【摘要】：目的:探讨下肢深静脉血栓(DVT)引起非高危肺栓塞(PE)危险分层的预测因素。方法 :回顾性分析85例DVT引起非高危PE患者的临床资料,通过CTA图像计算CT阻塞指数(CTOI)值及右左心室直径比值(RV/LV),以Logitic回归分析来探求影响非高危PE危险分层的预测因素。结果:平均CTOI为(22.9±15.7)%,RV/LV为1.0±0.2;低危PE者44例(51.8%),中危PE者41例(占48.2%);Logitic回归分析显示是PE症状及CTOI是非高危PE的预测因素(OR:10.012、1.184;P=0.012、0.000;95%CI:1.673~59.913、1.101~1.274),而RV/LV(OR:0.149;P=0.436;95%CI:0.001~17.913)、年龄(OR:1.028;P=0.344;95%CI:0.971~1.089)、性别(OR:2.976;P=0.231;95%CI:0.500~17.727)、下肢DVT类型(OR:0.576;P=0.468;95%CI:0.130~2.555)、患病肢体(OR:0.499;P=0.199;95%CI:0.173~1.440)不是其危险因素。结论:对于DVT引起的非高危PE来讲,PE出现症状及CTOI值升高是PE危险分层高的主要预测因素。
[Abstract]:Objective: to investigate the prognostic factors of risk stratification of non-high-risk pulmonary embolism (PE) caused by deep venous thrombosis (DVT) of lower extremity. Methods: the clinical data of 85 patients with non-high risk PE caused by DVT were retrospectively analyzed. The (CTOI) value of CT occlusion index and the right left ventricular diameter ratio (RV/LV) were calculated by CTA images. Logitic regression analysis was used to explore the prognostic factors of non-high-risk PE risk stratification. Results: the average CTOI was (22.9 卤15.7)%, RV/LV was 1.0 卤0.2, low risk PE was 44 cases (51.8%), moderate risk PE was 41 cases (48.2%). Logitic regression analysis showed that PE symptoms and CTOI were predictors of non-high-risk PE (OR:10.012,1.184;P=0.012,0.000;95%CI:1.673~59.913,1.101~1.274), while RV/LV (OR:0.149;P=0.436;) 95%CI:0.001~17.913, age (OR:1.028;P=0.344;95%CI:0.971~1.089), sex (OR:2.976;P=0.231;95%CI:0.500~17.727), lower extremity DVT type (OR:0.576;P=0.468;) 95%CI:0.130~2.555), OR:0.499;P=0.199;95%CI:0.173~1.440 is not a risk factor. Conclusion: for non-high risk PE caused by DVT, the symptoms of PE and the increase of CTOI are the main predictors of high risk stratification of PE.
