Portal vein thrombosis (PVT) in newborns is also uncommon and is often secondary to coagulation dysfunction, infection, or umbilical vein catheterization (2). We report a 23\u2010year\u2010old primiparous woman whose fetus was diagnosed with UVV at 24\u2009+\u20092\u2009weeks of gestation, with turbulent flow on ultrasound. Serial follow\u2010up ultrasounds at 28\u2009+\u20093, 31\u2009+\u20090, and 36\u2009+\u20090\u2009weeks of gestation showed progressive enlargement of the varix and persistent abnormal flow characteristics. Following cesarean delivery of a male infant, abdominal ultrasound on postnatal day 3 revealed portal vein and ductus venosus thrombosis. Laboratory findings suggested a transient hypercoagulable state, with concurrent infection and metabolic acidosis. Despite no obvious short\u2010term interval resolution of the thrombotic lesions after anticoagulation and supportive treatment, the infant improved clinically and was discharged on postnatal day 9. This case highlights the importance of serial prenatal ultrasound surveillance and early postnatal follow\u2010up, with particular attention to the risk of portal vein thrombosis when umbilical vein abnormalities are detected prenatally.<\/jats:p>","DOI":"10.1002\/jcu.70319","type":"journal-article","created":{"date-parts":[[2026,6,29]],"date-time":"2026-06-29T03:41:07Z","timestamp":1782704467000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Intra\u2010Abdominal
