Temporal evolution of hemodynamics in murine arteriovenous fistula: A micro-CT based CFD study
Fig 7
Cross-sectional average velocity and pressure along the vessel centerline at peak systole for day 7 and day 21 models.
The plots show velocity (red) and pressure (blue) distributions relative to distance from the anastomosis. Both models exhibit characteristic features: a sharp velocity increase preceding the stenosis followed by deceleration, with large velocities occurring 1 mm downstream of the anastomosis. A corresponding abrupt pressure drop is observed immediately before the stenotic region. The pressure drop completes (99%) within 1.5 mm downstream of the anastomosis on day 21, whereas it only occurs 50% over the same distance on day 7.
