A 29-year-old woman with refractory hypertension who previously suffered from subarchnoid hemorrhage visited our facility. The diagnosis of renovascular hypertension due to fibromuscular dysplasia was made based on a high level of plasma renin activity (PRA) and aldosterone concentration (AC), and computed tomographic image of bilateral renal artery stenosis/obstruction. Angioplasty, which could be performed only to the left renal artery, failed to regain suffcient BP control. The addition of eplerenone, an aldosterone receptor blocker, to the conventional antihypertensive drugs successfully and safely lowered BP and preserved the renal function despite the persistence of high PRA and AC values.
