Abstract
Objective To analyze the risk factors of cerebral vasospasm following operation for acoustic neuroma. Methods From January 2010 to February 2015, 153 patients received acoustic neuroma operation via retrosigmoid approach in our hospital. According to inclusion and exclusion criteria, a retrospective analysis was performed on 80 patients who met the requirements. According to the flow velocity and spectra of the vertebrobasilar artery, internal carotid artery, middle cerebral artery and anterior cerebral artery monitored by transcranial Doppler before operation and on the 1st, 3rd, 5th, 7th and 9th day after operation, the 80 patients were divided into vasospasm group (43 cases) and non-vasospasm group (37 cases). General data and clinical indexes of the two groups were analyzed. Multivariate logistic regression analyses were conducted to investigate the risk factors of cerebral vasospasm following operation for acoustic neuroma. Results There were significant differences in age, the maximum tumor diameter, tumor texture and adhesion to the trigeminal nerve or brain stem between the two groups (P<0.05). Younger age, larger tumor and firm tumor consistency were the risk factors of vasospasm (P<0.05). Conclusions Younger age, larger tumor and firm tumor consistency are the risk factors of cerebral vasospasm.关键词
