Ultrasound 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 ...

Zhongguo shiyan zhenduanxue, 2016 胎盘植入是一种异常的胎盘附着形式,是导致产妇产后大出血的主要原因之一。近年来,随着剖宫产率的增高,胎盘植入（placenta accrete）的发生率也逐渐升高。广义的胎盘植入根据胎盘绒毛侵入子宫肌层深度分为3类:粘连性胎盘植入（placenta accrete vera）、植入性胎盘植入（placenta increta）、穿透性胎盘植入（placenta perccreta）[1 ...

Zhongguo shiyan zhenduanxue, 2016 胎盘植入是指胎盘蜕膜发育不良导致胎盘绒毛组织侵入子宫肌层,严重者侵及浆膜层,甚至可能涉及相邻盆腔器官[1]。胎盘植入是孕产妇围产期大出血及产后子宫切除不可忽视的原因,是孕产妇发病和死亡的一个重要因素。胎盘植入患病率日趋上升,可能与高龄孕妇比例增加,及以往流产和/或剖宫产史有关[2]。准确及时地诊断为临床手术方案的制定提供了重要依据。以往胎盘相关疾病影像学诊断多依靠超声检查 ...

孕中期甲胎蛋白和游离β人绒毛促性腺激素及脐动脉血流变化与不良妊娠结局的关系 [PDF]
, 2010 【目的】 探讨孕中期母血清标志物及脐动脉血流用于预测不良妊娠结局的临床价值?【方法】 采用时间分辨荧光分析技术,对876例孕14 ~ 21周的孕妇进行孕中期甲胎蛋白(AFP)?游离β人绒毛促性腺激素(free-β-hCG)检测;对其中536例孕妇在孕14 ~ 28周使用超声多普勒检测其脐动脉血流,并追踪其妊娠结局?用卡方检验比较孕妇血清标志物升高者(342例)?脐动脉血流异常者(82例)?血清标志物升高且脐动脉异常者(40例)之间不良妊娠结局的发生率的差别?【结果 ...
