Currently, the mainstay treatment of dural arteriovenous fistula (DAVF) involves endovascular approaches, especially for high-grade lesions. Transarterial embolization with preservation of venous sinuses has become the preferred approach due to the development of newer liquid embolic agents. For further precision during embolization, the use of temporary balloon occlusion to protect the patency of dural sinuses from the embolic agent's migration has been described.

A 64-year-old man presented with bilateral pulsatile tinnitus and visual decline. A diagnostic cerebral angiogram demonstrated a complex bilateral Borden type II and Cognard type IIB DAVF. Treatment was carried out endovascularly under general anesthesia in a staged fashion. In the first stage, the balloon was inflated during embolization to protect the right transverse sigmoid venous sinus system and torcula. In the second …
