  • Title: A Unique Case of Renovascular Hypertension due to Fibromuscular Dysplasia in an Extra-renal Artery.
    Author: Sakuma I, Saito J, Matsuzawa Y, Omura M, Matsui S, Nishikawa T.
    Journal: Intern Med; 2018 Sep 15; 57(18):2689-2694. PubMed ID: 29709926.
    Abstract:
    A 33-year-old man was admitted to our hospital to undergo an evaluation to determine the cause of secondary hypertension. Computerized tomography angiography (CTA) showed bilateral multiple renal arteries with significant stenosis of the right extra-renal artery due to fibromuscular dysplasia and segmental impairment of renal perfusion. Although the plasma aldosterone concentration and plasma renin activity were within the normal ranges, percutaneous balloon dilatation of the stenotic lesion resolved his hypertension, leading to a diagnosis of renovascular hypertension caused by segmental renal ischemia due to extra-renal artery stenosis. CTA should be considered during the examination of patients with early-age hypertension, even if the plasma renin activity is not sufficiently elevated.
