This study shows that polyurethane catheters with a subcutaneous tunnel over 6 cm are safe and effective for prolonged venous access in chronic disease patients. These devices had no insertion complications and lasted an average of 95 days.

Area of Science:

  • Medical Devices
  • Vascular Access
  • Chronic Disease Management

Background:

  • Prolonged venous access devices (PVAD) are essential for managing chronic diseases.
  • Effective PVADs improve patient quality of life and treatment adherence.
  • Optimizing PVAD selection and placement is crucial for patient outcomes.

Purpose of the Study:

  • To evaluate the safety and efficacy of polyurethane catheters with a subcutaneous tunnel > 6 cm for PVAD.
  • To assess the complication rates associated with the insertion of these specific PVADs.
  • To determine the average indwelling time and functional lifespan of these PVADs.

Main Methods:

  • Retrospective analysis of 50 PVAD placements over 3 years.
  • Utilized polyurethane catheters with a subcutaneous tunnel exceeding 6 cm.

  • Monitored for complications during insertion and throughout the device's indwelling period.

    • Main Results:

    • Fifty PVADs were successfully placed without any insertion-related complications.
    • The average duration these PVADs remained functional was 95 days.
    • The indwelling time ranged significantly, from a minimum of 7 days to a maximum of 425 days.

    Conclusions:

    • Polyurethane catheters with a > 6 cm subcutaneous tunnel are a safe and effective option for prolonged venous access.
    • The insertion procedure for these PVADs is associated with a low risk of complications.
    • These devices demonstrate a considerable functional lifespan, supporting long-term therapeutic needs.
