Fluid dynamic study in a flexible arteriovenous fistula model

Hemodialysis is the process of extracorporeal dialysis in which the patient's blood is withdrawn through a vascular access (VA) and returned to the patient after passing through a filtration system. Among the most common accesses, the arteriovenous fistula (AVF) is recognized as the best for h...

description	Hemodialysis is the process of extracorporeal dialysis in which the patient's blood is withdrawn through a vascular access (VA) and returned to the patient after passing through a filtration system. Among the most common accesses, the arteriovenous fistula (AVF) is recognized as the best for hemodialysis, providing a continuous and longlasting treatment, however, it has high maturation failure rates. The present work seeks to analyze the pressure field and fluid flow conditions in a flexible arteriovenous fistula with an artery wall thickness greater than that of the vein. Through the reconstruction and treatment of the DICOM files, fabrication of the flexible AVF, adaptation of the experimental workbench and experimental procedures of the AVF, it will be possible to analyze the experimental data. The collected data were analyzed trying to establish a relationship between the pathological regions and the values in the pressure points collected from the system. Finally, it can be concluded that a wall thickness of 1 mm in the venous segment caused a pressure recovery in this segment and a high loss of load located in the region of the anastomosis was observed.
