Over the past decade, there have been great innovations in the diagnosis of venous disorder since the introduction of dual-source computed tomography (DSCT) in 2006. It provides fast and reliable diagnosis of deep vein thrombosis (DVT) with the capability of full leveling of thrombus burden and allows early endovascular interventions with pharmacomechanical aspiration thrombectomy (PMAT) being performed aiming to reduce the post-thrombotic syndrome (PTS) and improve quality of life. The newly introduced ultrafast clot removal system, in patients who failed with PMAT, AngioJet, and EKOS, aids in rapid restoration of venous flow and decline of venous hypertension to mitigate the valve damage. Percutaneous transluminal angioplasty (PTA) and stenting yield high technical success rate of 93–96% and a promising short-term 1-year and 2-year patency of around 93% and 75–79%, respectively, for symptomatic May-Thurner syndrome (MTS). Based on the cumulative endovascular treatment experience in over 2000 cases in Xizou, China, some relevant precipitating factors are addressed, and a new classification of subtypes have been proposed to guide the proper selection of endovascular management of Budd-Chiari syndrome (BCS).
