Stress-Strain Analysis in Anastomoses of Arteries with Vascular Grafts
Original language description
Failures and other clinical complications concerning surgical connections (anastomoses) between a natural artery and an autograft or artificial vascular graft represent a challenging biomechanical problem. Stress-strain analyses aim at reduction of extreme stresses or strains in the anastomosis and at reduction of stiffness mismatch among the artery, graft and anastomosis. In this way, they can contribute to lowering the risk of postsurgical complications (leakage, ruptures, growth of secondary aneurysmmas etc.). Stress-strain states in various types of end-to-end anastomoses of either two identical parts of aorta (coarctation of aorta) or in connection between aorta and an artificial (knitted) vascular graft were modelled using finite element programsystem ANSYS. Quasistatic analyses using axisymmetric model assumed a nonlinear elastic, homogeneous, isotropic, nearly incompressible material of aortic wall or of each of the two major layers. The constitutive model of knitted vascular
