Abstract

Background: Cerebral vasospasm affects cerebral perfusion and causes secondary cerebral ischemia, increasing the risk of neurological sequelae and death. Objectives: The aim of the study was to determine the incidence of middle cerebral artery spasm in traumatic brain injury with subarachnoid haemorrhage by transcranial Doppler ultrasound, and its relationship with poor outcome. Material and Method: A prospective cohort study on the patients diagnosed with traumatic subarachnoid haemorrhage in the surgical intensive care unit at Gia Dinh People's Hospital from 12/2021 to 08/2022. Results: This study included 34 patients, 23 males (67,6%), 11 females (32,4%), median age was 45 year and the interquartile range was 29 – 67 years. Cerebral vasospasm occurred in 9 patients (26,5%). The rate of poor outcome in the group with middle cerebral artery spasm was 55,6% compared with 36,0% in the group without middle cerebral artery spasm, the difference was not statistically significant (p=0,44). Conclusion: Middle cerebral artery spasm is common in traumatic brain injury with subarachnoid haemorrhage. No association was found between presence of middle cerebral artery spasm and the risk of poor outcomes in traumatic brain injury with subarachnoid haemorrhage.
