title: Coexistence of atherosclerotic renal artery stenosis with primary hyperaldosteronism.
abstract: The discovery of two forms of secondary hypertension in the same patient is unusual and suggests similar pathophysiological mechanisms, a predisposition to one type in the presence of the other or a chance occurrence. We describe two patients with renal artery stenosis who after successful correction of the stenotic lesions were discovered to have primary hyperaldosteronism associated with bilateral adrenal hyperplasia. Initially prior to revascularisation of the renal artery stenosis, the diagnosis of primary hyperaldosteronism was not evident. Both patients were subjected to further diagnostic evaluation after the appearance of hypokalaemia in one patient and continued resistant hypertension in both patients. The addition of spironolactone therapy reduced blood pressure impressively in both patients. Clinicians should be aware of the possibility that these two forms of secondary hypertension may be present in the same patient and that optimal blood pressure control requires diagnostic assessment and intervention for both disorders.
