title: Endovascular embolization of carotid-cavernous fistula using the posterior communicating artery approach: a case report.
abstract: We report a case of direct carotid-cavernous fistula complicated with occlusion of internal carotid artery (ICA) at attempted endovascular obliteration via ICA and subsequent successful embolization via the posterior communicating artery (PCoA) approach. After a thorough understanding of vascular anatomical alterations associated with initial technical failure with detachable balloons, a microcatheter was navigated to the fistula site via the vertebro-basilar-PCoA to the distal cavernous segment of the left ICA. Embolization of the fistula was performed with deposition of three platinum microcoils. Angiograms after embolization showed complete disappearance of the fistula. There was no procedural complication and no recurrence of fistula at one-year clinical follow up.
