Objective: Small‐for‐gestational‐age (SGA) neonates are at increased risk of perinatal mortality and morbidity. We aimed to investigate the performance of uterine artery pulsatility index (UtA‐PI) at 19–24 weeks' gestation to predict the delivery of a SGA neonate in a Chinese population. Methods: This was a retrospective cohort study using data obtained between January 2010 and June 2018. Doppler ultrasonography was performed at 19–24 weeks' gestation. SGA was defined as birth weight below the 10th centile according to the INTERGROWTH‐21st fetal growth standards. The performance of UtA‐PI to predict the delivery of a SGA neonate was assessed using receiver‐operating‐characteristics (ROC)‐curve analysis. Results: We included 6964 singleton pregnancies, of which 748 (11%) delivered a SGA neonate, including 115 (15%) women with preterm delivery. Increased UtA‐PI was associated with an elevated risk of SGA, both in neonates delivered at or after 37 weeks' gestation (term SGA) and those delivered before 37 weeks (preterm SGA). The areas under the ROC curve (AUCs) for UtA‐PI were 64.4% (95% CI, 61.5–67.3%) and 75.8% (95% CI, 69.3–82.3%) for term and preterm SGA, respectively. The performance of combined screening by maternal demographic/clinical characteristics and estimated fetal weight in the detection of term and preterm SGA was improved significantly by the addition of UtA‐PI, although the increase in AUC was modest (2.4% for term SGA and 4.9% for preterm SGA). Conclusions: This is the first Chinese study to evaluate the role of UtA‐PI at 19–24 weeks' gestation in the prediction of the delivery of a neonate with SGA. The addition of UtA‐PI to traditional risk factors improved the screening performance for SGA, and this improvement was greater in predicting preterm SGA compared with term SGA. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

The article focuses on the study that assesses the role of three-dimensional (3D) power Doppler in diagnosing placenta accreta and compares its performance with gray-scale and color Doppler ultrasonography. It cites that the study was performed to 170 pregnant women and found out that 39 patients at the time of delivery are positive of placenta accrete and its variants. The study concludes that 3D power Doppler can be useful as complementary technique for placenta accrete diagnosis.

The relationship of large and vascularized chorioangiomas to adverse pregnancy outcome is well recognized. We present a patient with a large placental tumor and signs of impending fetal cardiac failure. The angioarchitecture of the tumor depicted by three-dimensional (3D) power Doppler ultrasound enabled us to accurately diagnose a placental chorioangioma. During the follow-up period, quantitative flow data obtained using 3D power Doppler indicated altered hemodynamics in the tumor and concomitant improvement in the condition of the fetus, enabling us to manage the mother conservatively. Spontaneous delivery occurred at 38 weeks without any complications. This report demonstrates the potential value of 3D power Doppler in prenatal diagnosis and monitoring of pregnancies complicated by large, vascularized chorioangioma. [ABSTRACT FROM AUTHOR]

Cervical pregnancy is frequently associated with extensive hemorrhage which, in severe cases, may be stopped only by hysterectomy. We report a case of an anembryonic cervical pregnancy diagnosed at 10 weeks, and associated with a large arteriovenous malformation. The patient was conservatively managed with simple selective uterine artery embolization. After embolization, her vaginal bleeding ceased and the level of serum β-human chorionic gonadotropin decreased rapidly. No additional treatment was given. The patient's postoperative course was uneventful and the cervical mass had disappeared at the follow-up 4 months later. To the best of our knowledge, this is the first report of conservative management of cervical pregnancy simply by uterine artery embolization. The role of three-dimensional power Doppler ultrasonography in the assessment of cervical pregnancy and in monitoring the therapeutic response is discussed. [ABSTRACT FROM AUTHOR]
