Abstract:

Introduction: Mid-Aortic Syndrome (MAS) is a rare vascular malformation characterized by segmental narrowing of the abdominal aorta and stenosis of its principal branches. Patients affected by MAS typically present malignant renovascular hypertension, with variable clinical symptoms like claudication, abdominal angina, and headache. Moreover, they can develop other complications, such as hypertensive encephalopathy, congestive heart failure and vascular brain accidents. Hypertension with MAS is often resistant to multidrug therapy, requiring a surgical approach to treat the clinical symptoms, prevent or block organ damage and normalize the blood pressure.

Case report: Here, the case of a 4-year-old boy showing elevated blood pressure with left ventricular hypertrophy leading to idiopathic MAS, who was successfully treated with percutaneous transcatheter renal angioplasty (PTRA) using an unusual, anterograde access, is reported.

Discussion and Conclusion: In children and adolescents, vascular malformations like MAS must be considered as a possible cause of hypertension. PTRA is a successful therapeutic strategy in children with severe renovascular hypertension. Anterograde access, using an axillary artery, can be a valid approach for PTRA when femoral access is difficult to achieve.
