Aortic stents are maintained for about 10 to 20 years. Aortic stents are tubular devices used to restore blood flow in the human body by supporting stenotic or occluded blood vessels due to disease, either permanently or temporarily. Aortic stenting refers to the placement of an endoprosthesis in the diseased segment to support the stenotic and occluded segment of the blood vessel on the basis of balloon dilatation and molding of the lumen to reduce the elastic retraction of the blood vessel and remodeling, to achieve the purpose of maintaining a smooth blood flow in the lumen, improving the stenosis of the blood vessel, protecting the plaque and preventing cerebral infarctions, which usually lasts for 10 to 20 years. The fact that aortic stenting lasts for a long time does not mean that the survival rate after aortic stenting can be up to 10 or even 20 years. The number of years of aortic stent use is not necessarily related to life expectancy, and it can usually be used for a lifetime with regular post-procedure follow-up and maintenance therapy. After aortic stenting, it is important to control blood pressure and heart rate, quit smoking and drinking, use aspirin and other medications to control blood aggregation and prevent the formation of blood clots that can block blood vessels, and maintain a healthy lifestyle with less greasy and fried foods, such as fried cakes.
