Outcome of transarterial treatment of dural arteriovenous fistulas with direct or indirect cortical venous drainage

摘要

Background and purpose Transarterial Onyx embolization is an effective treatment for patients with intracranial dural arteriovenous fistula (DAVF). A study was performed to determine whether the clinical and radiological outcomes after transarterial Onyx treatment were affected by the type of cortical venous drainage (direct vs indirect) of high-grade DAVF.
