The Antheor caval filter demonstrated high effectiveness in preventing recurrent pulmonary embolism (1%) and maintaining vena cava patency (98%) in a 2.5-year follow-up. This study assessed filter complications and performance in 300 patients.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Biomaterials Science

Background:

  • Inferior Vena Cava (IVC) filters are crucial for preventing pulmonary embolism in patients with contraindications to anticoagulation.
  • The Antheor caval filter is designed with specific biomechanical features to ensure effective filtration and prevent migration.

Purpose of the Study:

  • To evaluate the long-term effectiveness and safety of the Antheor caval filter in a multicenter setting.
  • To assess potential complications associated with the filter's design and implantation.

Main Methods:

  • A multicenter follow-up study of 300 patients implanted with Antheor caval filters over 6 months to 2.5 years.
  • Inclusion criteria: pulmonary embolism, floating thrombus, or anticoagulation contraindications.

  • Surveillance protocol included clinical evaluation, imaging (radiography, duplex scan, phlebography, scanography), and treatment analysis.

    • Main Results:

    • High effectiveness in preventing recurrent embolism (1% rate).
    • Excellent vena cava patency maintained in 98% of cases.
    • Analysis of filter specifications: filtration principle, alloy, biocompatibility, fixation, and antimigration systems.

    Conclusions:

    • The Antheor caval filter is a safe and effective option for IVC interruption, offering a low rate of recurrent embolism and high vena cava patency.
    • The filter's design features contribute to its successful clinical performance and minimal complications.
