Newborn with an Intracardiac Mass Generated Secondary to Umbilical Vein Catheterization

Abstract

Umbilical vein catheterization is a routine procedure of neonatal intensive care units, and only rare complications associated with catheter malposition have been described in the literature. We herein present an infant boy (28 days old, 4 kg) with an intracardiac mass diagnosed after umbilical vein catheterization. The patient was referred to our clinic with a diagnosis of catheter migration and thrombosis, but this could not be confirmed during surgery. Pathological analysis of the excised intracardiac mass revealed nonbacterial thrombotic endocarditis. Our case confirms the essentiality of controlling the location of the umbilical venous catheter after its insertion.
