Posterior Cerebral Circulation Stroke Secondary to Foetal Origin of Posterior Communicating Artery: an Indication for Carotid Endarterectomy

Posterior cerebral circulation strokes are most commonly caused by posterior vasculature in situ thrombosis, cardiac emboli, or arterial dissection. However, the foetal origin of the posterior communicating artery is an anatomical variant of the cerebral circulation that results in communication between the internal carotid and posterior cerebral circulation. This can, therefore, rarely result in posterior cerebral territory infarction from internal carotid artery thromboembolism. This is a report of a case in which a patient suffered posterior circulatory stroke secondary to this anatomical variation of the circle of Willis.
