摘要
目的探讨创伤性双侧慢性硬膜下血肿(BCSDH)的CT特征及危险因素。方法回顾有随访资料的创伤性慢性硬膜下血肿(CSDH)52例。先研究其CT表现,然后采用多因素Logistic回归分析从以下变量中,如年龄、性别、伤后"潜伏"时间、受伤着力部位、受伤时有无昏迷经过、伤时CT表现等确定BCSDH发生的影响因素。结果在52例创伤性慢性硬膜下血肿中,BCSDH(23例)占44.2%。BCSDH除具有单侧CSDH的CT特征外,尚具有自身的一些特点。在多因素Logistic回归分析中,与双侧血肿发生显著相关的因素为年龄,当年龄>70岁时,双侧血肿发生的危险度大。结论对于高龄患者,应警惕BCSDH的发生。为此,仔细研究其CT特点是必须的。
Objective To explore some CT characteristics and risk factors for traumatic chronic bilateral sub- dural hematoma （BCSDH）. Methods A total of 52 patients with chronic subdural hematoma （ CSDH） were reviewed. Some CT characteristics of BCSDH were studied first. Then, the risk factors for BCSDH were determined by logistic regression model from the following variates： age, gender,prediagnostic duration, site for injury force, co- ma experience and CT showing after injury. Results BCSDH was observed in 44.2% of 52 patients with CSDH. BCSDH showed its special CT characteristics in additional to those similar with unilateral CSDH. In logistic regres- sion model, age was a significant risk factor for BCSDH. The patients over 70 year old were more likely to have BCSDH. Conclusion BCSDH should be paid more attention in the old age, so careful study on CT characteristics is indispensable.
