ABSTRACT

Objective To evaluate the predicting risk factors for fatal pulmonary embolism (PE) in patients with acute deep venous thrombosis of the lower limbs.Methods 182 consecutive patients with acute deep vein thrombosis in the lower limbs were retrieved from our hospital between January 2011 and May 2015.Collected clinical data for all patients included,demographic,body mass index,Wells score.The possible risk factors in patients with PE were retrospectively analyzed.Results The total incidence rate of symptomatic PE in 182 patients was 14.28％.Through muhivariate logistic regression analysis,we found that Wells score,location of thrombosis,inpatient days,bone fracture was significantly associated with symptomatic PE (P ＜ 0.05).Conclusion Higher Wells score,Proximal thrombosis and fracture are the high risk factors related with symptomatic PE.
