Management of atherosclerotic renal artery disease in younger patients.
From 1970 to 1990, 57 patients 50 years old or younger were treated for hypertension caused by atherosclerotic renal artery disease. Predisposing factors for atherosclerosis included smoking in 43 cases, hyperlipidemia in 15, diabetes in 8 and hyperuricemia in 8. Of the patients 47 had a family history of atherosclerotic vascular disease or a significant related disorder. Evidence of generalized atherosclerosis was present in 55 patients. Atherosclerotic renal artery disease was present unilaterally in 16 cases, bilaterally in 39 and in a solitary kidney in 2. Of the patients 34 were treated surgically, 20 medically and 2 by percutaneous angioplasty. Surgically treated patients experienced significant postoperative improvement in blood pressure (p = 0.001) and renal function (p = 0.05). Medically treated patients experienced significant improvement in blood pressure (p = 0.03) but renal function deteriorated. Younger patients with atherosclerotic renal artery disease suffer from a more severe and accelerated form of atherosclerosis than older patients. Although blood pressure control can be achieved with medical treatment, surgical revascularization offers the best opportunity for stabilization or improvement of renal function.
