외상성 뇌손상 환자에서 기저핵 출혈의 임상 양상과 예후

초록

Objective To assess the frequency of traumatic basal ganglia hemorrhage (TBGH) and its functional recovery in traumatic brain injury (TBI). Method Three hundred two patients with TBI were retrospectively analyzed via the medical records and radiologic findings. The subjects were divided into 4 groups according to the brain lesions: extraaxial lesion (subdural hemorrhage, epidural hemorrhage, subarachnoid hemorrhage), intraaxial lesion (diffuse axonal injury, white matter hemorrhage, gray matter hemorrhage), mixed lesion, and TBGH. Statistical comparison of cause, severity and prognosis between groups was performed wth Chi-square analysis. Results Mean age was 41.6 years old. The most common lesion of TBI was extraaxial lesion. The most common cause was falls (47.5%). The incidence of TBGH group was 4.7%. Although TBGH group was of longer duration of hospital stay and lower GCS than the other brain lesions, there was no significant difference in GOS score. TBGH with extraaxial or mixed lesion was of lower GCS and GOS score compared with TBGH itself or TBGH with intraaxial lesion. Conclusion The associated cerebral lesion, but not TBGH itself, could be considered to be an important factor in determining severity and recovery of TBI.
