The advent of vascular stents is an important development in the treatment of coronary artery stenosis, which can overcome the lack of balloon dilatation in the past. In the past, when the patient’s blood vessels were narrowed from the cardiac catheterization examination, most of them were undergoing coronary artery bypass surgery until balloon expansion was started more than 30 years ago. The atherosclerotic plaque is flattened, but because of its pathological effect, about 3 to 5 percent will appear stenosis within half a year. In order to overcome this deficiency, the medical community later added a net-like metal substance to the balloon to support the blood vessel. The balloon is then removed, leaving a metal stent to hold the narrow lesion in the lumen of the blood vessel. At present, many people install cardiovascular stents to clear the bloodway.
