Simulations characterize turbulence caused by common connection for dialysis

The complex interplay among the arteriovenous grafts, the vessels they connect, and the blood they transport has been difficult to simulate, but one new method provides a way. Researchers report simulations that reconstructed the fluid dynamics affected by the insertion of an AVG. They used a model that considered the ability of AVG tubes and blood vessels to deform and found much of the disrupted flow could be mitigated by this flexibility.
