Current concepts in renovascular hypertension.
Renovascular disease represents an important dimension of hypertension. Although estimates vary regarding the exact prevalence of renovascular hypertension, it is being diagnosed with increasing frequency because of refined criteria for the workup and the availability of sensitive diagnostic tests. Two major pathologic entities--atherosclerosis and fibromuscular dysplasia--account for most cases of renovascular hypertension. Once the diagnosis and clinical significance of renal artery stenosis in a hypertensive patient are established, appropriate and specific therapy should be considered. The goal is not only to treat hypertension, but to preserve and restore renal function. Although antihypertensive drug therapy may lower the blood pressure, reperfusion of the kidney (surgical, angioplasty) is a desirable long-term objective in the management of patients with renovascular hypertension. With careful selection of therapeutic choices, we are now able to render optimal care to patients with renovascular hypertension.
