Guidance of Venous Stent Implantation after Catheter-directed Thrombosis in Patients with Acute Left Lower Extremity Deep Venous Thrombosis based on Pressure Gradient Differences between the Iliac Vein and Inferior Vena Cava: A Single-center Retrospective Study

摘要

Background: Iliac vein compression syndrome (IVCS) can lead to acute deep venous thrombosis (DVT) and post-thrombotic syndrome (PTS). Endovascular venous stenting has become a preferred treatment for IVCS. In this article, we guide stent implantation by the pressure gradient of iliac vein and inferior vena cava. To evaluate the feasibility of guidance of venous stent implantation based on venous pressure gradient difference.
