We report a case of severe hypertension in a girl with no evidence of parenchymal renal disease. Arteriography revealed segmental stenosis and a saccular aneurysm affecting a branch of the left renal artery. Segmental renal vein renin sampling demonstrated a markedly increased rate of renin secretion from the ischemic portion of the left kidney. Partial… CONTINUE READING
