What is the meaning of Striate artery?

The striate arteries are a collection of small, penetrating arteries arising from the anterior and middle cerebral arteries that supply blood flow to the deep structures of the cerebral hemispheres, including the basal ganglia and internal capsule.

What are the symptoms of infarction in the territory of left Lenticulostriate artery?

The clinical aspects of lenticulostriate infarction should be properly differentiated from those of other anterior circulation infarcts. Clinical signs include motor deficit, sensory deficit and cognitive dysfunction.

What is Heubner’s artery?

Recurrent artery of Heubner, also known as the medial striate artery or long central artery, is the largest perforating branch from the proximal anterior cerebral artery (ACA) and is the only one routinely seen on angiography.

What does the lateral striate arteries supply?

The lateral lenticulostriate arteries arise from the proximal middle cerebral artery (MCA), usually from M1 segment, more rarely from the postbifurcation or M2 segment. They supply the lateral portion of the putamen and external capsule as well as the upper internal capsule.

What does the medial striate artery supply?

The medial striate artery is a very small artery that branches off the anterior cerebral artery just rostral to the formation of the anterior communicating artery. Branches of the medial striate artery supply the rostromedial aspects of the caudate, lenticular nucleus, and anterior limb of the internal capsule.

Where do Lenticulostriate arteries arise from?

The lenticulostriate arteries, also known as anterolateral central arteries, are a collection of small perforating arteries arising from the anterior part of the circle of Willis and supplying the basal ganglia.

What causes infarction?

Infarction is tissue death or necrosis due to inadequate blood supply to the affected area. It may be caused by artery blockage, rupture, mechanical compression, or vasoconstriction.

What does the medial Striate supply?

What is Faciobrachial paresis?

Faciobrachial monoparesis is presumed to be secondary to lesions involving Heubner artery( a proximal perforating branch from anterior cerebral artery ) or lateral lenticulostriate artery(branch of middle cerebral artery). Here we report a case of faciobrachial monoparesis secondary to borderzone infarcts.
