Results: the bloodflow in the normal vessels were laminar flow, the velocities were different in every stratum, the velocities were the fastest in the center and slow down towards the vessel wall.
Objective: To investigate the relationship of free radical, cerebral bloodflowvelocities and cerebral vasospasm (CVS) following subarachnoid hemorrhage (SAH).
前言： 目的：探讨自由基、脑血流速度与蛛网膜下腔出血后脑血管痉挛的关系。

Compare the decline in bloodflowvelocities and its recovery time before and after Trousseau's test in vertebral waveform with or without notch at systole.
