外伤性硬膜下积液演变为慢性硬膜下血肿临床特点分析

目的:探讨外伤性硬膜下积液演变为慢性硬膜下血肿的临床特点。方法:回顾性分析5例由外伤性硬膜下积液演变的慢性硬膜下血肿患者的临床表现及演变过程,并复习相关文献。结果:本组59例外伤性硬膜下积液患者有5例演变为慢性硬膜下血肿,转化率8.47%。该5例患者均有明确头部外伤史,血肿位于单侧额颞4例、单侧颞顶1例,血肿形成后临床表现多样。5例患者均接受钻颅血肿引流术治疗,术后痊愈。结论:外伤性硬膜下积液是慢性硬膜下血肿的来源之一,发病年龄有较宽的范围,常发生于颅脑损伤很轻微、积液部位在单侧额颞部、经保守治疗病例中。

Clinic characters of chronic subdural hematoma developing from traumatic subdural effusion

Objective：To probe into the incidence and clinical characteristics of chronic subdural hematoma（CSDH）developing from traumatic subdural hygroma（TSH）.Methods：The clinical date of 5 cases with CSDH developing from TSH were analyzed retrospectively and the correlative literature was reviewed.Results：A total of 5 TSH cases developed into CSDH,with the incidence as 8.47%.All of these 5 cases had clear history of head injury.The locations of the hematoma were frontotemporal（4 cases）and parietotemporal（1 case）,with various clinical characteristics.All patients were cured after treated by burr hole irrigation and continuous closed-system drainage.Conclusions：TSH is a important cause for CSDH.It occurs at extensive ages.The clinical characteristics of TSH developing into CSDH include the mild cerebral damage,the frontotemporal effusion,susceptible patients undergoing conservative treatment.
