外伤性硬膜下积液演变的慢性硬膜下血肿

目的 探讨外伤性硬膜下积液演变为慢性硬膜下血肿的几率、机理和临床特点。方法 回顾性分析32例外伤性硬膜下积液演变为慢性硬膜下血肿患者的临床资料及有关文献。结果 本组16.7%的外伤性硬膜下积液病例演变为慢性硬膜下血肿;积液演变为血肿的时间为伤后22－100d;经钻颅血肿引流均治愈。结论 外伤性硬膜下积液是慢性硬膜下血肿的来源之一。发病年龄两极化,常发生在积液量少、保守治疗的慢性型病例中,致病方式常为减速性损伤及合并的颅脑损伤很轻微是外伤性硬莫膜下积液演变为慢性硬膜下血肿患者的临床特点。

Clinical characteristics of chronic subdural hematoma evolving from traumatic subdural effusion

Objective To probe into the incidence, mechanism and clinical characteristics of chronic subdural hematoma (CSDH) evolving from traumatic subdural effusion (TSE). Methods The clinical materials of 32 patients with CSDH evolving from TSH were analyzed retrospectively and the correlative literature was reviewed. Results 16 7% of the patients with TSH evolved into CSDH. The time of evolution was 22 100 days after head injury. All patients were cured with hematoma drainage. Conclusions TSE is one of the origins of CSDH. The clinical characteristics of TSE evolving into CSDH include polarization of patient age, and chronic small effusion. The patients are usually injuried deceleratedly and accompanied with mild cerebral damage.
