Coated stent usually refers to a metal stent coated with a special membrane material, and is often used for abdominal aortic aneurysm coated stent implantation.
As the biggest complication of abdominal aortic aneurysm is the possibility of rupture, and the membrane stent can greatly reduce the risk of rupture of the aneurysm, which not only retains the function of the metal stent, but also has the characteristics of the membrane material, after abdominal aortic aneurysm implantation of membrane stenting can be very good to reduce the pressure of the aneurysm, so that the blood can be smoothly passed from the membrane to the distal end of the blood flow.
At present, abdominal aortic aneurysm overlay stent implantation has been developed more mature, and less traumatic, can be applied to most abdominal aortic aneurysm patients.
