"angioplasty" 的定义和意义

What is "angioplasty"?

Angioplasty is a medical procedure used to widen blood vessels that are narrowed or blocked. During angioplasty, a thin tube with a balloon on its tip is passed through a blood vessel to the affected area. The balloon is then inflated to push the blockage against the vessel walls, widening the artery and restoring blood flow. In some cases, a stent, which is a a small mesh tube, may be inserted to keep the artery open. Angioplasty is commonly performed to treat conditions like coronary artery disease, peripheral artery disease, and certain types of strokes. It helps improve blood circulation and reduce symptoms such as chest pain or leg pain caused by reduced blood flow.
