Manual aspiration thrombectomy for basilar infarction in the setting of a persistent primitive hypoglossal artery: Case report and review of the literature

摘要

Background:Persistent primitive hypoglossal artery (PPHA), a remnant of embryonal circulation, is a rare variant of the posterior cerebral circulation. Seven prior cases of posterior circulation stroke in the setting of PPHA have been described in the literature, with all but one case being attributable to atherosclerotic embolization from the internal carotid artery (ICA) through the PPHA.
