Stenting is a medical procedure in which a small, mesh-like tube called a stent is placed in a narrowed or blocked blood vessel to help keep it open. This procedure is commonly used in the treatment of conditions such as coronary artery disease, peripheral artery disease, and kidney stones. Stenting can help improve blood flow and relieve symptoms associated with blocked or narrowed arteries. The stent can be made of various materials such as metal, plastic, or fabric, and can be placed through minimally invasive techniques using a catheter. Stenting is a relatively safe and effective treatment option for many patients with vascular diseases.
