轮状胎盘的三维超声诊断价值

Diagnostic Value of Three-dimensional Ultrasound in Rotiform Placenta

目的探讨三维超声在诊断轮状胎盘中的图像表现及应用价值。方法回顾分析35例经产后证实为轮状胎盘的三维超声图像,观察其位置、形态、厚度及突向羊膜腔的情况。结果三维超声能更好地显示轮状胎盘在宫腔内的状态,更直观地观察其与胎儿的关系,评估轮状胎盘的程度。结论超声检查是诊断轮状胎盘的首选检查方法,如果同时应用三维显示,能更直观地显示轮状胎盘,提高对轮状胎盘诊断的认识。

Objective To explore the image manifestation and application value of three-dimensional（3D） ultrasound in the diagnosis of rotiform placenta.Methods 3D ultrasound images of 35 cases with rotiform placenta which were confirmed after the delivery were retrospectively analyzed,and the position,shape,thickness and processes to amniotic cavity were observed.Results 3D ultrasound could better display rotiform placenta in the womb,more intuitively observe the relationship between the placenta and fetus,and evaluate the extent of rotiform placenta.Conclusions Ultrasound is the first choice for the diagnosis of rotiform placenta.If use 3D in the same time,rotiform placenta can be more intuitively displayed,and we can improve the understanding of rotiform placenta.
