[Transumbilical aortography in the newborn infant with abdominal tumor]

The use of the umbilical vessels to perform angiographic studies in the neonatal period, has been previously mentioned. In this paper, we present our experience in the use of this route to carry out aortography in the study of abdominal tumors. This method was performed in the last 2 years in 7 patients, ages 1 to 10 days. The procedure is easy and of low cost and practically without complications if properly applied. We have now another method to evaluate abdominal masses in the newborn.
