    Abstract Background: Renovascular hypertension (RVH) can be caused by renal artery stenosis (RAS) and/ or middle aortic syndrome (MAS).
    Methods: Patients who received surgical or transcatheter treatment for RVH between 1/1991 and 11/2017 were retrospectively reviewed using age = adjusted blood pressure ratio (BPR).
    Results: Fifty-three patients diagnosed with RVH at a median age of 4.5 (0–18) years were included. Vascular involvement ranged from MAS with RAS (20), RAS only (32), and MAS only (1). The first intervention was transcatheter in 47 patients (transcatheter group: angioplasty = 41, stenting = 5, and thrombectomy = 1), and surgical in 6… More >
