Summary:This paper addresses changes in blood flow parameters in the area behind a saccular aneurysm. The hemodynamics modelling was conducted with the ANSYS software using the Lattice Boltzmann method. We performed a computational fluid dynamics simulation of the blood flow in two vessels of 8.4 mm in diameter, one of which contained an aneurysm of 23 mm in diameter, and the other had no abnormalities. The maximum relative deviation of the blood flow velocity registered 35 mm away from the aneurysm, provided the inflow velocity was 86 cm/s at 60 th ms from the start of the simulation, was 38.5% compared to the flow velocity in the normal vessel.
