Comparison Of Different Mechanical Thrombectomy Devices in Endovascular Treatment of Acute Iliofemoral Venous Thrombosis
Recruiting now
Conditions studied: Deep Vein Thrombosis
In brief
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.
