目的:分析迟发性外伤性颅内血肿的危险因素。方法:将133例脑外伤患者分为两组,按GCS评分、影像学表现、凝血指标等因素进行回顾性分析。结果:32例发生迟发性颅内血肿的患者年龄大,GCS评分低,发生时间多在伤后24 h内,院前经甘露醇治疗及CT表现为挫裂伤、颅骨骨折的患者易发生迟发性颅内血肿。外伤凝血障碍患者是引起迟发性颅内血肿的重要因素。结论:颅脑外伤后迟发性颅内血肿的发生与诸多危险因素相关,动态复查CT能早期发现。
Objective: To analyze the risk factors of delayed traumatic intracranial hematoma. Methods: 133 cases of traumatic brain injury were divided into two groups according to GCS score, imaging findings, coagulation parameters and other factors were retrospectively analyzed. Results: Thirty-two patients with delayed intracranial hematoma were older, had lower GCS score, and occurred more time within 24 h after injury. Mannitol in hospital and CT showed contusion and laceration, and patients with skull fracture were prone to occur Delayed intracranial hematoma. Patients with traumatic coagulopathy are important factors that cause delayed intracranial hematoma. Conclusion: The incidence of delayed intracranial hematoma after craniocerebral trauma is related to many risk factors. Dynamic CT can be detected early.
