目的:分析探讨脑外伤术后迟发性颅内血肿的发病机理、发病时间及预防措施。方法:总结我院2010.1—2013.12期间52例经CT证实术后迟发性颅内血肿病人,并对其发病时间、影像表现、治疗结果进行分析。结果:脑外伤术后迟发性颅内血肿可发生于硬膜外、硬膜下、及脑内,发现血肿时间为术后48小时以内,67%合并有颅骨骨折,术后6小时以内发现迟发性血肿者疗效明显优于术后6小时以后发现者。结论:脑外伤术后迟发性颅内血肿出血速度快,出血量大,而意识变化较原发血肿轻,应引起高度重视。脑外伤术后常规早期CT检查,早期诊断,早期治疗,可降低死亡率,提高生存质量。 Objective: To analyze the pathogenesis, onset time and preventive measures of delayed intracranial hematoma after traumatic brain injury. Methods: 52 cases of delayed intracranial hematoma confirmed by CT in our hospital from January 2010 to December 2013 were analyzed, and their onset time, imaging findings and treatment results were analyzed. Results: Delayed intracranial hematoma occurred after traumatic brain injury in epidural, subdural and intracerebral hemorrhage. The hematoma time was within 48 hours after operation, 67% had skull fractures, and within 6 hours after operation Delayed hematoma was significantly better than those found after 6 hours. Conclusion: Delayed intracranial hematoma after traumatic brain injury has the advantages of fast bleeding, large amount of bleeding, and less change of consciousness than primary hematoma, which deserves great attention. Conventional early CT examination after traumatic brain injury, early diagnosis, early treatment, can reduce mortality and improve quality of life.
