definition

The middle cerebral artery (MCA) is also designated the Sylvian artery, from Jacques Dubois, known as Jacobus Sylvius (1489–1555), a linguist and anatomist in Paris. The artery is subdivided into the M1 segment, from which start the deep perforating lenticulostriate arteries, the M2 segment, corresponding to the segment after the bifurcation into superior and inferior divisions, and the M3 segment, including the insular part. The M4 segments, the leptomeningeal arteries, arise from the M3 segments and are named orbitofrontal, prefrontal, precentral, central sulcus, anterior parietal, posterior parietal, angular and temporal arteries, with important variations in their territories. The MCA territory is the one most frequently affected by acute strokes. MCA territory infarcts can be subtle or a devastating clinical syndrome, depending on the site of the occlusion, the extent of ischemia, the etiology, and the collateral arterial network. As collateral networks are highly variable, an occlusion of the same artery at the same place may lead to quite variable severity of the stroke and of prognosis. Large infarcts are defined as involvement of two of the three MCA territories (deep, superior and inferior divisions) and “malignant MCA stroke” as complete or near complete MCA territory infarction with ensuing mass effect from brain edema.
