Longitudinal maternal hemodynamics in high‐risk pregnancies with different subtypes of pre‐eclampsia

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 5, Page 623-634, May 2026.
ABSTRACT Objective To evaluate maternal cardiac adaptation during pregnancy by comparing longitudinal hemodynamic profiles between women identified as high risk for preterm pre‐eclampsia (PE) who subsequently developed preterm PE, term PE or remained unaffected, as well as low‐risk women.

Perinatal outcomes of twin pregnancies complicated by early twin‐to‐twin transfusion syndrome treated with fetoscopic laser surgery

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 4, Page 461-469, April 2026.
ABSTRACT Objective The aim of this study was to evaluate the perinatal outcomes of monochorionic diamniotic (MCDA) twin pregnancies complicated by early twin‐to‐twin transfusion syndrome (TTTS) treated with fetoscopic laser surgery (FLS), and to compare rates of fetal survival across Quintero stages.

Placental insufficiency markers to assess the risk of non‐chromosomal genetic conditions in early‐onset fetal growth restriction

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 4, Page 492-499, April 2026.
ABSTRACT Objectives To assess the value of placental insufficiency markers for estimating the risk of genetic anomalies in fetuses with isolated early‐onset fetal growth restriction (FGR), defined as an estimated fetal weight ≤ 3rd percentile diagnosed ≤ 28 + 6 weeks' gestation.

Multiple pregnancy with complete hydatidiform mole and coexisting normal fetus: systematic review and meta‐analysis of clinical outcomes from non‐randomized studies

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 3, Page 272-282, March 2026.
ABSTRACT Objective Complete hydatidiform mole and coexisting normal fetus (CHMCF) is a rare condition for which there is significant heterogeneity in diagnosis, counseling and management of complications. The objective of this study was to summarize the prevalence of clinical outcomes in reported cases of CHMCF.

Ultrasound features in early pregnancy for predicting abnormal karyotype in first‐trimester miscarriage

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 3, Page 376-384, March 2026.
ABSTRACT Objective To investigate whether combining abnormal morphological features observed on ultrasound in live pregnancies that ended in a first‐trimester miscarriage can predict an abnormal karyotype. Methods This retrospective observational cohort study was conducted at the early‐pregnancy assessment unit at University College London Hospital ...

Fetoscopic laser ablation vs standard management for Type‐II and Type‐III vasa previa

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 3, Page 320-328, March 2026.
ABSTRACT Objective The standard management (SM) for vasa previa (VP) includes antepartum inpatient admission at 28–32 weeks' gestation followed by Cesarean delivery at 34–37 weeks. Case reports and case series have reported on fetoscopic laser ablation (FLA) as an alternative management approach for Types‐II and ‐III VP.

Cost–benefit analysis of first‐trimester pre‐eclampsia screening: comparison of multivariable Gaussian algorithm with and without placental growth factor

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 2, Page 162-167, February 2026.
ABSTRACT Objective Pre‐eclampsia (PE) is a leading cause of maternal and neonatal morbidity and mortality worldwide. Early identification of high‐risk pregnancies in the first trimester allows preventive treatment with low‐dose aspirin. This study aimed to evaluate whether multivariable Gaussian algorithm‐based PE screening strategies, with and without

妊娠家兎卵胞卵の体外受精及び卵胞卵採取後の妊娠経過について [PDF]

open access: yes, 1992
妊娠家兎の卵胞(≧1.0mm)から卵胞卵を採取し、修正BO液で12時間培養した後、射出精子による体外受精を試みた所、成熱率、受精率、分割率、はそれぞれ93.1%(255/274)、39.2%(100/255)、28.2%(72/255)であった。合計41個の2-4細胞期の卵子を偽妊娠家兎4羽に移植した所、1羽に1個の着床部位が認められたが産仔は得られなかった。片側卵巣より卵胞を全て穿刺吸引した場合、妊娠13日目の家兎で胎児が部分吸収され、また妊娠19日目の家兎では胎児の部分吸収及び死産が認められたが ...

Undetected cases after implementation of first‐trimester anomaly scan in low‐risk population: insights from the IMITAS study

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 1, Page 27-33, January 2026.
ABSTRACT Objective To assess the effectiveness of the first‐trimester anomaly scan (FTAS) performed as part of a centrally steered national screening program in The Netherlands by investigating false‐negative cases with a fetal structural anomaly that was not detected at the FTAS.
