Case reports Successful percutaneous angioplasty of renal artery in a patient with severe arterial hypertension and symptoms of hyperaldosteronism: a case report

Abstract

Arterial hypertension may result from renal artery stenosis. In this type of hypertension renin-angiotensin-aldosterone system is activated and patients often produce signs of hyperaldosteronism. It must be distinguished from primary hyperaldosteronism in order to chose a proper therapy. In this paper we describe a case of a 65-years-old man with severe arterial hypertension, which was difficult to control pharmacologically. The patient revealed symptoms which suggested primary hyperaldosteronism (except normal plasma renin activity). Only imaging techniques allowed diagnose of renal artery stenosis and carry out successful percutaneous angioplasty of renal artery.
