Fetal Hepatomegaly: Causes and Associations.

Fetal hepatomegaly is associated with significant fetal morbidity and mortality. However, hepatomegaly might be overlooked when numerous other fetal anomalies are present, or it might not be noticed when it is an isolated entity. As the largest solid organ in the abdomen, the liver can be seen well with US or MRI, and the normal imaging characteristics are well described. The length of the fetal liver, which can be used to identify hepatomegaly, can be determined by measuring the liver from the diaphragm to the tip of the right lobe in the sagittal plane. Fetal hepatomegaly is seen with infection, transient abnormal myelopoiesis, liver storage and deposition diseases, some syndromes, large liver tumors, biliary atresia, and anemia. Some of these diagnoses are treatable during the fetal period. Attention to the associated findings and specific hepatic and nonhepatic imaging characteristics can help facilitate more accurate diagnoses and appropriate patient counseling.©RSNA, 2020.

Pediatric tracheostomy: timing of the first tube change.

OBJECTIVES: No consensus exists on appropriate timing for the first tracheostomy tube change. The purpose of this study is to evaluate the safety of early tracheostomy change in the pediatric population. METHODS: A case series of all children undergoing tracheostomy at a tertiary children's hospital between 2008-2013 was retrospectively reviewed. RESULTS: A total of 151 children undergoing tracheostomy were identified. The average age was 48.1±66 months and median age was 10 months. The initial tracheostomy tube change occurred on postoperative day 3 (POD 3) in 65 children (43.0%) safely without any complications. CONCLUSIONS: Early tracheostomy tube change was safely performed in a significant portion of this population. Routine tube change on POD 3 in many children could save resources by reducing the length of ICU and hospital stays.
