In this report the authors describe a noninvasive transcranial method of determining the flow velocities in the basal cerebral arteries. Placement of the probe of a range-gated ultrasound Doppler instrument in the temporal area just above the zygomatic arch allowed the velocities in the middle cerebral artery (MCA) to be determined from the Doppler signals. The flow velocities in the proximal anterior (ACA) and posterior (PCA) cerebral arteries were also recorded at steady state and during test compression of the common carotid arteries. An investigation of 50 healthy subjects by this transcranial Doppler method revealed that the velocity in the MCA, ACA, and PCA was 62 +/- 12, 51 +/0 12, and 44 +/- 11 cm/sec, respectively. This method is of particular value for the detection of vasospasm following subarachnoid hemorrhage and for evaluating the cerebral circulation in occlusive disease of the carotid and vertebral arteries.
在本报告中，作者描述了一种用于测定脑基底动脉血流速度的无创经颅方法。将距离选通超声多普勒仪的探头置于颧弓上方的颞区，可根据多普勒信号测定大脑中动脉（MCA）的血流速度。还在稳态以及颈总动脉试验性压迫期间记录了大脑前动脉（ACA）近端和大脑后动脉（PCA）的血流速度。通过这种经颅多普勒方法对50名健康受试者进行的调查显示，MCA、ACA和PCA中的血流速度分别为62±12、51±12和44±11厘米/秒。该方法对于蛛网膜下腔出血后血管痉挛的检测以及评估颈动脉和椎动脉闭塞性疾病中的脑循环具有特殊价值。
