Mid aortic syndrome (MAS) is characterized by an extensive narrowing of the abdominalaorta, with involvement of the renal and visceral arterial branches. Angiography is the goldstandard for the diagnosis of MAS. However, computed tomography angiography (CTA) caneffectively determine the location and the extent of the stenosis. Medical management ofMAS generally means a lifelong, combination of multiple classes of antihypertensivemedications. Surgical correction such as aortoaortic bypass with renal revascularization remainsthe definitive treatment of the idiopathic MAS. Moreover, the surgery can provide tissues forhistological examination to arrive at the definite diagnosis of MAS. We reported a case ofMAS in a child with discrepancy of the blood pressure in the upper and lower extremitiesalong with abdominal bruits. The diagnosis of MAS was confirmed by the CTA. Her bloodpressure was controlled with 6 antihypertensive drugs with no serious side effects observed.
