In a 45-year-old man, after a traffic accident with multiple trauma complicated with extensive thrombosis involving the inferior vena cava and iliac veins, rapid development of severe post-thrombotic syndrome with leg ulcers prevented final orthopaedic reconstructions and recovery. Three years after the accident endovascular reconstruction with venoplasty and stenting of the inferior vena cava and iliac veins was performed. He was successfully treated with the confluence technique, in which dedicated nitinol venous stents were used. After the procedure, collateral circulation disappeared and the ulcers healed. This allowed the end of orthopaedic treatment and rehabilitation. The patient recovered and did not require additional vascular interventions for 6 years after the procedure.
