A head-to-head comparison of two different types of percutaneous mechanical thrombectomy (PMT) - ClotTriever System versus aspiration thrombectomy (including rheolytic thrombectomy) - in patients with acute iliofemoral deep vein thrombosis (DVT) was conducted to determine whether ClotTriever System can improve thrombus clearance rate, reduce the incidence of post-thrombotic syndrome (PTS), and enhance the long-term efficacy of endovascular treatment for acute iliofemoral DVT.
Aged between 18 and 85 years;
Diagnosed with acute iliofemoral venous thrombosis, with thrombosis involving at least the iliac vein and common femoral vein;
Time from symptom onset to endovascular treatment ≤ 14 days;
Patients undergo endovascular treatment with percutaneous mechanical thrombectomy;
Presence of PTS in the limb to be treated in this procedure, or a history of symptomatic DVT in the same limb within the past 2 years;
Concurrent symptomatic acute DVT involving the iliac vein and/or common femoral vein in the contralateral limb;
Known allergy to heparin, low molecular weight heparin, contrast agents, etc.
Concomitant severe pulmonary embolism with hemodynamic changes, such as hypoxia, hypotension, etc.
