[Long term experience with the LifeSite hemodialysis device]

Area of Science:

• Nephrology
• Vascular Access

Context:

• Arteriovenous fistula creation is not possible for all hemodialysis patients.
• Central venous catheters are often used, but long-term efficacy and complication rates vary.
• The LifeSite hemodialysis access system offers an alternative approach.

Purpose:

• To report on the long-term use and efficacy of the LifeSite hemodialysis access system.
• To evaluate blood flow rates, infection rates, and overall device performance.
• To assess the LifeSite system as an alternative for patients without fistula creation options.

Summary:

• The LifeSite system, a central venous catheter with a titanium alloy valve, was used in six patients for long-term hemodialysis.
• Excellent blood flow (300-345 ml/min) was achieved with two devices, and single-needle dialysis was possible with one.
• The infection rate was low (1.7 episodes/1,000 days), with most devices remaining functional for over three years.

Impact:

• The LifeSite system provides an effective and durable alternative for hemodialysis vascular access when arteriovenous fistulas cannot be created.
• Successful long-term dialysis can be maintained, improving patient management and quality of life.
• The system demonstrates a favorable safety profile with manageable complications.
