Pharmaco Mechanical Thrombolysis Associated With Anticoagulation Compared With Anticoagulation in the Acute Phase of Very Symptomatic Proximal Venous Thrombosis of the Lower Limbs.

Brief Summary

* Iliofemoral DVTs (IF DVTs) are vascular disorders associated with high morbidity and mortality, which can be complicated by long-term post-thrombotic syndrome (PTS). * Pharmaco mechanical thrombolysis (PMT) is an innovative endovascular technique involving in situ fibrinolysis of the thrombus in the acute phase of thrombosis, followed by mechanical extraction by fragmenting the thrombus. * The American ATTRACT study showed that management by catheter-directed thrombolysis and/or PMT in the acute phase is safe and effective at 2 years in a subgroup of DVTif compared with anticoagulation (18% moderate or severe SPT with thrombolysis vs. 28% without thrombolysis). * PMT-DVT will be the first study to assess the medium (30 months) and long-term (60 months) efficacy of PMT in the French context, using data from the French National Health Data System.
