Abstract

Carotid-cavernous fistulas (CCFs) are vascular shunts that allow blood to flow from the carotid artery or its branches into the cavernous sinus. Endovascular embolization is the treatment modality of choice. The trigeminocardiac reflex (TCR) is a vagally mediated reflex that can lead to hemodynamic instability. It can be activated during embolization procedures due to the proximity of vagal efferent neurovascular structures within the cavernous sinus. This case report describes the intraoperative management of recurrent, profound bradycardia due to TCR during endovascular CCF embolization.
