目的分析重型颅脑损伤继发外伤性癫形成的原因、发病机制,以及外伤性癫的预防措施。方法对重型颅脑损伤患者救治过程中继发外伤性癫的临床特点和治疗结果进行回顾分析。结果 946例重型颅脑损伤病人继发性癫103例,发生率10.9%。其中颅骨凹陷粉碎性骨折39例(37.9%),开放性颅脑损伤28例(27.2%),颅内血肿25例(24.3%),单纯脑挫裂伤11例(10.7%)。结论重型颅脑损伤继发外伤性癫是局部严重的脑神经细胞结构损伤和神经抑制、负反馈系统破坏,导致神经细胞异常过度放电和异常放电进一步扩展形成的。
Objective To analyze the causes, pathogenesis and prevention of traumatic epilepsy following traumatic epilepsy in severe craniocerebral injury. Methods The clinical features and treatment results of secondary traumatic epilepsy in the treatment of severe craniocerebral injury were retrospectively analyzed. Results 946 cases of severe head injury in 103 cases of secondary epilepsy, the incidence rate of 10.9%. There were 39 cases (37.9%) with craniocervical comminuted fracture, 28 cases with open craniocerebral injury (27.2%), 25 cases with intracranial hematoma (24.3%) and 11 cases with simple cerebral contusion (10.7%). Conclusions Severe traumatic brain injury secondary to traumatic epilepsy is the structural damage and neuro-suppression of nerve cells, the destruction of negative feedback system and the abnormal over-discharge of nerve cells and abnormal discharge.
