“Early thrombus removal” in iliac-femoral deep vein thrombosis for prevention of post-thrombotic syndrome

The post-thrombotic syndrome (PTS) is a long-term complication of deep vein thrombosis (DVT) of the lower limbs occurring in 40–50% of patients (1). Impaired thrombus resolution with persistent obstruction is involved in the pathogenesis of PTS, similarly to chronic thromboembolic pulmonary hypertension (CTEPH), which however develops only in a small minority of subjects after pulmonary embolism (PE) (2).
