“…However, there is no consensus on the preference for bypass surgery or stenting. Researchers like Christian Heiss et al [6] , Michael S. Conte [7] , Katarina Björses et al [8] , and Yulanka Castro Dominguez et al [9] have conducted studies on arterial vessels using FLUENT software; Nadeem et al [10] and M. Timofeeva et al [11] have investigated the flow behavior of blood in narrowed arteries using FLUENT software; Bakhyt Alipova et al [12] utilized CFD simulation to examine pulsatile flow within arteries; Konstantinos G. Lyras et al [13] and Tirivanhu Chinyoka et al [14] analyzed the accuracy of CFD simulations under various geometric conditions; Gianna E. Karanasiou et al [15] used FLUENT software to analyze blood flow characteristics after stent implantation, and Panagiotis Parissis et al [16] used FLUENT software to study blood flow characteristics after bypass surgery. This paper considers hemodynamic aspects to simulate the two types of flow field distributions post-operation using the finite element software ANSYS FLUENT, analyzing the impact of reflux and other factors on eddy flow [17] .…”

In recent years, Computational Fluid Dynamics (CFD) simulation software has become increasingly prevalent in the study of hemodynamics. The choice between artery bypass and stent surgeries has long been a subject of debate within this field. This paper use ANSYS FLUENT for numerical simulations to investigate the flow dynamics post-surgery, aiming to compare the advantages and disadvantages of these surgical methods and thus inform decision-making for medical professionals. The simulations reveal that post-artery bypass surgery, blood flow near the vessel wall is accelerated while it slows in the central region, which could effectively mitigate atherosclerosis. However, due to external pressure on the vascular adventitia, the internal diameter in the stent region is reduced compared to a normal vessel, leading to a highspeed flow area within the stent that enhances blood circulation. Ultimately, the choice of surgical intervention should consider the patient's specific conditions, including age, disease duration, and severity, to determine the most suitable approach. It's crucial to recognize that surgery is merely one component of treatment; adopting healthy lifestyle habits is essential to prevent the recurrence of vascular blockages.
