Bedside inferior vena cava (IVC) filter insertion using duplex imaging is safe and feasible for critically ill patients. This approach reduces costs and avoids transport and radiation exposure, proving effective in 85% of cases.

Area of Science:

  • Medical procedures
  • Critical care medicine
  • Vascular interventions

Background:

  • Inferior vena cava (IVC) filters are crucial for preventing pulmonary embolism in high-risk patients.
  • Traditional filter placement often requires transport to specialized imaging suites.
  • Critically ill and multi-trauma patients present unique challenges for invasive procedures.

Purpose of the Study:

  • To assess the safety and feasibility of bedside IVC filter insertion using duplex imaging.
  • To evaluate the efficacy of duplex-directed caval filter (DDCF) placement in intensive care unit (ICU) patients.
  • To determine the success rate of bedside IVC filter procedures in a multi-trauma population.

Main Methods:

  • Prospective evaluation of 53 multi-trauma/critically ill patients requiring IVC filters.

  • Bedside IVC filter insertion using Vena Tech filters under duplex ultrasonography guidance.
  • Screening IVC duplex scans performed to ensure satisfactory visualization prior to attempted DDCF insertion.

    • Main Results:

    • Successful duplex visualization of the IVC was achieved in 85% (45/53) of patients.
    • DDCF insertion was attempted in 87% (46/53) of patients with satisfactory visualization.
    • Bedside insertion was demonstrated to be safe, rapid, and effective in this patient cohort.

    Conclusions:

    • Bedside IVC filter insertion guided by duplex imaging is a safe and feasible option for critically ill patients.
    • This technique significantly reduces procedural costs and avoids patient transport, radiation, and contrast media.
    • Duplex ultrasonography is a reliable tool for guiding IVC filter placement at the bedside when visualization is adequate.
