Summary
Hemasite, a novel vascular access device, offers needle-free hemodialysis for patients with difficult vascular access. While generally well-accepted, device cost and potential thrombosis are key considerations.
Area of Science:
- Nephrology
- Vascular Surgery
- Medical Device Technology
Background:
- Chronic hemodialysis patients often have unsuitable peripheral vessels for traditional arteriovenous fistulae.
- Alternative vascular access methods are crucial for long-term treatment, especially when standard options fail.
Purpose of the Study:
- To evaluate the safety and efficacy of the Hemasite vascular access device in uraemic patients undergoing chronic haemodialysis.
- To assess patient acceptance and identify potential complications associated with the Hemasite device.
Main Methods:
- A cohort of thirteen uraemic patients with challenging vascular anatomy received the Hemasite device for vascular access.
- Device usage, patient acceptance, thrombotic events, and infectious complications were prospectively monitored.
Main Results:
- Eight Hemasite devices remained in routine use with high patient acceptance.
- Nine thrombotic events occurred in five patients; thrombectomy was successful in three.
- Two infections led to the loss of one device; three patients died from unrelated causes.
Conclusions:
- The Hemasite device facilitates needle-free haemodialysis, potentially extending the lifespan of vascular access.
- The primary drawback of Hemasite is its associated cost, despite its clinical benefits.
