Three-dimensional visualization of renal artery stenosis by 64-channel multiple detector-row computed tomographical angiography: review of two paediatric cases.
Three-dimensional visualization of renal arteries has recently been established by helical contrast-enhanced multiple detector-row computed tomographical angiography (MDCTA) in adults. So far, no information is available on its use in children. We reported two children with renal artery stenosis detected by 64-channel MDCTA. The first patient probably had fibromuscular dysplasia and the other neurofibromatosis type 1. The technique showed a left renal artery stenosis with a small left kidney in the first patient and a right renal artery stenosis in the second.


CONCLUSIONS
MDCTA is an accurate and noninvasive imaging technique, easily performed in children, and can be used as an alternative diagnostic modality in children with suspected renovascular hypertension.
