The middle cerebral artery MCA is one of the three major paired arteries that supply blood to the brainThe MCA arises from the internal carotid artery as the larger of the two main terminal branches the other being the anterior cerebral artery coursing laterally into the lateral sulcus where it branches to perfuse the cerebral cortex. Infarction of the ventral posterior lateral VPL and ventral medial nuclei VPM supplied by thalamoperforators from the posterior cerebral artery.

The Journal of Stroke Cerebrovascular Diseases publishes original papers on basic and clinical science related to the fields of stroke and cerebrovascular diseases. Its role is to provide blood supply to the brain. This artery may form an anastomosis with the posterior cerebral artery.
The middle cerebral artery is one of the most widely recognized arteries that is involved in large vessel strokes. Posterior circulation stroke syndrome POCS refers to the symptoms of a patient who clinically appears to have had a posterior circulation infarct but who has not yet had any diagnostic imaging eg. Acute ischemic stroke is caused by thrombotic or embolic occlusion of a cerebral artery and is more common than hemorrhagic stroke.
Both circulations are connected by the posterior communicating. This artery in turn branches into the medial frontal arteries anterior intermediate posterior and the paracentral artery with the cingulate branches arising throughout its length. The Editors of Clinical Imaging in conjunction with the Elsevier Office of Continuing Medical Education are pleased to offer an AMA PRA Category 1 CME credit program for registered Clinical Imaging physician reviewers who complete manuscript reviews.
The MCA is the cerebral artery that is most often occluded and its large area of supply means that a stroke to this artery can be devastating. This happens because of either blockage of a blood vessel or bleeding of a blood vessel in the brain. Anterior and posterior circulations provide the primary blood circulation of the brain.
