  • Title: Percutaneous angioplasty for renovascular hypertension due to fibromuscular dysplasia.
    Author: McAllister MD, Thompson WC, Pabian CJ.
    Journal: Am Fam Physician; 1992 Oct; 46(4):1225-30. PubMed ID: 1329461.
    Abstract:
    Because the cause of hypertension is reversible in only 5 percent of patients, extensive initial work-up should only be considered in selected cases. Secondary causes should be suspected in patients whose hypertension begins before age 30 or after age 50 and in patients whose hypertension suddenly worsens after a long period of good control, becomes severe or malignant, or remains refractory to maximal medical therapy. A sudden reduction in renal function in a hypertensive patient and the discovery of a unilateral small kidney may also raise suspicion of a secondary cause. Renovascular disease, one of the most common secondary causes of hypertension, is usually the result of atherosclerosis in older patients and the result of fibromuscular dysplasia in younger patients. Physical examination seldom contributes to the diagnosis. The classic upper abdominal or flank bruit occurs in only 30 to 50 percent of patients with renovascular disease, and is not uncommon in patients with essential hypertension. The gold standard for diagnosis of renovascular disease remains the arteriogram. Transluminal renal angioplasty may be performed during arteriography if a high-grade stenosis is identified. Other management options include medical therapy and surgical revascularization with grafts.
