Ruptured Tentorial Arteriovenous Fistula: Endoscopic-Assisted Microsurgical Disconnection Using Indocyanine Green Videoangiography Guidance

Tentorial dural arteriovenous fistulas are rare causes of intracranial hemorrhage and nervous tissue venous congestion. Due to their extensive arterial supply and difficult transvenous endovascular navigation, they are frequently managed microsurgically. Precise identification of the venous drainage, its retractorless exposition, and real-time verification of arteriovenous disconnection are the mainstays of surgery. We describe the case of...
