Abstract: 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.
