影响慢性硬膜下血肿钻孔引流术后复发的因素分析

Influencing factors for recurrence after borehole drainage for chronic subdural hematoma

目的探讨影响慢性硬膜下血肿钻孔引流术后复发的相关因素。方法回顾性分析应用钻孔引流术治疗的160例慢性硬膜下血肿患者的临床资料,采用多因素Logistic回归分析影响术后复发的相关因素。结果 160例患者中,术后复发14例（8.75%）,复发时间15天~12月。单因素分析显示年龄（P=0.049）、血肿体积（P=0.004）、术前中线移位（P=0.019）及血肿厚度（P=0.024）与术后复发有关。多因素分析显示血肿体积（P=0.008）是影响患者术后复发的独立因素。结论慢性硬膜下血肿钻孔引流术后复发因素有许多,血肿体积可作为评估复发因素的独立指标。

Objective To investigate the influencing factors for recurrence after borehole drainage（ BHD） for chronic subdural hematoma（ CSDH）. Methods The clinical data of 160 patients with CSDH who underwent BHD were analyzed retrospectively. The multivariate logistic regression analysis was used to determine the influencing factors for postoperative recurrence. Results Of all the 160 patients,14（ 8. 75%） experienced postoperative recurrence,and the time to recurrence ranged from 15 days to 12 months. The univariate analysis showed that age（ P = 0. 049）,hematoma volume（ P = 0. 004）,preoperative midline shift（ P = 0. 019）,and hematoma thickness（ P = 0. 024） were associated with postoperative recurrence. The multivariate analysis showed that hematoma volume（ P =0. 008） was the independent risk factor for postoperative recurrence. Conclusions Several factors influence the recurrence after BHD for CSDH,and hematoma volume can be used as an independent predictor for postoperative recurrence.
