A novel subcutaneous vascular access device, Dialock, shows promise for hemodialysis (HD) patients. It offers successful long-term function and high blood flow rates, potentially improving upon existing HD access methods.

Area of Science:

  • Nephrology
  • Vascular Surgery
  • Biomedical Engineering

Background:

  • Vascular access is crucial for hemodialysis (HD).
  • Current devices face challenges with patency and infection.
  • A new subcutaneous device aims to improve HD vascular access.

Purpose of the Study:

  • To evaluate the safety and efficacy of the Dialock subcutaneous device for hemodialysis vascular access.
  • To assess device function, blood flow rates, and complication rates.

Main Methods:

  • Implantation of the Dialock subcutaneous device in 10 outpatients.
  • Device accessed percutaneously for hemodialysis.
  • Interdialytic patency maintained with heparin lock.
  • Functionality assessed over 6 months, tracking blood flow, pressures, and complications.

Main Results:

  • Successful function for over 6 months (>400 dialysis sessions) in all 10 patients.
  • Consistent achievement of high blood flow rates (>300 ml/min).
  • Satisfactory condition of puncture sites; four systemic infections resolved without device removal.

Conclusions:

  • The Dialock subcutaneous device provides effective and durable vascular access for hemodialysis.
  • It demonstrates high blood flow capacity and acceptable complication rates.
  • The device represents a potential improvement over conventional hemodialysis access methods.
