Originální abstrakt

A computational model of surgical connection of two identical parts of arteries is presented in the paper as an example of stress-strain analysis of vascular anastomoses realized using finite element method. The axisymmetric model assumes hommogeneous isotropic incompressible non-linear elastic material behaviour. The model is loaded by inner pressure and by axial prestretch in the range of normal physiologic values. In addition, it uses a fictive temperature field method to take residual stresses in the arterial wall into account. The extreme stress values in the connection of both parts are compared with compared to the stress components in the intact aorta. Allthough the model is rather simplified, it enables us to evaluate the risk of clinical complications related to mechanics (aneurysma initiation, leackage, wall rupture) by comparison of the stress increase in the individual types and geometries of anastomoses.
