[Infarction of the anterior choroidal territory. Clinical and tomodensitometric study of 11 cases]

Clinical features of anterior choroidal artery (ACA) territory infarct are hemiplegia, hemi-anaesthesia and homonymous hemianopia. However this syndrome in its complete form is of rare occurrence, since one or more signs or symptoms may be lacking. The Authors describe 11 patients with CT-documented infarctions in the (ACA) territory in order to establish clinical-CT correlations and possible risk factors. Among the investigated risk factors arterial hypertension is the most frequent in these patients. This finding, and the small size of the ischemic lesions make the ACA territory infarctions similar to Lacunar Infarcts. The Authors, emphasize that, as in lacunar infarcts, a thromboembolic mechanism cannot always be ruled out in ACA infarctions. Therefore a cause other than arterial hypertension should be considered in each patient for a better management of this type of infarcts.
