Analysis of factors that impacts prognostic of interventional therapy for DVT

Abstract

Objective This paper is to analyze the outcome and risk factors of interventional therapy for lower extremity deep venous thrombosis. Methods From July 2012 to June 2015, 65 patients (27 men and 38 women) underwent interventional therapy for deep venous thrombosis of lower extremity. 16 patients underwent conservative therapy, 23 patients underwent catheter-directed thrombolysis, 26 patients underwent mechanical thrombolysis plus catheter-directed thrombolysis. Results Follow up duration are 1 to 30 months. During the follow up duration, 13 patients replase or fail treated, the cured rate was 80.0%. The average hospitalization time is 16.2 d.The result of single factor study and logistic regression analysis show that the treatment methods and the stages of thrombosis are the prognosis factors. Multivariate multiple linear regression analysis show that the stages and location of thrombosis, and the filter influence the duration of hospitalization. Conclusions The treatment methods and the stages of thrombosis influence the prognosis of DVT with thrombolysis therapy. The stages ,locations of thrombosis and the filter will influence the duration of hospitalization.
