[Prosthesis without puncture, 3d generation of vascular access for hemodialysis: a study of Hemasite in 10 patients]

Area of Science:

• Vascular Surgery
• Nephrology
• Biomaterials

Context:

• Hemodialysis requires reliable vascular access.
• Traditional methods like arteriovenous fistulas and grafts have limitations.
• The Hemasite device offers a new approach to vascular access for hemodialysis.

Purpose:

• To evaluate the safety and efficacy of the Hemasite vascular access device.
• To assess the patency rates, complication rates, and patient/staff acceptance of Hemasite.
• To explore the potential benefits of Hemasite in managing complications like venous stenosis.

Summary:

• The Hemasite is a T-shaped, carbon-coated vascular access device with a resealable silicon septum, eliminating the need for skin punctures.
• Implanted with attached PTFE grafts, 10 Hemasite devices were placed in 10 patients, with 63% remaining patent after one year.
• No infectious complications were observed. While thrombosis rates were high, the device allows for local thrombolytic infusion and angioplasty for venous stenosis.

Impact:

• Hemasite shows comparable long-term patency to synthetic grafts, suggesting its viability as an alternative vascular access.
• The absence of infectious complications is a significant advantage.
• The device's unique septum facilitates minimally invasive management of thrombosis and stenosis, potentially improving patient outcomes and reducing procedure-related morbidity.
