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] Stents may help maintain the effects of angioplasty.
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]
