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

Ultrasound 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

Effect of aspirin on maternal hemodynamics in Chinese women at high risk for preterm pre‐eclampsia: longitudinal study

Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 5, Page 621-630, November 2025.
ABSTRACT Objectives To compare the maternal hemodynamics of Chinese women at low and at high risk for preterm pre‐eclampsia (PE) and assess the differences in hemodynamic parameters between high‐risk women with or without prophylactic aspirin. Methods This was a prospective longitudinal case–control study of 857 Chinese women with a singleton pregnancy

Role of aspirin therapy in modulating uterine artery resistance and placental growth between first and second trimesters of pregnancy

Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 5, Page 641-648, November 2025.
ABSTRACT Objective To evaluate the impact of low‐dose aspirin (LDA) on placental size and uterine artery pulsatility index (UtA‐PI) by analyzing longitudinal changes between the first and second trimesters in pregnancies at high risk for early‐onset pre‐eclampsia (PE).

Comparison of open fetal, fetoscopic and postnatal surgical repair for open spina bifida: decision analysis

Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 4, Page 433-442, October 2025.
ABSTRACT Objective Currently, there are several surgical approaches to manage fetal open spina bifida (OSB), namely postnatal surgical repair, open fetal surgery and its minimally invasive alternative, fetoscopic repair. Our objective was to determine the optimal surgical approach for OSB, weighing the benefits and risks to the fetus and the pregnant ...

Benefits and complications of fetal and postnatal surgery for open spina bifida: systematic review and proportional meta‐analysis

Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 2, Page 135-146, August 2025.
ABSTRACT Objective To derive pooled estimates of maternal, fetal and pediatric outcomes up to the age of 30 months in patients undergoing pre‐ or postnatal surgery for open spina bifida (OSB). Methods A systematic search was conducted in MEDLINE, PubMed (non‐MEDLINE records), Embase, Web of Science, ClinicalTrials.gov, Cochrane Central Register of ...

Placental biomarker and fetoplacental Doppler abnormalities are strongly associated with placental pathology in pregnancies with small‐for‐gestational‐age fetus: prospective study

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 6, Page 749-760, June 2025.
ABSTRACT Objective Placental dysfunction can result in small‐for‐gestational age (SGA) or fetal growth restriction (FGR). The aim of this prospective cohort study was to assess the association of the cerebroplacental ratio (CPR) and other more conventional fetoplacental Doppler indices, circulating placental growth factor (PlGF) levels and soluble fms ...

Automated multivolume placental reconstruction using three‐dimensional power Doppler ultrasound and infrared camera tracking

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 5, Page 624-632, May 2025.
ABSTRACT Objectives Placental insufficiency contributes to many obstetric pathologies, but there is no bedside clinical tool to evaluate placental perfusion. We have developed a method to acquire multiple three‐dimensional (3D) power Doppler (PD) ultrasound (US) volumes of placental vasculature, with infrared camera tracking of the precise spatial ...

Screening for pre‐eclampsia using pregnancy‐associated plasma protein‐A or placental growth factor measurements in blood samples collected at 8–14 weeks' gestation

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 5, Page 567-574, May 2025.
ABSTRACT Objectives To assess the value of pregnancy‐associated plasma protein‐A (PAPP‐A) in screening for preterm pre‐eclampsia (PE) (delivery < 37 weeks' gestation) measured in maternal blood samples collected before 11 weeks, and to compare the screening performance of PAPP‐A with that of placental growth factor (PlGF) from blood samples collected ...

403例前置胎盘的分析 [PDF]

, 1980
前置胎盘是妊娠晚期的严重合并症,处理不当,常可增加母婴死亡。近几十年来由于输血、抗菌素等方面的改进,母亲死亡率明显降低,但婴儿死亡率仍相当高,故仍是产科重要问题之一。 临床资料分析 发病率自1964年1月至1977年12月,共收治妊娠28周的前置胎盘403例(其中1969年和1970年因统计不全未列入统计),同时期分娩总数为25,600人,发病率为1.57 ...
