MODELING IN A 3D PACKAGE AND BIOMECHANICAL STUDY THE CONDITION OF BLOOD VESSELS FEEDING THE BRAIN

Cardiovascular diseases are the leading cause of death in the world. A serious problem of modern medicine is the creation of effective methods of treatment and prevention of cardiovascular diseases. Mathematical modeling and numerical calculations of blood flow in a network of vessels with pathologies play an increasing role in their development. They allow to predict surgical operations, to optimize the form of implants, to investigate their effects on hemodynamics. The article discusses the development of algorithm and methodology for assessment of blood vessels that feed the brain is normal, the pathological changes and the correction. To implement this: 1) built a conceptual model of brachiocephalic arteries that supply the brain; 2) sections of computer tomograms built computer geometrical models of the blood vessels of the patients; 3) constructed computer models and the analysis of the flow of blood flow in blood vessels; 4) an analysis of the impact of atherosclerotic deposits on the hemodynamics in the circle Millisievert; 5) an algorithm and a method of studying the stress – strain state of blood vessels during dilation and stenting have been developed. The results of the study can be used as an additional diagnostic tool in the analysis of cerebral circulation in specific anatomical cases or in the case of planning operations with blockage of several arteries.
