The middle cerebral artery
(MCA) is a branch of the internal carotid artery
. There is then one on each side of the brain. They are found in the lateral fissure of Sylvius, a trough which separates the lobes of the brain. MCAs enable blood
to reach the deeper, and more superficial, areas of the brain, in particular a large part of the surface of the hemispheres. In the case of the obstruction of the MCA, it is a sylvian infarction
which is the consequence of brain failure, responsible for the symptoms of stroke
: the main signs of stroke
in this area are major or minor hemiplegia
, or specific vision problems.
