Ultrasonic dopplerography and rheoencephalography were employed to investigate cerebral circulation in patients (n-123) with carotid artery atherosclerosis having transient disturbances of cerebral circulation or ischemic apoplexy. The ischemic foci were measured and localized at computed and NMR tomography. The above complex of examinations allowed evaluation of local, regional and overall blood filling of the brain, of collateral flow as well as conclusion on the type of cerebral hemodynamics. Focal lesions seem to arise in inadequate functioning of collateral circulation, that is in patients with unstable and decompensated hemodynamics. Active collateral circulation shown by the absence of noticeable interhemispheric asymmetry proved prognostically favourable. Administration of vasoactive drugs to patients with decompensated cerebral hemodynamics may induce stealing syndrome and aggravation of neurological symptoms.
采用超声多普勒成像和脑血流图对123例有短暂性脑循环障碍或缺血性中风的颈动脉粥样硬化患者的脑循环进行了研究。通过计算机断层扫描和核磁共振断层扫描测量并定位缺血灶。上述一系列检查能够评估脑的局部、区域和整体血液灌注情况、侧支循环情况以及得出脑血流动力学类型的结论。局灶性病变似乎是由于侧支循环功能不全所致，即在血流动力学不稳定和失代偿的患者中出现。无明显半球间不对称所显示的活跃侧支循环在预后方面被证明是有利的。对脑血流动力学失代偿的患者使用血管活性药物可能会诱发盗血综合征并加重神经症状。
