A clinical analysis was made on seven patients of cerebral infarction localized in the territory of anterior cerebral artery (ACA). The incidence was 0.55% of whole 1283 cases of cerebral infarction. The pathogenesis of cerebral infarction of ACA territory was thought to be mainly due to the intracranial arteriosclerotic changes rather than the embolic mechanisms. The characteristics of clinical symptoms were hemiparesis with crural predominance, psychiatric symptoms and muteness at onset. Neurological recoveries were good in these patients. Two cases revealed disconnexion syndrome.
In two cases local cerebral blood flow measurements were done by use of stable Xenon and CT scanner, and local oligemia was noted not only in the ACA territory but also in the territory of the ipsilateral middle cerebral artery. From this evidence it was suggested that appeared symptoms in the acute stage were thought to be modified by such mechanism as intracranial redistribution of local cerebral blood flow.
