The clinical characteristics and outcomes of children with mid-aortic syndrome (MAS) and the effectiveness of different therapeutic approaches in reducing hypertension are still debated. We conducted a single-centre retrospective review of the records of children with MAS over 30 years. Children with angiographic evidence of a narrowed abdominal aorta were included. Therapeutic approaches included medical management, percutaneous transluminal angioplasty and/or surgical intervention. Thirty-six children had presented at a median age of 2.7 years (10 days–10 years). Thirteen (36%) patients had associated syndromes, and 44% had been diagnosed with cerebrovascular disease. All patients had involvement of multiple arteries. The mortality rate was 8% after a median follow-up period of 4.5 (range 1.1–19.7) years. Among the children who survived, 90% had obtained a reduction in their blood pressure (BP). Of the patients, 76% had had a normal estimated glomerular filtration rate (eGFR) at the last follow-up examination. Seventeen percent (six of 36) had renal dysfunction at presentation. Although MAS is a severe and widespread disease, in most cases it can be effectively treated with a combination of medical, angioplasty and surgical interventions.
