Objectives Umbilical venous catheterization is commonly used in the neonatal period; however, it has some complications. In this study, we evaluated neonates who underwent umbilical venous catheterization and developed hepatic complications. Furthermore, we aimed to define all of the possible lesions and to clarify the imaging findings of umbilical venous catheter–induced hepatic injury. Methods Two hundred forty‐four neonates who underwent umbilical venous catheterization between March 2013 and September 2015 in a single tertiary care referral center were included in this study. To determine whether they had any hepatic complications, all patients underwent abdominal grayscale and Doppler ultrasound examinations, and their clinical data were recorded. Results The frequency of liver‐related complications from umbilical venous catheterization was 33.6% (82 of 244). Air in the portal venous system was the most frequent complication (20.1% [49 of 244]). Left portal venous thrombosis was noted in 6.1% (15 of 244). Parenchymal lesions in the liver related to umbilical venous catheterization were seen in 7.4% of patients (18 of 244) as follows: single nodular echogenic lesions (4.1% [10 of 244]), branching small nodular echogenic lesions (2.1% [5 of 244]), and large irregular heterogeneous lesions with laceration and perihepatic fluid (1.2% [3 of 244]). There was no statistical significance for any type of complication according to the gestational age ( P > .05). Conclusions Hepatic complications due to umbilical venous catheters are not uncommon in the neonatal period. Ultrasound is the best imaging modality for confirming the diagnosis and for follow‐up.
