目的:探讨外伤性颅内迟发性血肿CT表现特点和规律,为临床即时诊治提供可靠依据。方法:对136例外伤性颅内迟发性血肿患者首次CT及伤后迟发性血肿发生时间进行分析。结果:外伤性颅内迟发性血肿患者多数首次CT检查,可仅表现为蛛网膜下腔出血、脑肿胀、脑挫裂伤和颅骨骨折;颅内迟发性血肿发生的高峰期为伤后24~72小时。结论:外伤性颅内迟发性血肿首次CT检查多有异常,但无颅内血肿者,应在24~72小时内进行CT复查,以发现颅内迟发性血肿,方不至贻误诊治。
Objective: To explore the features and rules of CT manifestations of traumatic intracranial delayed hematoma and provide a reliable basis for clinical diagnosis and treatment. Methods: The time of first CT and post-traumatic delayed hematoma in 136 patients with traumatic intracranial delayed hematoma were analyzed. Results: Most of the patients with traumatic intracranial delayed hematoma had the first CT examination, which showed only subarachnoid hemorrhage, brain swelling, brain contusion and skull fracture. The peak of delayed intracerebral hematoma occurred after injury 24 ~ 72 hours. Conclusion: The first CT examination of traumatic intracerebral hematoma delayed hematoma, but no intracranial hematoma who should be within 24 to 72 hours for CT review to find intracranial delayed hematoma, not to delay the diagnosis and treatment.
