The　hemodynamics　simulations　of　the　aortic　arch,　S-shaped　curved　artery,　carotid　artery,　abdominal　artery,　etc.　were　analyzed.　Hemodynamics　simulations　of　arterial　stenosis　and　its　bypass　graft　treatment,　arterial　aneurysm　and　its　endovascular　stent　treatment,　aortic　dissection　and　its　bypass　graft　treatment　were　discussed.　Hemodynamics　not　only　plays　a　crucial　role　in　the　initiation　and　development　of　arterial　pathological　changes,　but　also　is　a　noteworthy　factor　which　should　be　considered　in　the　procedures　of　surgery　and　intervention　treatment　of　cardiovascular　diseases.　Hemodynamics　simulation　has　become　an　assistant　decision-making　tool　for　the　treatment　strategy　of　cardiovascular　diseases,　and　can　provide　instructions　of　surgical　planning　for　surgeons.
