Microsurgical treatment of spinal dural arteriovenous fistula with subarachnoid hemorrhage: a case report.

Abstract

A rare spinal vascular malformation, the spinal dural arteriovenous fistula (sDAVF), is characterized by subtle clinical signs that make diagnosis and treatment of it highly challenging. In this case, we report a 70-year-old male who presented with subarachnoid hemorrhage, an unusual initial symptom of sDAVF. This report emphasizes the diagnostic complexities and highlights a successful management approach utilizing intraoperative indocyanine green angiography. Early identification and precise localization via advanced imaging techniques were pivotal in achieving a favorable outcome.
