Duplex Evaluation of the Renal Arteries

  • Marsha M. Neumyer

Abstract

Hypertension is estimated to affect approximately 60 million people in the United States1 and it is thought that 1–6% of this group will have underlying renal disease as a cause of their hypertension.2,3 The true prevalence of disease is unknown and varies with the population studied. It has been shown that in selected patient populations the prevalence of renal artery stenosis is in the range of 20–50% and that progression of stenosis may occur in 30–50% of patients.4,5 Renal artery stenosis is more likely to be found in those with severe hypertension and in hypertensive children. The long-term prognosis for patients with renovascular hypertension is worse than that of patients who do not have renovascular lesions, but it must be recognized that renal artery disease is the most curable cause of hypertension.
