Renal artery stenosis is one of the secondary causes of pediatric hypertension. Cases with critical unilateral renal artery stenosis associated with the middle aortic syndrome are rare phenomena. The middle aortic syndrome (MAS) is a rare vascular disease representing an important cause of severe hypertension in children. MAS are mostly idiopathic, but also may occur in genetic and acquired disorders.
