Anterolateral central arteries

As arteries centrales anterolateral (also: arteries lenticulostriatae ) several small arteries are summarized springing vertically from the middle cerebral artery, shortly after they emerged from the internal carotid artery.

Coverage area

After entry into the brain substance through the anterior perforated substance to supply the Aa. centrales anterolateral

  • Parts of the striatum and the pallidum
  • A small area of the thalamus
  • A large part of the internal capsule.

Pathology

Due to the unfavorable angle of departure of 90 ° from the middle cerebral artery and the resulting turbulence of blood flow can be found in this area particularly common arteriosclerotic changes in the vessel walls. If, by complete occlusion or rupture of a myocardial infarction or intracerebral hemorrhage, as indicated by reduced supply of the above structures, a paralysis of the contralateral half of the body ( hemiplegia ) results.
