Abstract
This case report describes a newborn with pulmonary hypertension who developed liver failure and multi organ failure due to extravasation through a malpositioned umbilical venous catheter. Although this procedure is commonly used, correct positioning is difficult, particularly since x-ray confirmation is unreliable. Acceptance in suboptimal position, not at the junction of the inferior vena cava and the right atrium, can lead to serious morbidity and mortality. With this case report we want to raise awareness of the risk of complications following improper tip placement of an umbilical venous catheter and promote the use of ultrasound in confirming the catheter position
