Purpose of the Study:

  • To demonstrate the efficacy of computer simulations in predicting cerebral aneurysm behavior.
  • To highlight the potential of computational fluid dynamics (CFD) as a diagnostic tool.
  • To assess the role of CFD in improving surgical treatment planning for aneurysms.

Main Methods:

  • Utilizing computational fluid dynamics (CFD) to simulate blood flow within cerebral aneurysms.
  • Analyzing hemodynamic parameters, including shear stress levels, throughout the cardiac cycle.
