Case ReportsEndovascular embolization of carotid-cavernous fistula using the posterior communicating artery approach: a case report.
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. ⋯ 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.
