Role of diagnostic renal arteriography in children with suspected secondary hypertension

The incidence of pediatric hypertension (HTN) is on the rise alongside the obesity epidemic in developed countries due to the increased incidence of essential/primary HTN in children [1]. However, secondary HTN should be considered, particularly in lean, prepubertal children with blood pressure exceeding the 95th percentile for age by more than 12 mmHg (stage 2 HTN). Renal parenchymal disease and renovascular disease are the leading causes of secondary HTN [1] in children and warrant thorough investigation.
