Helping dialysis fistulas heal and open better in older adults
BCCMA: Cardiovascular Remodeling following Arteriovenous Fistula Creation: Aging Contributes to Adverse Arteriovenous Fistula Remodeling
This research looks at why dialysis fistulas often don't grow enough in people with kidney failure, especially older adults, and explores ways to help them open and work better.

What this research studies
You'll be part of work led by VA Salt Lake City that studies how veins change after a dialysis fistula is made and why some fail to mature. The team will examine blood and tissue samples and use lab models to study effects of aging, specific collagen proteins, and cellular recycling (autophagy) on vein healing. They will combine patient-derived samples with experimental tests to pinpoint biological changes that block fistula growth. The goal is to identify targets that could lead to treatments or procedures to increase the chance a fistula becomes usable for dialysis.
Who could benefit from this research
Good fit: Ideal candidates are people with end-stage kidney disease who are planning to have or recently had an arteriovenous fistula created for hemodialysis, especially older adults and Veterans.
Not a fit: People without kidney failure, those who already have a well-functioning fistula, or patients not receiving care at participating VA sites are unlikely to benefit directly from this project.
Why it matters
Potential benefit: If successful, this research could lead to treatments or approaches that help more fistulas mature so fewer patients need temporary catheters and complications are reduced.
How similar studies have performed: Past efforts to improve fistula maturation have had mixed results, so this project’s focus on aging, collagen, and autophagy brings newer biological angles that are partly novel.
