目的:探讨外伤性硬膜下积液(TSE)患者演变为慢性硬膜下血肿(CSDH)的机制。方法:对我科23例外伤性硬膜下积液演变为慢性硬膜下血肿的患者进行观察分析。结果:23例患者演变为慢性硬膜下血肿的时间为伤后22~96 d,演变为血肿后症状均加重,23例患者经颅骨钻孔引流术均治愈。结论:外伤性硬膜下积液是慢性硬膜下血肿来源之一,其演变机制有多种原因。
Objective: To investigate the mechanism of chronic subdural hematoma (CSDH) in patients with traumatic subdural effusion (TSE). Methods: 23 cases of traumatic subdural effusion in our department evolved into chronic subdural hematoma in patients with observation and analysis. Results: Twenty-three patients developed chronic subdural hematoma from 22 to 96 days after injury. The symptoms were all aggravated after hematoma evolved. Twenty-three patients were cured by cranial drainage. Conclusion: Traumatic subdural effusion is one of the sources of chronic subdural hematoma, and its evolution mechanism has many reasons.
