慢性硬膜下血肿术后复发的多因素分析

目的 探讨慢性硬膜下血肿(chronic subdural hematoma,CSDH)术后复发的相关因素.方法 回顾性分析171例CSDH患者的临床资料.结果 本组CSDH患者术后共有18例复发,复发率为10.5%.单因素χ＜'2＞检验显示CSDH术后复发与年龄、血肿密度、血肿位置、中线移位、Bender分级、脑萎缩分级、引流量和出血倾向相关(P＜0.05).与性别、麻醉方式和有无外伤史无关(P＞0.05).Logistic多因素分析显示年龄,血肿密度、中线移位、Bender分级、脑萎缩分级和出血倾向为CSDH患者术后复发危险因素(P＜0.05).结论 CSDH患者的年龄、血肿密度、中线移位、Bender分级和出血倾向与患者的预后密切相关,应针对复发的高危因素,做好相应的防治工作.

Multivariate analysis of risk factors related to recurrent chronic subdural hematoma

Objective To explore the risk factors related to recurrent chronic subdural hematoma （CSDH）. Methods 171 cases with CSDH were retrospectively analyzed. Results 18 cases were recurrent after surgery with a recurrent rate of 10. 5%. Single factor χ2 analysis showed that the recurrence of CSDH was related to age, hematoma density, hematoma location, midline shift, Bender classfication, eneephalatrophy classfieation,drainage amount,and bleeding tendency （P 〈 0.05）, regardless of gender, anesthesia mode,and injury history （P 〉 0.05）. Age,hematoma density,midline shift,Bender elassfication,encephalatrophy classfication,and bleeding tendency were found to be independently associated with the recurrence of CSDH by Logistic multifactorial analysis （P 〈 0.0.5）. Conclusions Patient age, hema- toms density,midline shift,Bender classfieation,encephalatrophy classfication,and bleeding tendency are prognostic factors fpatients for with CSDH. We should pay more attention to the recurrent risk factors, and implement corresponding prevention strategies.
