title: The radiological evaluation of children with hypertension.
abstract: The value of radiological examinations in hypertension was analyzed in a series of 44 children. An i.v. urography had been performed in 43 cases with a pathological finding in 19 (44%). Renal angiography, employed in 19 cases, revealed abnormal findings in 12 (63%) patients. Micturating urethrocystography performed in 16 children gave no additional important information. The only complication noted was thrombosis of the femoral artery subsequent to renal angiography in one child less than one year of age. The diagnosis of hypertension based mainly on the i.v. urography in 12 cases but the renal angiography gave additional important information in 6 children. One child with obstructive hydronephrosis was also found to have a renal artery stenosis at renal arteriography. Based on these results, and particularly because secondary hypertension may frequently be treated surgically, we consider extensive radiological investigation with renal angiography is mandatory before receiving a final diagnosis of essential hypertension, and before starting long-term treatment.
