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 determine the predictors of risk stratification in non-high risk pulmonary embolism(PE) patients caused by lower extremity deep venous thrombosis(DVT). Methods: Clinical data of total 85 non-high risk PE patients caused by DVT were retrospectively analyzed. CT obstruction index(CTOI) and right-to-left ventricular diameter ratio(RV/LV) were calculated with pulmonary arterial CT angiography(CTA) images. Logistic regression models were used to identify predictors of PE risk stratification. Results: The mean CTOI was 22.9%±15.7%, and the mean RV/LV was 1.0±0.2. Forty-four(51.8%) patients had low risk PE and 41(48.2%) patients had median risk PE. Logistic regression analysis showed that PE symptoms and CTOI were predictors of PE risk stratification(OR: 0.149; P=0.436; P=0.012, 0.000; 95% CI: 1.673～59.913, 1.101～1.274), and 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), type of DVT(OR 0.576, P=0.468, 95% CI: 0.130～2.555) or laterality of DVT(OR 0.499, P=0.199, 95% CI: 0.173～1.440) were not predictors. Conclusion: In non-high risk PE patients caused by DVT, PE symptoms and higher CTOI value are major predictors of higher PE risk stratification.
