Answer

The consequences of renal artery stenosis are hypertension, which may be particularly difficult to control or may require multiple antihypertensive agents (with increased adverse effects), and progressive loss of renal function (ischemic nephropathy).

In addition, the discovery of atherosclerotic renal vascular disease (RVD) frequently occurs in the setting of generalized vascular disease (ie, cerebral, cardiac, peripheral), with the co-morbidity associated with disease in those vascular beds. Thus, any therapeutic intervention for renal artery stenosis should logically take into account the underlying prognosis associated with these co-morbidities.
