Abstract
Atherosclerotic renovascular disease is the most important cause of secondary hypertension. The natural history of the disease reveals progression rates of 4 to 12% per year. Angioplasty with renal artery stenting is one treatment option; but there are few studies that have reported long-term results. The objective of this systematic literature review is to discuss the long-term results (at least 24 months) of angioplasty with stenting of renal arteries for atherosclerotic disease, in terms of renal function and blood pressure levels for control of hypertension. A thorough search was conducted of LILACS, EMBASE, SCIELO, Cochrane Library, and MEDLINE using the appropriate terms. Just seven out of 2170 references identified met all inclusion criteria. It was concluded that over the long term renal function was stabilized, blood pressure levels were reduced, and the number of classes of antihypertensive medication decreased.
