Angioplasty, either with or without stenting, is a minimally invasive procedure. When a vein or artery is too narrow due to stenosis or blocked, angioplasty is utilized to open the area and allow normal blood flow.
X-ray imaging is used to guide a balloon-tipped catheter (a long, thin plastic tube) into the area where it is narrowed or blocked. The balloon is then inflated to open the vessel to normal size, then it is deflated and removed.
