【 摘 要 】
Dural arteriovenous fistulas (DAVFs) may have aggressive symptoms, especially if there is direct cortical venous drainage. We report our preliminary experience in transarterial embolization of DAVFs with direct cortical venous drainage (CVR) using Onyx®. METHOD: Nine patients with DAVFs with direct cortical venous drainage were treated: eight type IV and one type III (Cognard). Treatment consisted of transarterial embolization using Onyx-18®. Immediate post treatment angiographies, clinical outcome and late follow-up angiographies were studied. RESULTS: Complete occlusion of the fistula was achieved in all patients with only one procedure and injection in only one arterial pedicle. On follow-up, eight patients became free from symptoms, one improved and no one deteriorated. Late angiographies showed no evidence of recurrent DAVF. CONCLUSION: We recommend that transarterial Onyx® embolization of DAVFs with direct cortical venous drainage be considered as a treatment option, while it showed to be feasible, safe and effective.
