Things to Know About Stent Implantation
In most cases, stent placement is performed together with the balloon angioplasty procedure. A stent may be a small metal mesh tube that acts as a skeleton to produce support within the arteria. A balloon catheter advanced over the guidewire is employed to position a stent within the narrowed artery. When the stent reaches the narrowed area, the balloon is inflated and therefore the stent expands in accordance with the diameter of the artery and attaches to the vessel wall. After the balloon is deflated, the stent remains permanently at the purpose where it had been placed. Within some weeks, the stent heals by being covered with normal vascular cells (endothelium). Angioplasty with a stent is typically recommended for patients with narrowing or occlusion of 1 or both coronary arteries. If there's a blockage in addition to two coronary arteries, artery bypass surgery could also be considered.
