Lenticulostriate Stroke

Tuesday, September 1, 2015

A lenticulostriate stroke is a cerebral hemorrhage in the base of the brain, affecting the basal ganglia. This type of stroke occurs when one or two of the lenticulostriate arteries burst due to high blood pressure and/or an aneurism in one of these blood vessels, which are branches that arises from the medial cerebral artery. If the medial cerebral artery burst at a lower point before the emergence these branches, the blood supply to this brain area gets also interrupted, causing the death of millions of nerve cells. The lenticulostriate stroke is generally fatal because the basal ganglia are vital grey nuclei that connect the cerebral cortex with the pons and medulla oblongata.
