Abstract

Article presents results of the numerical study concerning nature of blood flow in the post-surgical artery. The research focuses on the development of geometric variants of patches sewn into the common carotid artery during surgery of the atherosclerotic plaque removal. Based on analytical methods, the geometry of the patch described by the polynomial function has been developed. The simulations of blood flow in the arteries with the sewn patch were performed. The study includes the influence of the patient’s diameter, the width and length of the chosen patch on blood flow disorders. The study results comprise the development of software that with the use on input data related to arterial geometry, patch length and patient’s blood parameters (affecting the fluid density and viscosity), shall generate an accurate contour of the patch of width in the selected range.
