脑血管痉挛(CV S)是继发于脑外伤后的常见严重并发症,常最终致残或死亡。但CV S还未受到临床医生和研究者的重视[1]。脑血流循环障碍是导致继发性颅脑损伤重要的病理生理基础之一,因此针对颅脑损伤后脑血流循环状态的监测具有重要的治疗意义[2]。我们重点从脑循环动力学监测角 Cerebral vasospasm (CVS) is a common and serious complication secondary to traumatic brain injury, often eventually causing disability or death. But CVS has not been the attention of clinicians and researchers [1]. Cerebral blood flow circulatory disturbance is one of the important pathophysiological basis of secondary craniocerebral injury. Therefore, the monitoring of cerebral blood flow circulation after craniocerebral injury has an important therapeutic significance [2]. We focus on the monitoring of cerebral circulation dynamics
