Abstract
BACKGROUND Computational fluid dynamics provides a new method for the study of the blood flow characteristics of the formation and development of intracranial aneurysms. OBJECTIVE To compare blood flow characteristics between the healthy internal carotid artery and normal intracranial aneurysms. METHODS The internal carotid arteries were simulated to obtain hemodynamic parameters in one patient. RESULTS The internal carotid artery associated with aneurysm presents low wall shear stress, high oscillatory shear index, and high particle retention time compared with the normal internal carotid artery. CONCLUSIONS There are differences in blood flow between the normal internal carotid artery and intracranial aneurysm. The vortex of the aneurysm will produce turbulence, indicating that it is unstable, which results in the growth and rupture of the aneurysm.
