Abstract
Ultrasound scanning is an imaging modality that continues to gain acceptance in pediatric and neonatal medicine.
Despite the early adoption in obstetrics and maternal-fetal medicine, the actual bedside implementation in neonatology has unfortunately been much slower. Examples in neonatology where ultrasound scanning may continue to expand include central line placement, endotracheal tube localization, cardiac function assessment, bowel viability assessment, necrotizing enterocolitis and many other measurement of the organs in newborns.
Ultrasound is the preferred initial imaging modality for evaluating the liver and biliary tract in children, especially newborns. Typical indications are hepatomegaly, jaundice, anomalous hepatic assessment, ascites, suspected liver abscess or liver mass.
Ultrasound gives information on the size and structure of the liver and demonstrates both localized lesions and diffuse diseases.
Doppler ultrasound is useful for locating vessels and for ensuring the permeability of the vascular structures. It is helpful for assessing the presence and direction of blood flow in the hepatic artery, hepatic veins and portal veins. Normal vascular flow patterns can be readily seen in children of all ages.
There are only few studies conducted as routine US scanning after the birth in unselected population of patients. In these retrieved studies, there were 3-5.9% abnormal scans seen in neonates. More than 95% were in kidneys, either as ectopic/pelvic kidney or severe ureteropelvic junction obstructions. Mostly were suspected in utero. Therefore, these results didn’t identify the need for routine US scanning of the retroperitoneal space. Also, there are conflicting reports on the optimal time to perform a postnatal abdominal scan for urological abnormalities after birth, ranging 48 to 72 hours after the birth, due to relative oliguria in the first 72 hours of life which may lead to wrong estimation of the degree of hydronephrosis.
Therefore, as take home message should be the recommendation that routine US of the abdomen in neonates during the early neonatal period is valuable for diagnosis and follow up of the progression of NEC, extensive vomiting, IVC and Ao measures and indices and UVC placement.
