外伤性颅内迟发性血肿CT诊断的意义

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。

CT Diagnosis Significance in Traumatic Skull Hangfire Haematoma

Objective： To discuss the characteristics and regulation of the delayed traumatic intracranial hematoma in order to provide reliable basis for clinical diagnosis and treatment timely. Methods： The first CT scanning of 136 patients of delayed traumatic intracranial hematoma and the happening time of delayed traumatic intracanial hematoma were analyzed. Results： Most of the first CT scanning of delayed traumatic hematoma patients are unusual, it shows subarachnoid hemorrhage, brain edema, contusion and laceration; the summit of delayed traumatic intracranial hematoma was after 24 to 72 hours of the wound. Conclusion： Most of the first CT scanning of delayed traumatic intracranial hematoma are unusual; the summit time of delayed traumatic intraeranial hematoma is after 24 to 72 hours of the wound.
