“…In addition, some reports have stated that sonographic findings of PVG vary over the course of 1 day and are recognized as transitional imaging findings. 16,32 Currently, ultrasound is usually used as point-of-care ultrasound for managing and evaluating pediatric patients, [33][34][35] and PVG can usually be easily detected by ultrasound. 17 Clinically, the management of patients with PVG was not changed based on the dynamic movement of the PVG; however, prediction of the timing of recovery from PVG is useful for physicians to start enteral nutrition to increase patient body weight, and for cardiac surgeons to plan the next surgical intervention.…”

Objectives To demonstrate the association between the dynamic movements of hyperechoic foci in portal venous gas (PVG) and patients'/sonographic outcomes after congenital heart disease or cardiac events. Methods Thirty‐one pediatric patients requiring management of congenital heart diseases or cardiac events who had PVG on ultrasound were included in this retrospective study. The patient outcome was prognosis: dead or alive. The sonographic outcome was recovery from PVG, measured as days from PVG detection to when it diminished on ultrasound. The following sonographic findings of hyperechoic foci in PVG were compared between patients: detection within the mesenteric vein, having to‐and‐fro movements within the intrahepatic portal vein, distribution (left segment or both left and right segments) and shape (line or punctate) in the liver, and detection within the portal and hepatic veins. Comparisons were made using Fisher's exact/Mann–Whitney U test. Results Four patients died without having recovered from PVG. A significant difference was observed in terms of the to‐and‐fro movement (with/without to‐and‐fro movement in dead vs. alive patients: 3/1 vs. 1/26, respectively; P = 0.003). Furthermore, a significant difference in sonographic outcomes was observed regarding patients with/without hyperechoic foci within the mesenteric vein (days with vs. without this finding: 2.0 ± 1.24(1–5) vs.1 ± 0(1), respectively; P = 0.011). Conclusions In our small limited cohort, when PVG was visualized on ultrasound, close evaluation of the dynamic movement of hyperechoic foci, especially their to‐and‐fro movement within the intrahepatic portal vein and detection of hyperechoic foci within the mesenteric vein, were useful in predicting patients' outcomes and the time to PVG diminishment.
