Risk Factors for Reoperation after Traumatic Intracranial Hemorrhage / 대한신경손상학회지

ABSTRACT

OBJECTIVE: Progression after operation in traumatic brain injury (TBI) is often correlated with morbidity and poor outcome. We have investigated to characterize the natural course of traumatic intracranial hemorrhage and to identify the risk factors for postoperative progression in TBI. METHODS: 36 patients requiring reoperation due to hemorrhagic progression following surgery for traumatic intracranial hemorrhage were identified in a retrospective review of 335 patients treated at our hospital between 2001 and 2010. We reviewed the age, sex, Glasgow Coma Scale, the amount of hemorrhage, the type of hemorrhage, rebleeding site, coagulation profiles, and so on. Univariate statistics were used to examine the relationship between the risk factors and reoperation. RESULTS: Acute subdural hematoma was the most common initial lesion requiring reoperation. Most patients had a reoperation within 24-48 hours after operation. Peri-lesional edema (p=0.002), and initial volume of hematoma (p=0.013) were the possible factors of hemorrhagic progression requiring reoperation. But preoperative coagulopathy was not risk factor of hemorrhagic progression requiring reoperation. CONCLUSION: Peri-lesional edema and initial volume of hematoma were the statistical significant factors requiring reoperation. Close observation with prompt management is needed to improve the outcome even in patient without coagulopathy.
