Angioplasty is a procedure used to open up arteries that are affected by atherosclerosis or plaque. This is done to restore the blood supply and treat and prevent problems like heart attacks. There are 500000 coronary angioplasties every year. Atherectomy, a related procedure, is done to remove plaque from the wall of an artery. The procedure costs about $20000.
Angioplasty is often done at the same time as placement of an arterial stent, especially for treatment of the coronary arteries.
In some cases, a stent is used to hold an artery open. This is most often used in the coronary (heart) arteries, but it is sometimes used in the aorta, the renal (kidney) arteries, the iliac (leg) or the cerebral arteries. About 500000 stent procedures are done every year, and the cost of a stent placement is about $18000. The stent itself is also expensive, and the cost of this varies depending on its size and its function.
