Interventional treatment of dural arteriovenous fistula

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.
