title: Aortic anomalies in an adolescent with the Williams' elfin facies syndrome.
abstract: An adolescent with classical Williams' syndrome who presented with hypertensive encephalopathy is described. He had the unusual combination of supravalvular aortic stenosis, long segment coarctation of the aorta, aortic hypoplasia and a high bifurcation of the abdominal aorta. Surgical resection of the coarctation was required; however, the patient has remained moderately hypertensive. The aortic anomalies in this syndrome are reviewed and their frequency and importance examined.
