Routine 36‐week scan: prediction of small‐for‐gestational‐age neonate
Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 1, Page 20-29, January 2025.ABSTRACT Objectives First, to compare the predictive performance of routine ultrasonographic estimated fetal weight (EFW) at 31 + 0 to 33 + 6 and 35 + 0 to 36 + 6 weeks' gestation for delivery of a small‐for‐gestational‐age (SGA) neonate. Second, to compare the predictive performance of EFW at 36 weeks' gestation for SGA vs fetal growth restriction ...

Zhongguo shiyan zhenduanxue, 2014 目前而言,异位妊娠发病率有升高趋势。异位妊娠需要及早诊断及早处理,改善患者预后。所以及时准确诊断是正确治疗的前提。虽然异位妊娠的诊断并不困难,可根据患者病史、体格检查、B超等仪器而确诊,但早孕5周前,B超并不能观察出胎心芽。为了探讨异位妊娠及早孕准确诊断,本文测定血清-HCG及孕酮值水平 ...

Zhongshan Daxue xuebao. Yixue kexue ban, 2023 目的探讨手术治疗的不同孕周的妊娠期附件扭转的临床特点和妊娠结局。方法回顾性分析2013年3月至2023年3月在中山大学附属第一医院住院手术治疗并分娩的39例妊娠期附件扭转患者的临床资料，其中妊娠早期（<14周）18例，妊娠中期（14~27+6周）11例，和妊娠晚期（≥28周）10例，比较3组的临床特点、诊治和妊娠结局的差异。结果妊娠早期组辅助生殖技术受孕的比例高于妊娠中、晚期组（P=0.026）。3组患者腹痛、恶心、呕吐、发热等临床表现差异无统计学意义，但妊娠中、晚期组患者白细胞升高更常见。妊娠早、

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]
, 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 ...

Ultrasound in Obstetrics &Gynecology, Volume 64, Issue 6, Page 768-775, December 2024.Abstract Objective Lower urinary tract obstruction (LUTO) is a chronic condition with a spectrum of outcomes. It is usually suspected prenatally based on ultrasound features (USFs). Given the unknown postnatal trajectory and the potential for significant morbidity and mortality, many families choose termination of pregnancy (TOP), often based on USFs ...

Ultrasound in Obstetrics &Gynecology, Volume 64, Issue 4, Page 470-479, October 2024.ABSTRACT Objectives Our aim was to examine the prenatal profiles of pregnancies affected by an atypical chromosomal aberration, focusing on pathogenic copy‐number variants (pCNVs). We also wanted to quantify the performance of combined first‐trimester screening (cFTS) and a second‐trimester anomaly scan in detecting these aberrations. Finally, we aimed
