Stenting is a medical procedure used to open narrowed or blocked blood vessels, often in the heart. A small, mesh-like tube called a stent is inserted into the affected area to keep the vessel open, allowing for improved blood flow. This procedure is commonly performed during angioplasty, where a balloon is used to expand the narrowed vessel before placing the stent. The stent remains in the body permanently and is typically made of metal or polymer materials. It helps prevent the vessel from re-narrowing, reducing the risk of serious conditions like heart attacks. Stenting is a minimally invasive option compared to traditional surgery.
