摘　　要：目的探讨下肢深静脉血栓（DVT）引起症状性非高危肺栓塞（PE）的相关危险因素。方法回顾性分析85例DVT引起非高危PE患者的资料,以是否出现症状作为因变量,以CT阻塞指数（CTOI）、右左心室直径比值（RV/LV）、PE危险分层、DVT类型、患病肢体、年龄及性别为自变量引入二元模型进行Logistic回归分析,探求引起非高危PE症状的危险因素。结果Logistic回归分析显示患病肢体、性别、PE危险分层是导致PE出现症状的影响因素,（P值=0.040、0.017、0.011;95%的可信区间：1.236-8.178、0.076-0.777、1.626-39.898）。结论对于非高危PE而言,右下肢DVT、女性及PE严重程度是PE出现症状的危险因素,CTOI及右左心室直径比值与PE是否出现症状无关。Objective To determine the associated factors to symptomatic non-high risk pulmonary embolism in patients with lower extremity deep venous thrombosis. Methods Clinical data in a total of 85 non-high risk PE patients caused by DVT were retrospectively analyzed. Taking occurrence of symptom or not as a dependent, and the computerized tomographic obstruction index （CTOI） ,right-to-left ventricular diameter ratio （RV/LV）, risk stratification of PE, the type of DVT, laterality of leg, age and sex as independents, multivariate binary logistic regression analysis was used to estimate the risk factors of occurrence of symptom in non-high risk PE patients. Results Logistic regression analysis showed that laterality of leg, sex and risk stratification of PE were influential factors of occurrence of symptom in non-high risk PE patients （ P =0.040, 0. 017, 0.011 ; 95% CI： 1.236 -8. 178, 0.076 -0.777, 1.626 -39. 898）. Conclusion For non-high risk PE,the right leg DVT, female and severity of PE are risk factors to symptomatic PE. CTOI and RV/LV are not correlated with symptomatic PE.
