Internal Carotid Artery
Supplies blood to most of the medial surface of the cerebral cortex ( anterior three fourths ), frontal pole ( via cortical branches ), and anterior portions of the corpus callosum. Perforating branches ( including the recurrent artery of Heubner and Medial Lenticulostriate Arteries ) supply the anterior limb of the internal capsule, the inferior portions of head of the caudate and anterior globus pallidus. Blockage Affects: Bilateral occlusion of Anterior Cerebral Arteries at their stems results in infarction of the anteromedial surface of the cerebral hemispheres:
Unilateral occlusion (distal to Ant. Comm. origin) of Anterior Cerebral Artery produces contralateral sensorimotor deficits mainly involving the lower extremity with sparing of face and hands. |
