Abstract
Within the field of research that proposes models for arteriovenous fistula (AVF), more detailed studies are needed due to the wide use of AVF in the treatment of patients with chronic renal failure (CRF). This mechanism can easily become damaged due to the numerous accesses necessary for treatment, and may accrue various problems such as infection, thrombosis, stenosis, hand edema, pseudoaneurysm among others. When the AVF loses its function, a new one must be designed to continue the treatment, which further weakens the patient. The present design uses images generated by computed tomography (CT) scans of a patient with a fistula for the design of a solid model from a rapid prototyping process (3D printing), and then to build a mold for the construction of arteriovenous fistula model, with silicone based material. The models were subjected to mechanical tests in order to analyze the behavior of the AVF applying different loads, and thus obtained an equivalent thickness of silicon to the actual parameters of a blood vessel. Research findings point to a future application in real flow, corroborating the results of associated studies in bioengineering that also aim to promote improvement in the quality of life of patients with chronic renal failure.
