Arteriae centrales anterolaterales

As anterolateral central arteries (also: arteries lenticulostriatae) several small arteries are summarized perpendicular from the middle cerebral artery , shortly after they exit the spring internal carotid artery emerged.

Coverage area

After entering the brain matter through the substantia perforata anterior, supply the Aa. centrales anterolaterales

• Parts of the striatum as well as the pallidum
• a small area of ​​the thalamus
• a large part of the internal capsule .

pathology

Due to the unfavorable exit angle of 90 ° from the A. cerebri media and the resulting turbulence of the blood flow , changes in the vessel walls caused by arteriosclerosis are particularly common in this area . If an infarct or intracerebral hemorrhage occurs as a result of complete occlusion or rupture, this results in paralysis of the contralateral half of the body ( hemiplegia ) due to insufficient supply of the above-mentioned structures .
