Abstract

The purpose of this work is to evaluate the influence of coil diameters on the hemodynamics of intracranial aneurysms by using computational fluid dynamic (CFD) simulations. Three virtual treatments were performed varying packing density and coil surface area, by changing coil diameter. Hemodynamic parameters such as wall shear stress (WSS), average velocity and dye concentration at the aneurysm site were qualitative and quantitatively analyzed. Simulations with same coil area (958 mm 2) but different packing density (21.0% and 41.6%) show similar hemodynamic alterations. Besides, the treated model with the highest coil area (1596 mm 2) and intermediate packing density (33.2%) exhibited the highest reduction in the studied hemodynamic variables. Our findings show that coil area plays an important role in the resistance (pressure and frictional drags) of blood flow through the coils.
