[Peripheral arterial catheterization in neonates and infants. Remote study of the arterial permeability by the Doppler effect]. / Cathétérisme artériel périphérique chez le nouveau-né et le petit nourrisson. Etude à distance de la perméabilité artérielle par effet Doppler.

ABSTRACT

Nineteen peripheral arteries were examined by Doppler US 1 month to 2 years after their catheterization. Two of them were completely obstructed and 4 showed signs of arterial stenosis. No functional repercussion was observed. This minor risk seems low as compared to the advantages of the technique.
