Flow pattern and shear stress distribution in distal end-to-side anastomosis

Adamiec J., Matecha J., Netrebska H., Tuma J.

Acta of Bioengineering and Biomechanics

2006

Vol. 8, nr 1

3-12

We present the results of the first part of the project whose objective is to optimize the shape of anastomosis (end-to-side), which is used for the bypass anastomosis, and thus to minimize the negative impact of the flow dynamics on the vascular walls and blood, thanks to which the bypass failure risk can be successfully reduced. The Particle Image Velocimetry (PIV) method is used for experimental measurements that are combined with numerical solution. The goal of this work was to develop, both experimentally and numerically, a basic idea of flow behind the distal end-to-side bypass junction, depending on the connection angle both in steady and unsteady conditions.
