Computer Modeling of Carotid Endarterectomy With the Different Shape Patches and Prediction of the Atherosclerotic Plaque Formation Zones

The article describes a method for con-structing geometric models of the carotid bifurcation and computer simulation of endarterectomy surgery with the patches of various configurations. The pur-pose of this work is to identify the areas of the greatest risk of restenosis in the constructed models and to con-duct a comparative analysis of risk factors when using the patches of different widths and shapes. The method is demonstrated on a reconstructed model of a healthy vessel. Its building is based on a preoperative com-puted tomography study of a particular patient's affected vessel. The flow in the vessel is simulated by computational fluid dynamics using data from the patient's ultrasound Doppler velocimetry. Risk factors are assessed through the hemodynamic indices on the
