Renovascular disease (RVD) is responsible for 5.8% of secondary hypertension cases in young adults, caused mainly by obstructive lesions due to either atherosclerotic renal artery stenosis or fibromuscular dysplasia. Although the renal arteries’ supradiaphragmatic origin is exceedingly rare, up to date, three cases of secondary hypertension due to single ectopic renal arteries originating from the thoracic aorta have been reported in patients with customarily positioned kidneys. Herein we describe a case of a 21-year-old man with resistant hypertension whose investigation showed an ectopic right renal artery originated from the internal thoracic artery. Although both renal arteries were free of obstructive lesions, the right one was very long and tortuous, causing kidney hypoperfusion. A bypass surgery between the right renal artery and the aorta was performed uneventfully, leading to better blood press control. To the best of our knowledge, there are no previous reports of secondary hypertension due to renal artery arising from the internal thoracic artery.
