Anatomical safety and precaution of transarterial embolization of a falcotentorial dural arteriovenous fistula fed by the artery of Davidoff and Schechter: Case report and review of the literature

Abstract

The artery of Davidoff and Schechter (ADS), a pure meningeal branch of the posterior cerebral artery (PCA), is often reported as a feeder of the tentorial dural arteriovenous fistula (TDAVF). However, there are few reported cases of embolization via this artery. We present an interesting case of a patient with incidentally found TDAVF fed by the ADS and with fetal type posterior communicating artery, in which the feeder was confused with the PCA due to the similar pathways around the brain stem. It was successfully treated with transarterial embolization through the ADS. We reviewed related published articles to determine the safety of embolization via the ADS.
