[Urokinase in a premature infant: its use in a case of right atrial thrombosis secondary to catheterization of the umbilical vein]. / Urochinasi nel prematuro: utilizzo in un caso di trombosi atrial destra secondaria a cateterizzazione della vena ombelicale.

ABSTRACT

Newborns with vascular catheters must be investigated by echocardiogram for intracardiac thrombosis. We report the use of urokinase to treat an asymptomatic right atrial thrombus in a 31 weeks' gestation newborn; the thrombosis occurred after placement of a catheter in the umbilical vein. We obtained a safe and successful thrombolysis using urokinase 4000 U/kg/h in continuous infusion.
