title: A human umbilical cord with four arteries.
abstract: An unusual case of a newborn infant with four umbilical arteries is presented. Multiple catheterizations revealed that triplication of the right umbilical artery was responsible. There were no associated malformations, and follow-up at 9 months of age revealed age-appropriate growth and development. This case extends the spectrum of observable umbilical artery anomalies.
