子宫内膜异位症对冻融胚胎移植的影响 [PDF]

open access: yes, 2019
目的探讨子宫内膜异位症(EMs)对冻融胚胎移植(FET)的影响。方法回顾性分析2015年1月至2017年12月EMs患者(A组,n=657)与盆腔输卵管因素不孕症患者(B组,n=3 271)解冻囊胚移植周期的临床和实验室指标。结果 A组患者年龄大于B组[(32.07±3.92)岁vs.(31.41±4.42)岁]、不孕年限大于B组[(5.05±2.86)年vs.(4.61±3.19)年],但差异无统计学意义(P>0.05)。两组内膜厚度[(9.97±1.81)mmvs.(9.69±1.75)mm ...

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

open access: yesUltrasound 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 ...

不同内膜准备方案在子宫内膜异位症患者冻融囊胚移植中的疗效观察 [PDF]

open access: yes, 2019
目的研究不同内膜准备方案对子宫内膜异位症(EMs)患者囊胚冻融移植(FET)妊娠结局的影响。方法回顾性分析EMs患者375个囊胚FET周期,按照子宫内膜准备方式分为:单纯人工周期组(HRT组,45个周期),促性腺激素释放激素激动剂降调节后人工周期组(GnRH-a+HRT组,121个周期)和自然周期组(NC组,209个周期)。比较3种内膜准备方案的囊胚FET妊娠结局。结果 3组EMs患者间年龄、不孕年限、基础抗苗勒管激素(AMH)和基础内分泌水平比较均无统计学差异(P>0.05 ...

N‐terminal pro B‐type natriuretic peptide as biomarker to predict pre‐eclampsia and maternal–fetal complications

open access: yesUltrasound in Obstetrics &Gynecology, Volume 65, Issue 4, Page 447-455, April 2025.
ABSTRACT Objective A soluble fms‐like tyrosine kinase‐1 (sFlt‐1)‐to‐placental growth factor (PlGF) ratio cut‐off of 38 is currently considered optimal for ruling out pre‐eclampsia (PE); however, implementation of this ratio in clinical practice is limited.

Clinical utility of ultrasonography in pediatric and adolescent gynecology: retrospective review of 1313 ultrasound examinations

open access: yesUltrasound in Obstetrics &Gynecology, Volume 65, Issue 2, Page 226-234, February 2025.
ABSTRACT Objectives Ultrasound is the first‐line imaging modality of the pelvis in the pediatric and adolescent gynecology (PAG) population. Ultrasound findings in pre‐ and postpubertal PAG patients differ from those in adults. Diagnostic models for adnexal pathology have not been validated in this cohort.

Prediction of pre‐eclampsia using maternal hemodynamic parameters at 12 + 0 to 15 + 6 weeks

open access: yesUltrasound in Obstetrics &Gynecology, Volume 65, Issue 2, Page 173-182, February 2025.
ABSTRACT Objectives To compare the maternal hemodynamic profile at 12 + 0 to 15 + 6 weeks' gestation in women who subsequently developed pre‐eclampsia (PE) and those who did not, and to assess the screening performance of maternal hemodynamic parameters for PE in combination with the Fetal Medicine Foundation (FMF) triple test, including maternal ...

Exploring pathophysiological insights to improve diagnostic utility of ultrasound markers for distinguishing placenta accreta spectrum from uterine‐scar dehiscence

open access: yesUltrasound in Obstetrics &Gynecology, Volume 65, Issue 1, Page 85-93, January 2025.
ABSTRACT Objective Accurate differentiation between placenta accreta spectrum (PAS) and uterine‐scar dehiscence with underlying non‐adherent placenta is often challenging, even for PAS experts, both prenatally and intraoperatively. We investigated the use of standardized two‐dimensional grayscale ultrasound and Doppler imaging markers in ...

Evaluating use of two‐step International Ovarian Tumor Analysis strategy to classify adnexal masses identified in pregnancy: pilot study

open access: yesUltrasound in Obstetrics &Gynecology, Volume 64, Issue 6, Page 808-817, December 2024.
ABSTRACT Objectives The primary aim was to validate the International Ovarian Tumor Analysis (IOTA) benign simple descriptors (BDs) followed by the Assessment of Different NEoplasias in the adneXa (ADNEX) model, if BDs cannot be applied, in a two‐step strategy to classify adnexal masses identified during pregnancy. The secondary aim was to describe the
