Shear-induced platelet activation in the brachial arteriovenous fistula

The video presents the results of computer reconstruction for the process of shear-induced platelet activation in a personalized brachial arteriovenous fistula.

The brachial arteriovenous fistula (AVF) provides constant vascular access in patients on hemodialysis. Native AVF for hemodialysis is a vascular access, created by connecting the veins and arteries of the patient. The video shows the dynamics of hydrodynamic activation of platelets in the AVF. Duration of calculation - 2 heartbeats. Gray color shows the absence of activated platelets, red - a large concentration of activated platelets, blue - a small. The left shows the change of blood flow in time.
