[Thrombosis of the right atrium after umbilical venous catheterization. Favourable outcome after early thrombectomy].

A case of right atrial thrombosis after venous umbilical catheterization in a 21 day-old premature newborn is reported. The initiating factors of such an accident and its clinical signs are evocated. The authors emphasize the value of a systematic ultrasonographic supervision of newborns with central catheters for a long period of time and the value of surgical thrombectomy.
