Striate arteries

Striate arteries are small blood vessels that supply blood to the basal ganglia and internal capsule. They are also known as lenticulostriate arteries due to their location and the structures they supply.

Anatomy

Striate arteries arise from the middle cerebral artery (MCA). They are small, deep penetrating arteries that supply the basal ganglia and the internal capsule. The striate arteries are divided into lateral and medial groups. The lateral group supplies the putamen and the external segment of the globus pallidus, while the medial group supplies the caudate nucleus and the internal capsule.

Clinical significance

Due to their small size and deep location, striate arteries are susceptible to ischemic strokes, particularly in conditions such as hypertension. These strokes are often referred to as lacunar infarcts.
