Preservation of Venous Valvular Function After PMT for Acute DVT

Effect of Endovascular Thrombectomy for Femoral Popliteal Vein Thrombosis on Venous Valve Function Maintenance: a Single-center, Single-arm Prospective Observational Study

To evaluate the venous valvular function after pharmacomechanical thrombectomy (PMT) for acute femoral-popliteal venous thrombosis.

All patients presenting with symptoms in the lower extremity due to the femoral venous thrombosis involving or not involving iliac and popliteal veins treated with percutaneously pharmacomechanical catheter-directed thrombolysis via AngioJet devices or anticoagulation alone were included in this study.

Inclusion Criteria:

• Patients with acute symptomatic proximal DVT involving the femoral, and/or popliteal vein, common femoral vein, iliac veins (with or without other involved ipsilateral veins) were enrolled at seven vascular centers in China. Patients were treated with PCDT via Zelante device (Boston Scientific).

Exclusion Criteria:

• Participants were excluded if they had symptoms for more than 14 days.
