Usually, the service life of the coated stent is for the lifetime of the patient. The overall shape of the stent is cylindrical, and the metal stent is coated with a special membrane material, which combines the characteristics of metal structure and membrane material. The membrane stent can be applied to important blood vessels throughout the body, such as coronary arteries, iliac arteries, lower limb arteries and thoracic and abdominal aortas. Because of its membrane-like surface, blood does not extravasate into normal vessels as it passes through the stent. Therefore, the peritoneal stent is more suitable for perforating vascular lesions including aortic coarctation, abdominal aortic aneurysm, thoracic aortic aneurysm, and coronary artery dissection. The peritoneal stent is accompanied by the patient for life if there is no infection or displacement, otherwise it needs to be replaced in time. It is recommended that patients consult regular hospitals in a timely manner, and standardize treatment under the guidance of doctors to avoid delays.
