Description
Shunli Peng and four colleagues published a 2026 study of blood flow forces in dialysis patients. Patients on hemodialysis usually receive treatment through an arteriovenous fistula, a surgically created connection between an artery and a vein in the arm. These fistulas often narrow over time, a problem called stenosis, which threatens treatment.
Wall shear stress, the friction of flowing blood on the vessel wall, drives the remodeling that can cause this narrowing. The team measured shear stress in the brachial artery with ultrasound vector flow imaging. The data covered 113 patients with end-stage renal disease treated between December 2024 and February 2025. Linking shear stress patterns to stenosis could yield an early warning test for failing fistulas.
