Effect of abnormal placental cord insertion on hemodynamic change of umbilical cord in a tertiary center: a prospective cohort study.
Postgrad Med J
January 2025
Department of Obstetrics and Gynecology, Chung Shan Hospital, No. 11, Ln. 112, Sec. 4, Ren'ai Rd., Da'an Dist., Taipei City 10689, Taiwan.
Background: Our study aims to evaluate the umbilical vein (UV) hemodynamic change in the prenatal cohort of pregnancies diagnosed with abnormal placental cord insertion (aPCI).
Methods: From January 2022 to December 2022, the fetal umbilical cord insertion site was sonographically examined in singleton fetuses, and umbilical cord blood flow was calculated. The umbilical artery and UV Doppler flow indexes were assessed in cases of normal and abnormal cord insertion.
Proximate cord insertion in monochorionic twins with selective fetal growth restriction.
Am J Obstet Gynecol MFM
January 2025
Division of Neonatology, Department of Pediatrics, Willem-Alexander Children's Hospital, Leiden University Medical Center, Leiden, The Netherlands.
Background: Monochorionic (MC) twins share a single placenta which can be unequally shared, leading to selective fetal growth restriction (sFGR). Limited data is available on the prevalence and clinical consequences of proximate cord insertion (PCI) in sFGR pregnancies.
Objective: We aimed to investigate the prevalence of PCI in MC placentas with and without sFGR and per type of sFGR, and study the placental characteristics and perinatal outcome of PCI in sFGR pregnancies.
Placental cord insertion migration: Implications for ultrasound documentation and follow-up of abnormal placental cord insertion site.
Australas J Ultrasound Med
November 2024
Discipline of Medical Radiation Science, Curtin Medical School Curtin University Perth Western Australia 6845 Australia.
Introduction/purpose: It is well-documented in the literature that the placenta migrates during pregnancy; however, studies regarding placental cord insertion (PCI) migration are scarce. This longitudinal, prospective study aimed to determine whether PCI migration is a true phenomenon, to assess whether the PCI can change classification during pregnancy and to determine the validity of PCI site documentation including follow-up of abnormal PCI.
Methods: Eighty-three participants who had first, second and third trimester ultrasound examinations at a Western Australian private imaging practice over a 12-month period between November 2021 and November 2022 were recruited.
Prenatal diagnosis of vasa praevia in routine clinical practice: Prevention of stillbirths and impact on perinatal outcomes.

Article Synopsis
- Vasa praevia (VP) is a serious condition where fetal blood vessels are near the cervix, and detecting it before birth can significantly improve baby survival rates.
- The study aimed to demonstrate a two-stage ultrasound screening process for identifying VP during routine prenatal care, which could help prevent stillbirths and perinatal deaths.
- Analyzing data from over 53,000 pregnancies, the study found that VP occurred in about 1 in 1,192 pregnancies, with specific factors like low-lying placenta and placenta previa being strong indicators of the condition.
