ABSTRACT

Introduction: The elastic arteries are characterized by a hyper-elastic, anisotropic, non-linear and quasi-incomprehensible behaviour, which depends on the contribution and distribution of the main constituents. Its evaluation through constitutive models together with appropriate numerical approaches can potentially contribute to the study of pathologies such as atherosclerosis, as well as to the modelling of surgical interventions or traumas by accident.
Objective: To assess the constitutive models that characterize the biomechanical behavior of the arterial wall for the identification of the adequate potential that allows the correlation of biochemical and mechanical parameters in damage conditions.
Methods: A bibliographic review was conducted from 2010 to 2016 in databases such as: Medline, Cochrane Library, Lilacs, as well as in the metasearch engine Google. There were consulted cohort, prospective, retrospective, clinical, epidemiological studies, bibliographic reviews and clinical trials.
Results: The constitutive anisotropic model of two families of fibers is appropriate to obtain new constitutive relations, which provide of more information about the mechanical properties of the arteries under the influence of the metabolic decontrol generated by the action of diabetes mellitus, in the early stages of atherosclerosis.
Conclusions: The changes in the structure, composition and mechanical properties of the arterial wall as a consequence of the metabolic decontrol allows to assert that the formulation of a suitable model to represent this reality is a crucial stage in obtaining new constitutive relations that contribute to a satisfactory solution in the non-invasive clinical diagnosis of vascular diseases.
