Abstract:
The incidence of primary (i.e. essential) hypertension in children and adolescents is increasing; however, secondary hypertension, with an identifiable cause, remains relatively common and might be treatable or even curable. Renovascular hypertension is an uncommon but important secondary cause of hypertension in the pediatric population that can be associated with substantial morbidity. In this article we discuss renin-mediated causes of hypertension in children and related complications, review renal Doppler ultrasound techniques for the evaluation of renin-mediated hypertension (including both direct and indirect assessments), and briefly appraise the literature pertaining to renal Doppler ultrasound and the assessment of pediatric hypertension. Finally, we describe a proposed role for renal Doppler ultrasound in the workup of suspected renin-mediated hypertension in children and adolescents.
