Middle Cerebral Artery Stroke

Abstract

The middle cerebral artery (MCA) is the most common artery involved in acute stroke. It branches directly from the internal carotid artery and consists of four main branches, M1, M2, M3, and M4. These vessels provide blood supply to parts of the frontal, temporal, and parietal lobes of the brain, as well as deeper structures, including the caudate, internal capsule, and thalamus. Its vast supply means that strokes involving the MCA territory can have a multitude of presenting symptoms, depending on which branches and structures are affected.
