摘要

在带有潜在胎盘的简单、非粘连性子宫疤痕裂开和胎盘植入谱的严重末端之间进行准确的产前区分是有问题的,因为两者在产前成像中可能看起来相似。这可能导致胎盘植入谱的错误诊断,从而导致产科焦虑、过度治疗和潜在的医源性发病率。尽管病因可能相似,但这两种情况的表现和处理方式却截然不同。对7例已确诊的单纯性子宫瘢痕破裂伴前置胎盘的产前超声特征进行了检查。瘢痕破裂常见的声像图特征是子宫肌层变薄(

Absence of abnormal vascular changes on prenatal imaging aids in differentiating simple uterine scar dehiscence from placenta accreta spectrum: a case series.

Accurate prenatal discrimination between a simple, non-adherent uterine scar dehiscence with an underlying placenta and the severe end of the placenta accreta spectrum is problematic as the two can appear similar on prenatal imaging. This may lead to the false diagnosis of placenta accreta spectrum resulting obstetric anxiety, overtreatment and potential iatrogenic morbidity. Despite potential similarities in the etiology, the manifestation and management of these two conditions is very different. The prenatal sonographic features of seven confirmed cases of simple uterine scar dehiscence with an underlying placenta previa were examined. The common sonographic features found for scar dehiscence was a thinned myometrium (<1 mm) overlying a generally homogenous placenta and a placental bulge. There was absence of lacunae and features of hypervascularity including bridging vessels. Our findings suggest accurate discrimination between a simple scar dehiscence with the placenta underlying it and placenta accreta spectrum can be made on prenatal ultrasound if the placenta is carefully examined for the vascular features unique to PAS.
