目的：评估经动脉颗粒栓塞颈外动脉供血型硬膜动静脉瘘的应用技术和临床效果。材料和方法：１０例经血管造影证实的硬膜动静脉瘘患者，选择性插管入近病巢处的供养动脉或近供养动脉开口的主干动脉，在电视严密监视下缓慢注入ＰＶＡ颗粒直至血流静止、瘘道闭塞。术后１５分钟和６个月随访血管造影及评估临床情况。结果：７例术后瘘道完全闭塞，３例大部闭塞（８０％发以上），６个月后随访血管造影者７例，均未显示瘘道。结论：经动脉采用颗粒栓塞颈外动脉供血型硬膜动静脉瘘，其操作简便，较为安全，临床效果好，应视为此类疾病的首选治疗方法。
OBJECTIVE: To evaluate the application and clinical efficacy of arterial embolization of external carotid artery supplying arteriovenous fistula. Materials and Methods: Ten cases of dural arteriovenous fistula confirmed by angiography were selectively intubated into the feeding artery near the nests of the nests or the main artery near the opening of the feeding artery. PVA particles were infused slowly under the close surveillance of the TV until blood Flow still, fistula occlusion. Follow-up angiography at 15 minutes and 6 months after surgery and evaluation of clinical conditions. Results: Seven cases of postoperative fistula occlusion, occlusion of most of the three cases (80% or more), 6 months after angiography in 7 cases, no fistula. Conclusion: Particle embolization of external carotid artery dural arteriovenous fistula via arterial embolization is simple and safe, and has good clinical effect. It should be regarded as the first choice of treatment for such diseases.
