The diagnostic and therapeutic experience of cerebral vasospasm after traumatic brain injury

Abstract

Objective To observe the detection methods of cerebral vasospasm after traumatic brain injury and the impact on prognosis.Methods Twenty patients with traumatic brain injury underwent transcranial Doppler ultrasound were divided into cerebral vasospasm group and control group.Results There were 7 patients combined with cerebral vasospasm and 13 patients without cerebral vasospasm.Two patients died in cerebral vasospasm group and 1 patient died in control group.The fatality rate between two groups had significant difference (P ＜0.05).All surviving patients followed up for 1 year after being discharged.According to the Glasgow Outcome Scale,in cerebral vasospasm group,3 patients were with severe disability,1 patient was with moderate disability,1 patient restored good function.In control group,2 patients were with severe disability,2 patients were with moderate disability,8 patients restored good function.The rate of restored good function between two groups had significant differences (P ＜ 0.05).Conclusions Cerebral vasospasm can increase mortality in traumatic brain injury patients,and the functional evaluation in survival patients are even worse.Prevention of cerebral vasospasm after traumatic brain injury has important clinical significance.
