To determine the location and distribution of renal artery stenosis in children with renal vascular hypertension demonstrated by renal angiograms.

We reviewed all renal angiograms performed on pediatric patients presenting specifically with hypertension from February 19, 1993 through April 13, 2005. A total of 84 patients were identified from which 39 had abnormal angiographic findings. Patients with systemic vascular disorders or syndromes, prior renal bypass vascular grafts, and renal transplants were excluded. In total, we reviewed the records of 21 patients to record the location of the renal artery stenoses.

21 patients (12 male: 9 female) were included between the ages of 30 months and 18 years (mean 9 years 3 months). In these patients a total of 24 stenoses were reported. 6 (25.0%) stenoses were located in the main renal artery, 12 (50.0%) were in secondary renal artery branches, 3 (12.5%) were in tertiary renal artery branches, and 3 (12.5%) stenoses were located in an accessory renal artery or branches off the accessory artery. Of the 6 stenoses in the main renal artery there was a single ostial lesion, 4 proximal stenoses, and a single distal lesion. 19/21 patients had a single stenotic lesion each. A single patient had 2 stenoses while another patient had 3. The stenoses were equally distributed bilaterally (12 right: 12 left).

The vast majority (75.0%) of renal artery stenosis in hypertensive children without associated systemic vascular disorders or syndromes do not occur in the main renal artery.
