"Spectrum of anterior cerebral artery territory infarction: clinical and MRI findings". Anterior cerebral artery syndrome is a condition whereby the blood supply from the anterior cerebral artery (ACA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the medial aspects of the frontal and parietal lobes, basal ganglia, anterior fornix and anterior corpus callosum.. The middle cerebral artery (MCA) can be divided into 4 segments: the M1 (horizontal segment) extends to the anterior basal portion of the insular cortex (the … The anterior cerebral artery (ACA) arises from the internal carotid, at the medial extremity of the lateral cerebral fissure. The cerebellum is also supplied by three arteries. There was no neurological deficit on presentation. This risk may be increased in sporadic patients with an incomplete circle of Willis, a normal anatomic variant. (2) Anterior cerebral artery.
