| dc.description.resumo | Hemodialysis is considered the best treatment for patients with chronic kidney failure. For this treatment, the creation of a vascular access is necessary. One common complication in the arteriovenous fistula (AVF) is the steal syndrome (SD), characterized by reduced distal blood flow that is redirected to the low-resistance venous fistula. This study analyzed the pressure field in an AVF model (in vitro) under SS conditions. The ideal AVF was manufactured using 3D printing, with five pressure acquisition points and an anastomosis angle (AA) of 45º. For the experimental analysis, MPX5050DP pressure transducers, ⅓″ ball valves, USN-HS41TA flow sensors, an S-60-12 pump, and an Arduino UNO microcontroller were used. The AVF was subjected to two configurations: Configuration A, with a maximum average flow rate of 2163.26 ml/min in the proximal artery and zero flow in the distal artery, and Configuration B, with 70% of the maximum average flow rate in the proximal artery and 30% in the distal artery. In the experiments, for Configuration A, the pressure differential ranged from 14.20 kPa at Pressure Point 1 (P1) to 1.00 kPa at Pressure Point 5 (P5). For Configuration B, the pressure ranged from 11.65 kPa at P1 to 1.20 kPa at P5. It can be inferred that the AA is responsible for most of the energy dissipation in the flow. | pt_BR |
