Abstract

Introduction: Venous outflow obstruction is a common condition among patients with chronic venous insufficiency. Endovascular treatment is favourable over open surgery. This study aimed to assess stent patency and clinical outcome in venous outflow obstruction of lower limbs, and also to compare it between post-thrombotic syndrome and non-thrombotic iliac vein lesions. Material and methods: The study was a historical cohort study. Patients with chronic deep venous insufficiency referred to our tertiary referral centre who underwent venoplasty were recruited. Patients were divided into two groups: non-thrombotic-iliac-vein-lesions and post-thrombotic syndrome. Stent patency rate, clinical improvement and risk factors were evaluated during a six-months course after venoplasty. Results: One-hundred-sixty-four patients were included. Six-months primary, assisted primary and secondary patency rates were 98.86%, 100% and100% in the non-thrombotic-iliac-vein-lesions group and 88%, 93% and 96% in the post thrombotic syndrome groups (p-value =.005, p-value =.02, and p-value =.09, respectively). Pain, claudication and edema were the most common symptoms in both groups and significantly improved after six months. Early thrombosis in the PTS group was more common (9 vs. 1, P value =.007). Conclusion: Percutaneous stenting in patients with venous outflow obstruction is safe and effective with a high patency rate and significant decrease in clinical score in both post-thrombotic syndrome and non-thrombotic-iliac-vein lesions groups. © 2019, © 2019 Society of Medical Innovation and Technology.
