| Summary: | Clinical applications of computational modelling is a
fundamentally new approach in medical treatment planning and
development of predictive methods. In case of cardiovascular
disease, these methods could enable physicians to predict the risk
of rupture and to determine the optimal hemodynamic
conditions for an individual patient. Abdominal aortic aneurysm
(AAA) is a common clinical problem. We present a
computational simulation which can be used in the predictive
medicine, especially in the diagnosis and treatment of AAAs. For
this purpose, we developed a code that provides an integrated set
of tools to model clinically relevant hemodynamic conditions
important in predicting risk of rupture of AAAs. The blood flow
dynamics was solved according to the incompressible Navier-
Stokes equations for Newtonian fluids. The pulsatility of blood
flow was considered. The computational application is based on
the three-dimensional finite element method. A typical idealised
fusiform AAA model was used to study the flow effects, flowinduced
wall shear stresses and pressure. These three criterias
play an important role in assessing the hemodynamics in AAAs. (Abstract by authors) |
