From the deep venous thrombosis to the post-thrombotic syndrome

Post-thrombotic syndrome or post-thrombotic disease (PTD) is the set of chronic venous symptoms and/or signs secondary to deep vein thrombosis of the lower limbs. It manifests itself in 20% to 60% of cases within two years after the thrombosis. Evolution of the thrombotic vein is described. The diagnosis is clinical with the Vilalta score including 5 subjective criteria and 6 objective criteria with the presence or not of a leg ulcer. The diagnosis of PTD must be evaluated as soon as possible by echo-doppler. This pathology is responsible for an alteration in the quality of life and a burden in public health e linked to leg ulcers, which are present in 5% of cases. Recommendations have been published with the aim of reducing the occurrence of PTD through early treatment of thrombosis and the prescription of medical elastic compression. In severe post-thrombotic syndromes, new recanalization therapies can reduce venous hypertension and recurrence of leg ulcers. Deep vein surgery with valvular repair has the same objectives.
