Stent placement is a medical procedure used to open narrowed or blocked blood vessels, often due to atherosclerosis. A stent is a small, mesh-like tube that is inserted into the affected area to keep it open, allowing for improved blood flow. This procedure is commonly performed during angioplasty, where a balloon is used to expand the vessel before the stent is placed. The procedure is typically done in a hospital setting and may involve local anesthesia. After the stent is positioned, it remains in the body permanently, helping to prevent future blockages. Patients usually recover quickly and can return to normal activities within a few days.
