Background: The purpose of this study was to propose an emerging endovascular technique and describe results of endovascular intervention in treating chronic Iliofemoral Deep Vein Thrombosis (DVT).Methods: From January 2009 to October 2014, 37 patients with chronic obstructive iliofemoral DVTs received successful endovascular interventions. Thirty four patients with chronic iliofemoral DVT who received successful endovascular angioplasty plus stenting were included in this study. Perioperative and 36-month investigations included clinical severity score, Villalta score, levels of valvular incompetence, and the procedure outcome. The mean duration of the follow-up was 36.5 months.Results: The overall success rate of endovascular technique was 91.9% (34 of 37 patients). Six-month, one-year, 2-year, 3-year primary patency and six-month and one-year assisted primary patency rates were 85.2%(29), 79.4%(27), 70.6%(24), 61.8%(21) and 82.4%(28), 73.5%(25), 64.7%(22) and 58.8%(20), respectively. All patients with technical success had clinical improvement in clinical severity score (CEPA) and Villalta score. However, there’re no significant changes of levels of valvular incompetence. Three patients with active venous ulcers healed approximately three months after the procedure. No mortality, but minimal complications like ecchymosis and hematoma at puncture sites were found.Conclusion: In the present study, endovascular intervention with balloon dilation plus stenting should be considered the treatment of choice for chronic obstructive iliofemoral DVT because of a high technical success rate and a minimal complication.
