Computational fluid dynamics analysis of broad and narrow saccular aneurysms compared to a normal middle cerebral artery model showed results that agreed well with available literature.
Computational fluid dynamics can effectively simulate and compare detailed hemodynamics in normal and aneurysmal cerebral arteries.
Supports CFD hemodynamic modeling in animal aneurysm models; leaves open translation to human risk assessment or practice.
The recent advances in computational fluid dynamics (CFD) can be useful in observing the detailed hemodynamics in cerebral aneurysms for understanding not only their formation and rupture but also for clinical evaluation and treatment. However, important hemodynamic quantities are difficult to measure in vivo. In the present study, an approximate model of normal middle cerebral artery (MCA) along with two cases consisting broad and narrow saccular aneurysms are analyzed. The models are generated in ANSYS WORKBENCH and transient analysis is performed in ANSYS-CFX. The results obtained are compared for three cases and agree well with the available literature.

Khader et al. (2009) studied Cerebral aneurysms. Computational fluid dynamics (CFD) modeling vs. Normal middle cerebral artery model was evaluated on Hemodynamic quantities (transient flow). Computational fluid dynamics analysis of broad and narrow saccular aneurysms compared to a normal middle cerebral artery model showed results that agreed well with available literature.
