CT诊断迟发性外伤性颅内血肿28例

28 CASES OF DELAYED TRAUMATIC INTRACRANIAL HEMATOMA DIAGNOSED BY CT

目的 探讨迟发性外伤性颅内血肿 (DTIH)发病特点。方法 分析DTIH发病时间、CT影像并讨论其机制。结果 2 8例DTIH在伤后 2 4～ 48h发病 2 3例 ,占 81 .1 5 % ,脑实质血肿 2 5例 ,占 89.2 9% ,发生机制为损伤血管受病理损害引起迟发性出血。结论 2 4～ 48hCT复查是及早发现DTIH的最佳时期。

objective To research the characteristics of delayed traumatic intracranial hematona(DTIH). Methods Analysed the developed time of DTIH and CT photograph and discussed the mechanism. Results 23 Of the 28 cases with DTIH occured the disease after wounded 24～48 hours(81.15%);25 cases of which were encephalemia (89.29%). The mechanism was that the blood vessel's pathological damages led to delayed hemorrhage. Conclusion To take a CT inspection within 24～28 hours is the best time to discover delayed traumatic intracranial hematoma.
