Should the Proximal Part of a Bifurcated Aortic Graft be Kept as Short as Possible? A Computational Study Elucidates on Aortic Graft Hemodynamics for Various Main Body Lengths
TLDR
In this paper , the authors investigate the hemodynamic effect of different main body lengths in bifurcated aortic grafts using 3D computer models, and they show that a long main body of a Bifemoral surgical graft results in significantly reduced total resistance compared to a short proximal main tube with two long distal limbs, while the differences observed in TAWSS, OSI and RRT between models are small.About:

Classification of Blood Rheological Models through an Idealized Symmetrical Bifurcation
TL;DR: In this paper , the authors group sixteen blood rheological models in homogeneous clusters, by exploiting data generated from numerical simulations on an idealized symmetrical arterial bifurcation.

Effect of sac asymmetry, neck and iliac angle on the hemodynamic behavior of idealized abdominal aortic aneurysm geometries.
TL;DR: In this paper , the authors performed a parametric study to evaluate the effect of aortic neck angulation, angle between the iliac arteries, and sac asymmetry (SA) on the hemodynamic variables of AAAs.

Inside hemodynamics of bifurcated aortic graft.
TL;DR: In this article , Kontopodis et al. discussed hemodynamics of different sizes and features of implanted bifurcated aortic prostheses merits to be deepened in some pathophysiological features.

Selection of Bifurcated Grafts’ Dimensions during Aorto-Iliac Vascular Reconstruction Based on Their Hemodynamic Performance
TL;DR: In this article , the authors evaluate the hemodynamic performance of bifurcated aortic grafts and relate those with proximal/distal part length ratios (the angle φ between the limbs is used as a surrogate marker of the main body-to-limb length ratio).

TL;DR: A novel technique to assess the relation between fluid dynamic variables and the permeability of the endothelium to macromolecules indicates that in vivo endothelial permeability to albumin decreases with increasing time-average shear stress over the normal range.
