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 ...

SSFSE序列及FIESTA序列在胎盘植入的成像诊断中的价值
Zhongguo shiyan zhenduanxue, 2018 胎盘植入(PIA)是产妇产前或产后大出血、子宫穿孔、继发感染的重要原因,具有较高的患病率和死亡率,也是目前产后子宫紧急切除术最主要的原因[1]。磁共振成像(MRI)以超快速扫描技术、大视野、任意角度成像为其主要优势,可全面立体的多方位观察解剖结构,软组织分辨率高。多项研究结果显示MRI在怀疑患有胎盘植入患者的产前检查具有重要参考价值,但不同MRI成像序列对诊断PIA具有重要意义[2,3 ...
