Study of Risk Factors for Hematoma Enlargement Following Traumatic Acute Intracranial Hemorrhage

ObjectiveTo explore the hematoma enlargement risk factors after traumatic acute intracranial hemorrhage.Ninty-three patients of head injury with acute intracranial hemorrage were observed by CT scanning. The patients were divied into hematoma enlargement and non-enlargement group. Univariate and multivariate analyses were used to explore the hematoma enlargement risk factors.Single factor analysis identified the following risk factors:age60,interval between the injury and primary CT within 1h,hypertension,long term drinking wine ,intracerebral irregular shape hemorrhage and hamatoma volume ≥20 ml were associated with hematoma enlargemant(P0.05). In Logistic regression significant associations with hematoma enlargement were coagulation disorder(OR=7.25,95%CI=3.812~14.173)and intracerebral multifocal hemorrhage(OR=2.56,95%CI=1.095~5.994).[Conclusion]Besieds single factor analysis significant for hematoma enlargement,coagulation disorder and intracerebral multifocal hemorrhage are also the main risk factors for hematoma enlargement.
