Q9.
What are the key branches of the anterior cerebral artery (ACA) and their respective areas of supply?
Answer:
The anterior cerebral artery (ACA) has three main branches: the medial lenticulostriate branches, which supply the rostral portions of the basal ganglia; the pericallosal branches, which supply the corpus callosum; and the hemispheric branches, which supply the medial aspects of the frontal and parietal lobes. Key diagnostic features include infarcts in these areas leading to contralateral lower extremity weakness and behavioral changes. A common pitfall is mistaking ACA territory infarcts for motor neuron disease due to isolated leg weakness.
