In medicine, angioplasty is "endovascular reconstruction of an artery, which may include the removal of atheromatous plaque and/or the endothelial lining as well as simple dilatation. These are procedures performed by catheterization. When reconstruction of an artery is performed surgically, it is called endarterectomy."[1]
Angioplasty may be used to treat coronary heart disease, renal artery stenosis, and carotid stenosis. Angioplasty of the heart is called percutaneous transluminal coronary angioplasty.
As compared to surgery:
- Angioplasty is probably better than surgery for renal artery stenosis. Surgery leads to improved patency rates at 4 years (88% versus 68%); however, angioplasty improves renal function and tends to have less mortality after 4 years (18% vs 25%).[2]
- Angioplasty is less effective than surgery for myocardial revascularization of coronary heart disease[3], especially for patients with diabetes who have stenosis of three coronary arteries.[4] Angioplasty did not include stents in this study.
- For carotid stenosis, angioplasty with stents have less short term effect, but similar intermediate term effect as carotid endarterectomy.[5]
