Thirty-two children (median age 5.9y, 12 male, 18MM, 14 OCVD) were included. Clinical presentation was arterial ischaemic stroke/transient ischaemic attack in 30, with cerebral infarction in 29. 5 had also clinically presented with hypertension. Renovascular abnormalities were identified in 16 patients - main renal artery (RA) stenosis in 10 (6 OCVD, 4MM), branch RA abnormalities in 5 and peripheral abnormalities in 9. 6 children had multi-site abnormalities. There was no significant difference in the frequency of main RA disease in the MM and OCVD groups (p = 0.21). Of the 27 children with purely neurological presentations; main RA stenosis was seen in 5 and branch/peripheral abnormalities in 10. 5 children had multi-site abnormalities. Based on a median of 5 SBP readings/patient 14 met the definition for HT. Overall BP was poorly recorded and had never been plotted on centile charts in these patients.
