[Neuropsychological approach to detecting the anterior, middle and posterior cerebral artery "steal" syndromes].

Neuropsychological symptoms of "robbing" the anterior, median, and posterior cerebral arteries due to the ischemia caused within their basins by arteriovenous aneurisms were studied. The disappearance of the "robbing" symptoms after occluding the influx vessels of the aneurism by a separable balloon-catheter (62 observations), or after radical excision of the arteriovenous aneurism (81 observations) was taken for the control. The dynamics of the "robbing" symptoms in the process of the endovascular operations was followed. The importance of the "robbing" and the local symptoms associated with the localization of the vascular conglomerate for the clinic of arteriovenous aneurisms is demonstrated. A high sensitivity of the neuropsychological tests to changes of the cerebral hemodynamics is noted.
