Analysis of the Efficacy and Prognosis of Microsurgery and Transarterial Embolization in the Treatment of High-Grade Dural Arteriovenous Fistulas.

ABSTRACT:

Objective

To evaluate the surgical outcomes of microsurgical treatment and transarterial endovascular embolization for dural arteriovenous fistulas (DAVFs).

Methods

A retrospective analysis was conducted on 47 patients diagnosed with high-grade DAVFs (Cognard types 2b, 2a + b, 3, 4, and 5) between June 2019 and June 2022 at Nanjing Brain Hospital, affiliated with Nanjing Medical University. These patients underwent either microsurgery or endovascular embolization. Postoperative efficacy, surgical complications, and related prognostic factors were compared between the two groups. The primary endpoint was a postoperative modified Rankin Scale (mRS) score > 3. Secondary outcomes included angiographic confirmation of fistula occlusion, complication rates, and neurological defici
