Endoscope-assisted supraorbital eyebrow approach for the treatment of ethmoidal dural arteriovenous fistula.

Ethmoidal DAVFs represent 10%-15% of all intracranial DAVFs. They are generally associated with a higher bleeding risk due to more malignant drainage characteristics and, regardless of a patient's symptoms, their treatment is highly recommended. Surgical disconnection has long been regarded as the gold-standard treatment for ethmoidal DAVFs, but several reports of successful endovascular treatments have been made. The authors present a case of a 65-year-old patient with an occasional finding of ethmoidal DAVF treated through an endoscope-assisted supraorbital eyebrow approach. In this video, they explain the radiographical, anatomical, and surgical considerations and demonstrate the surgical technique.
