Zusammenfassung:Arterial thromboembolism in the pediatric population frequently occurs secondary to arterial catheterization. Catheterization-related complications are more common in smaller and sicker infants, due to high prothrombotic activity, low levels of natural anticoagulants, and various fibrinolytic imbalances. Arterial thrombus management in neonates remains controversial. Recombinant tissue plasminogen activator is the most commonly used thrombolytic agent in children, however there is very little experience with recombinant tissue plasminogen activator therapy in small prematures, especially in the first week of life. This case study reports catheter-related femoral artery occlusion in an extremely low-birth-weight preterm infant. Despite continuous heparin infusion for 6 hours, no resolution of the thrombus was seen by clinicians. Heparin was stopped, and recombinant tissue plasminogen activator therapy enabled complete recovery from the thrombus. The risk of bleeding (including intracranial hemorrhage) with recombinant tissue plasminogen activator treatment, especially in small preterm neonates is unknown. However, in this extremely low-birth-weight preterm infant, recombinant tissue plasminogen activator therapy was effective, and limiting the infusion rate to ≤0.4 mg/kg/hour was safe.
