Analysis on relative factors of traumatic subarachnoid hemorrhage

Objective:To explore and analyze the occurrence characteristics and related factors of traumatic subarachnoid hemorrhage (TSAH) in acute traumatic brain injury. Methods:In our department between March 2007 to October 2,009,326 inpatients of head injury (associated with complex injuries excluded) were retrospectively analyzed. According to admission CT scan results to determine TSAH.The patients were divided into TSAH group and non-TSAH group. The relation of TSAH with different age,gender,injury cause,GCS score,CT score,complicating primary brain injury and prognosis was studied. Results:The 147 cases of TSAH occurred (45.09%). With increasing age,TSAH was significantly increased. In the groups of 20 years of age and 20～60 year of age,the incidence were 17% and 66.6% respectively;car accident and falling from height were more common,accounting for 66.6% and 14.2% respectively. TSAH complicating brain injury was often brain contusion and subdural hematoma (48.7% and 42.9%);as the disease condition increase;TSAH significantly increased with poor prognosis. Conclusion:TSAH is common in the patients with acute traumatic brain injury. The more severe injuries,higher incidence and worse the prognosis.
