Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Post-thrombotic syndrome (PTS) is the most common chronic complication of deep vein thrombosis (DVT). The endovascular recanalization and stenting technique has become the gold standard treatment for medically resistant and disabling PTS.

Stent thrombosis is a significant complication of this procedure; the risk factors for thrombosis are poorly understood.

Monitoring the patency of the stent is a key component in maintaining clinical success.

Doppler ultrasound is the first-line diagnostic tool for monitoring patients with venous stents, and has the potential to allow accurate assessment of venous stent obstruction.

Absence of validated morphological and hemodynamic echodoppler criteria for the follow-up of these stents.

• Main objective: Clinical and hemodynamic results of venous recanalisations by stenting in the chronic phase

• Secondary objective (s):

* External validation of hemodynamic criteria proposed in the literature to detect venous stent obstruction
* Risk factors for venous stent restenosis
