Bilateral anterior cerebral artery coarctation means that the blood supply of both anterior cerebral arteries comes from the same blood vessel, which is a congenital developmental abnormality and there is no way to treat it. However, patients must control the risk factors of cerebrovascular disease to avoid cerebral infarction and other diseases, because if the blood vessels supplying the bilateral anterior cerebral arteries have problems, it will cause the blood in the areas supplied by the bilateral anterior cerebral arteries, such as the frontal, temporal, parietal and basal ganglia, which will lead to necrosis in these areas and manifest as hemiparesis, sensory impairment and aphasia of the limbs. Risk factors should be prevented by giving anti-platelet aggregation, complete and strict control of blood pressure, blood sugar and lipid control.
