Area of Science:

  • Biomedical Engineering
  • Fluid Dynamics
  • Medical Device Design

Background:

  • Cerebral aneurysms pose significant risks, often treated with stent implantation.
  • Stent characteristics can influence intra-aneurysmal hemodynamics.
  • Understanding flow dynamics is crucial for optimizing stent-based treatments.

Purpose of the Study:

  • To visualize and analyze the impact of stent parameters on blood flow patterns within a cerebral aneurysm model.
  • To investigate how stent strut orientation affects intra-aneurysmal flow velocities.

Main Methods:

  • Utilized a 3-D computer model of a cerebral aneurysm with specific dimensions.
  • Employed Finite Element Method (FEM) based simulations solving the Navier-Stokes equations.
  • Simulated steady flow conditions with defined viscosity and density.
  • Introduced two parallel stent struts, varying their orientation (parallel/perpendicular to vessel axis) and separation.

Main Results:

  • Stent strut placement at the aneurysm neck reduced mean flow speed within the aneurysm.
  • The degree of flow reduction was dependent on the orientation of the stent struts.
  • Flow patterns showed distinct inflow and outflow zones at the aneurysm neck.
  • Strut orientation (parallel vs. perpendicular to the vessel axis) differentially affected mean neck speed.

Conclusions:

  • Stent implantation for cerebral aneurysms can modify intra-aneurysmal flow dynamics by reducing vortical velocities.
  • Stent strut orientation is a critical factor influencing the effectiveness of flow redirection.
  • Simulation results provide valuable data for designing improved stent configurations for aneurysm treatment.
