The authors conducted a study to evaluate the long-term impact of iliofemoral thrombosis on quality of life, venous hemodynamic status and clinical severity, walking capacity, and CEAP class. Patients who had been assessed for iliofemoral deep vein thrombosis since 1990 were called for follow-up. Patients were excluded if they had walking impairment due to arterial disease or unrelated causes. Reflux (superficial and deep) was present in 81% of limbs and 43.6% of patients developed venous claudication. Patients had impaired physical and social functioning, and impaired general and mental health.
