Previous studies have highlighted the importance of confirming the position of an umbilical venous catheter (UVC) tip by an ultrasound (US) examination. However, methods for preventing insertion into the portal circulation under US guidance have not yet been established. We report 15 cases in which a UVC was successfully passed through the ductus venosus by compressing the upper abdomen near the portal sinus of the liver to align the umbilical vein and ductus venosus under US guidance. The UVC was inserted into the correct position in 14 of the 15 neonates (93%) without complications.

: Doppler abnormalities in the ductus venosus (DV) during the first trimester can serve as an early marker for the detection of congenital heart defects (CHDs), but the feasibility of systematically assessing the DV remains underexplored. This study aimed to evaluate the feasibility of performing DV assessments during routine first-trimester ultrasound screenings. : A multicenter, prospective, and descriptive study was conducted, including singleton pregnancies undergoing routine ultrasound screening between 11 + 0 and 13 + 6 weeks of gestation.

Methods: This is a retrospective cohort study of cases of TTTS treated by FLPC. The primary outcome was dual survival 30 days after delivery.

Rationale: Umbilical artery thrombosis (UAT) is a rare complication that is strongly associated with adverse neonatal outcomes, and the diagnosis and selection of an appropriate delivery time for good neonatal outcomes is challenging. Here, we present a case of prenatal suspicion and ultrasound diagnosis of UAT: a case report with targeted Doppler evaluation and timely delivery.
Patient Concerns: A 35-year-old (gravida 6, para 1) with reduced fetal movement at 32 weeks gestation, Doppler ultrasound showed that for gestational age, the pulsatility index (PI), resistance index, and peak systolic velocity/end-diastolic velocity ratio of the umbilical artery (UA), PI of the left uterine artery, and PI of the middle cerebral artery were all <5th centile; the systolic/atrial wave ratio of the ductus venosus was 50th to 95th centile.

Purpose: To determine the magnitude of fetal growth restriction (FGR) using fetal Doppler integrated with antenatal ultrasound in third-trimester screened pregnant women at Agra in northern India.
Methods: Screened participants underwent routine third-trimester ultrasound assessments integrating fetal Doppler studies. Any one or more of mean uterine artery (UtA) or umbilical artery (UA) pulsatility index > 95th centile, middle cerebral artery (MCA) or cerebroplacental ratio (CPR) PI < 5th centile, absent or reversed end-diastolic velocity, or ductus venosus PI > 95th centile was considered abnormal Doppler studies.

Objective: To explore the micro blood flow characteristics of normal singleton pregnancy placenta in middle and late pregnancy based on microvascular flow (MV-Flow) imaging.
Methods: We conducted a retrospective cohort study. Clinical records and placental ultrasound images of 485 patients in mid to late pregnancy with normal fetal development who underwent MV-Flow microvascular imaging in The First Affiliated Hospital of Anhui Medical University from January 2023 to December 2023 were retrospectively analyzed.
