The anterior cerebral artery (ACA ) supplies the medial part of the frontal and the parietal lobe and the anterior portion of the corpus callosum, basal ganglia and internal capsule.
It may be divided into segments :
A1 segment: from origin to anterior communicating artery and gives rise to medial lenticulostriate arteries. It supplies the inferior parts of the head of the caudate and the anterior limb of the internal capsule with the medial lenticulostriate arteries (Heubner's artery is the largest of the medial lenticulostriate arteries and supplies the anteromedial part of the head of the caudate and anterior inferior internal capsule).
A2 segment: from anterior communicating artery to bifurcation of pericallosal and callosomarginal arteries.
A3 segment: major branches and distal part of the ACA. It supplies the medial portions of frontal lobes, superior medial part of parietal lobes, anterior part of the corpus callosum.
Left-sided: mutism, transcortical motor aphasia, hemiparesis, left-arm apraxia and callosal disconnection syndromes
Right-sided: acute confusional state, hemiparesis, motor neglect
