三维彩色多普勒超声在胎盘植入中的诊断分析

目的 探讨三维彩色多普勒超声对胎盘植入的诊断价值.方法 随机选取本院2013年8月至2015年4月期间收治的胎盘植入产妇35例作为观察组,所有患者均经由产后病理检查得到确诊;另选取同期我院妇产科收治的正常产妇50例作为对照组,两组孕产妇均接受三维彩色多普勒超声检查,对胎盘后间隙、胎盘内部回声、胎盘位置等进行观察,并对子宫肌层厚度进行测量,同时对两组产妇的宫壁肌层血流情况进行检查.结果 超声检查对于产前胎盘植入的诊断准确率为77.27％,对产后胎盘植入的诊断准确率为69.23％,总诊断准确率为74.29％;产前胎盘植入者在超声声像图中均可见胎盘前置,其中产前植入产妇其植入面积＜ 1/2比例明显低于产后植入者,差异具有统计学意义(P＜0.05).结论 三维彩色多普勒超声是一种有效的胎盘植入诊断方法,通过结合宫壁肌层血流参数与声像图中胎盘特征,可有效对胎盘植入进行早期筛查,有助于临床治疗的及早开展.

Diagnosis analysis of three dimensional color Doppler ultrasound in placenta implantation

Objective To investigate the diagnostic value of three-dimensional color Doppler ultrasound in placenta implantation.Methods 35 patients with placenta implantation in our hospital from August 2013 to April 2015 were selected as observation group,all patients were confirmed by pathological examination.50 normal pregnant women in department of gynaecology and obstetrics of our hospital during the same period were selected as control group.Both two groups underwent three-dimensional color Doppler ultrasound examination,observed posterior placenta space,placenta intemal echo,location of placenta,measured the thickness of uterine muscle layer,inspected blood flow of uterine wall muscle layer.Results The accuracy of ultrasound in the diagnosis of prenatal placenta implantation was 77.27％,the accuracy of ultrasound in the diagnosis of postpartum placenta implantation was 69.23％,the total diagnostic accuracy was 74.29％;placenta previa was seen in all patients with prenatal placenta implantation,the rate of implanted area ＜1/2 in patients with prenatal placenta implantation was significantly lower than that in patients with postpartum placenta implantation (P＜0.05).Conclusion Three dimensional color Doppler ultrasound is an effective method for the diagnosis of placenta implantation.The combination of blood flow parameters and characteristics of placenta is effective for early screening of placenta implantation.
