FACTORS INFLUENCING THE TREATMENT OUTCOMES OF LOWER EXTREMITY DEEP VEIN THROMBOSIS WITH ENDOVASCULAR INTERVENTION
Main Article Content
Abstract
Background: Lower extremity deep vein thrombosis (DVT) is a serious condition that can lead to complications such as pulmonary embolism (PE), and post-thrombotic syndrome (PTS). Endovascular intervention has proven effective in rapidly resolving thrombi and reducing PTS risk, but the factors influencing treatment outcomes are not well understood. Objectives: To identify factors affecting the treatment outcomes of acute lower extremity DVT using endovascular intervention, particularly the development of post-thrombotic syndrome. Materials and methods: A retrospective study was conducted on 35 patients treated with endovascular intervention at Cho Ray Hospital from January 2017 to December 2022. Outcomes were evaluated based on thrombus resolution and venous patency rates one-month post-intervention. The relationship between risk factors and PTS development was analyzed. Results: Thrombus resolution of grades 2 and 3 was achieved in 94.7% of patients, with 100% venous patency after one month. PTS occurred in 37.1% of cases, mostly mild. Advanced age, comorbidities, and obesity were significantly associated with PTS development (p<0.05). Conclusions: Endovascular intervention is an effective and safe treatment for acute lower extremity DVT. The advanced age, BMI and residual iliac vein stenosis were shown to be associated with the development of post-thrombotic syndrome after intervention.
