Transcranial dopplerography (TDG) examination of the blood flow along the major intracranial arteries and cerebral vascular response to functional loads was performed in 51 patients with stenosis and/or occlusion of the internal carotid artery (ICA). The measurements were made on the equipment "Quantascope-103 PC" (Scimed, England). 74% (26 patients) of ICA occlusion subjects had asymmetry of the linear circulation rate (LCR) in the middle-size cerebral arteries (MCA). It occurred with LCR inhibition on the ipsilateral to the occlusion side. In half of ICA stenosis patients the ipsilateral MSA circulation was also reduced. The difference between the two groups in relation to MCA circulation asymmetry was significant (p < 0.001). Nitroglycerin and hypercapnia tests proved more informative than ortho- and antiorthostatic tests. A relationship was found out between overall stenosis of major brain arteries and blood flow along them.
对51例颈内动脉（ICA）狭窄和/或闭塞患者进行了经颅多普勒超声检查（TDG），以检测主要颅内动脉的血流情况以及脑血管对功能性负荷的反应。测量使用的设备是“Quantascope - 103 PC”（英国Scimed公司）。74%（26例）的ICA闭塞患者在大脑中动脉（MCA）出现线性循环速率（LCR）不对称，表现为闭塞侧同侧的LCR受抑制。在一半的ICA狭窄患者中，同侧大脑中动脉循环也减少。两组在MCA循环不对称方面的差异具有显著性（p < 0.001）。硝酸甘油和高碳酸血症试验比体位性试验更具信息量。发现大脑主要动脉的总体狭窄与其血流之间存在关联。
