Abstract

Objectives: To investigate the incidence of post-thrombotic syndrome in the patients after sugical treatment of lower extrimity deep venous thrombosis. Methods: Descriptive cross-sectional study in patients who had lower extremity deep vein thrombosis at iliac-femoral segment undergoing surgical treatment (open thrombectomy and endovascular intervention) after in the Thoracic and Vascular department, UMC, Ho Chi Minh City from January 2016 to December 2020. Results: 65 patients were treated with surgical thrombectomy; 50 patients were treated with endovascular intervention. The mean age was 47.3 ± 15.0 years old. It was accounted for 39.1% patients in the age from 40 to 60 years old. Most of the patients had complete thrombosis on contrast-enhanced computed tomography scan (98.3%). May-Thurner syndrome accounted for 68.7%. Of 28.9% patients  was confirmed with post-thrombotic syndrome after treatment. This rate in the open thrombectomy group was 30.2% and the endovascular intervention group was 26.5%. There was no statistically significant difference in the rate of post-thrombotic syndrome in the 2 groups (p=0.72). There was a statistically significant association between time to onset and post-thrombotic syndrome: patients with symptom onset > 7 days had an increased rate of post-thrombotic syndrome compared with the group < 7 days with p = 0.004. There is a statistically significant association between obstructive lesions and post-thrombotic syndrome. (p<0.001). Conclusion: Post-thrombotic syndrome had been need follow-up after treatment of acute lower extremity deep vein thrombosis.
