To characterize the clinical and angiographic features in children with renovascular hypertension. Clinical data of 14 children (7 male, 7 female; age 0.8-14 years, mean 8.7 years), who were diagnosed with renovascular hypertension by renal angiography in our institute from January 2005 to December 2012 were collected and retrospectively analyzed. The mean blood pressure at the diagnosis was 187/127 mm Hg. Chief complaints of symptomatic patients were headache (29%, 4/14), hypertensive encephalopathy (36%, 5/14), signs of congestive heart failure (14%, 2/14) and hematemesis (7%, 1/14). Renovascular hypertension was found incidentally in 14% (2/14) of patients who were asymptomatic. Conventional renal angiography elucidated the anatomical distribution of lesions in the renal arterial system. It was found that 14% (2/14) of patients had bilateral disease, 50% (7/14) had single stenosis at main or accessory renal artery, while multiple stenoses was seen in 43% (6/14) of children, with involvement of segmental re
