Acquired coarctation of the abdominal aorta related to umbilical artery catheterization.

Severe hypertension is rare in children, and often has a secondary cause. We review a case of a five year-old boy who presented with severe hypertension secondary to an acquired coarctation of the abdominal aorta. We hypothesize that this lesion resulted from endothelial damage caused by umbilical artery catheterization as a neonate.
