Staged Endovascular Occlusion of a Posterior Communicating Artery-Cavernous Sinus Fistula and a Basilar Artery-Cavernous Sinus Fistula Associated with Traumatic Pseudoaneurysms: Technical Consideration and Literature Review

Abstract

Background: Traumatic injury of the posterior communicating artery or the basilar artery causing arteriovenous fistulae is rare.

Case description: Here we report an unusual case of the coincidence of a posterior communicating artery-cavernous sinus fistula and a basilar artery-cavernous sinus fistula associated with traumatic pseudoaneurysms of the posterior communicating and basilar arteries. The fistulas and pseudoaneurysms were obliterated completely after staged endovascular surgery via a transarterial and transvenous route.

Conclusions: To our knowledge, this is the first such report worldwide.
