Acute middle cerebral artery stroke in a patient with a patent middle cerebral artery.

Abstract

Knowledge of cerebrovascular anatomical variants is vital for clinicians working with patients presenting with signs and symptoms of cerebral infarction, particularly in the era of endovascular clot retrieval. We provide an overview of a cerebrovascular anatomical variation and detail a patient presenting with cerebral infarction secondary to occlusion of their anomalous vessel who underwent successful endovascular clot retrieval with excellent functional outcome. We also include technical descriptions. Given the clinical importance of the areas supplied by the accessory middle cerebral artery, knowledge of this vessel is not only important for diagnosis but also for neurosurgical or endovascular management of patients with this variant.
