVF of the non-carotidcavernous sinus through transarterial approach with Onyx.
