硬脑膜动静脉瘘介入栓塞治疗

目的 探讨血管内栓塞治疗硬脑膜动静脉瘘(DAVF)的临床技巧与治疗效果.方法 收集珠江医院自2000年至2009年收治的DAVF患者50例,应用微导管技术,以各种不同材料在数字减影血管造影辅助下行血管内栓塞治疗,通过影像学检查及临床症状随访来评价临床疗效.结果术后即刻造影显示43例瘘口完全闭塞,6例瘘口绝大部份不显影,1例瘘口部分消失.随访6个月至7年,临床症状消失34例,症状明显缓解6例,复发7例,症状加重3例;无一例发生并发症.结论 应用微导管技术栓塞是治疗DAVF的有效手段,正确选择栓塞途径、材料和提高术者技术水平是治疗成功的关键.

Abstract：

Objective To explore the clinical skills and curative efficacy of endovascular embolization on dural arteriovenous fistula (DAVF). Methods A total of 50 patients with DAVF,admitted to our hospital from 2000 to 2009, underwent endovascular embolization with different materials through a microcatheter under DSA. After embolization, imaging examination was applied and clinical manifestations were noted during the clinical follow-up to evaluate the clinical efficacies.Results Immediate postoperative angiography indicated that the fistulas were totally occluded in 43patients, occluded evidently in 6 and occluded partially in 1. The 6-84 months follow-up found that clinical symptoms of 34 patients disappeared, 6 alleviated evidently, 7 relapsed, and 3 worsened; no complications were noted. Conclusion The endovascular embolization for DAVF is effective; and choosing the right embolic approach and material and improving the technology are the keys of successful treatment.
