Fifty atherosclerotic patients with chronic disorders of the cerebral blood circulation (CDCBC) were involved in this study of both systemic hemodynamics (by diluting Evans blue) and rheoencephalographic parameters of the cerebral circulation with regard to the stage of the CDCBC. Compensated vascular-cerebral insufficiency was associated with a significant rise in the arterial pressure, acceleration of the blood flow in the hand-ear region and with an increase in the heart rate. Visual and amplitude-frequency characteristics of REGs in a compensatory stage of the CDCBC deepened only slightly; in a remitting stage they deepened significantly in the left carotid and vertebral-basal basins; in a subcompensated stage, in both basins bilaterally; and in a decompensated stage, predominantly in the carotid basin.
五十名患有慢性脑血液循环障碍（CDCBC）的动脉粥样硬化患者参与了这项关于全身血流动力学（通过伊文思蓝稀释法）以及脑循环的脑血流图参数与CDCBC阶段关系的研究。代偿性血管性脑供血不足与动脉压显著升高、手耳区域血流加速以及心率增加有关。在CDCBC代偿期，脑血流图的视觉和振幅频率特征仅略有加深；在缓解期，左颈动脉和椎基底动脉流域显著加深；在亚代偿期，双侧流域均加深；而在失代偿期，主要在颈动脉流域加深。
