Renal sonography with Doppler for detecting suspected pediatric renin-mediated hypertension - is it adequate?

Background: Renal Doppler US is used to evaluate suspected vascular causes of hypertension in children, despite mostly unknown diagnostic performance characteristics.

Objective: To evaluate renal Doppler US for detecting vascular causes of hypertension in children with high clinical suspicion of aortic or renal artery narrowing.

Materials And Methods: We identified pediatric renal Doppler US examinations performed for hypertension between January 1995 and June 2010 at our institution.

Imaging of renin-mediated hypertension in children.

Objective: The purpose of this article is to review the imaging findings of common and uncommon causes of renin-mediated hypertension in children using a multimodality radiologic approach.

Conclusion: Pediatric hypertension, although uncommon, is often due to aortic or renal artery narrowing. Imaging plays an important role in the diagnosis and characterization of pediatric renin-mediated causes of hypertension.
