目的探讨颅脑损伤术后非手术区迟发性血肿的形成原因、发生机制及临床诊治。方法回顾性分析91例颅脑损伤患者术后出现非手术区迟发性颅内血肿的临床资料。结果根据患者伤后6个月时GOS评分:良好26例,轻残28例,重残16例,植物生存8例,死亡13例。结论颅脑损伤术后发生非手术区迟发性血肿的预后取决于早期预防、早期发现及早治疗,颅内压监测有助于迟发性颅内血肿的诊治,能够改善预后。 Objective To investigate the causes, mechanism and clinical diagnosis and treatment of late hematoma in non-operative area after craniocerebral injury. Methods The clinical data of 91 patients with craniocerebral injury who had delayed intracranial hematoma after operation were retrospectively analyzed. Results According to the GOS score of 6 months after injury, 26 were good, 28 with mild disability, 16 with severe disability, 8 with plant survival and 13 with death. Conclusion The prognosis of delayed hematoma in nonoperative area after craniocerebral injury depends on early prevention, early detection and early treatment. Monitoring intracranial pressure may be helpful for the diagnosis and treatment of delayed intracranial hematoma and prognosis.
