Atherosclerotic renovascular disease: diagnosis and treatment

The technical expertise and tools required to treat renovascular obstruction have become commonplace, and many series of patients revascularized with surgery, balloon angioplasty or endovascular stenting have been reported, Nevertheless, although hypertension and renal failure are easy to diagnose, their cause often remains elusive, Evidence is developing that patients with hypertension and atherosclerotic renal artery stenosis may often have hypertension and renovascular disease but not hypertension because of renovascular disease. As a result, diagnosis and therapy are increasingly directed towards the preservation of renal function, and the future of renal revascularization will depend on how well potential therapies address this goal, Curr Opin Nephrol Hypertens 9:659-668.
