Summary
Tissue-engineered vascular grafts (TEVGs) show promise for hemodialysis (HD) access when traditional methods fail. This review examines TEVGs in clinical trials, focusing on their characteristics and outcomes for patients needing HD.
Area of Science:
- Biomaterials Science
- Vascular Surgery
- Regenerative Medicine
Background:
- Aging populations and rising chronic kidney disease increase demand for hemodialysis (HD).
- Arteriovenous fistulas (AVFs) are preferred for HD access but have limitations.
- Prosthetic grafts (AVGs) are alternatives but face infection and durability issues, driving TEVG development.
Purpose of the Study:
- To review tissue-engineered vascular grafts (TEVGs) that have reached clinical trials for hemodialysis access.
- To emphasize the characteristics and clinical outcomes of these advanced TEVGs.
Main Methods:
- Literature review of clinical trials involving TEVGs for hemodialysis access.
- Analysis of graft characteristics and reported clinical outcomes.
Main Results:
- TEVGs are being investigated as a solution for patients unsuitable for AVF or experiencing AVG complications.
- Focus on graft properties like biocompatibility, mechanical strength, and integration with host tissue.
- Key clinical outcomes include patency rates, infection rates, and maturation success.
Conclusions:
- TEVGs represent a significant advancement in vascular graft technology for hemodialysis.
- Clinical trial data is crucial for evaluating the efficacy and safety of TEVGs.
- TEVGs hold potential to improve outcomes for patients requiring long-term hemodialysis access.

Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...
