De Novo Aneurysm after the Intravascular Surgery for Traumatic CCF with Contralateral Ocular Symptoms

Abstract

We report a case of a posttraumatic carotid cavernous fistula (CCF) with contralateral ocular symptoms. Angiography revealed a fistula to the contralateral cavernous sinus via the intercavernous sinus. We successfully treated the CCF with a Guglielmi detachable coil. However 2 months later the patient suffered from subarachnoid hemorrhaging due to a newly formed aneurysm of the left middle cerebral artery. It was suggested that this new de novo aneurysm was formed by the hemodynamic stress following the coil occlusion of the cavernous fistula.
