胎盘植入的超声诊断

目的探讨彩色多普勒超声对胎盘植入的产前,产后诊断。方法回顾性分析经手术证实的15例胎盘植入的二维声像图及彩色多普勒血流显像特点,从子宫肌壁厚度,胎盘内回声,胎盘后方与子宫肌壁间回声,CDFI观察胎盘实质内及胎盘后方血流做综合分析。结果 15例胎盘植入,1例经产前确诊,8例经产后确诊,5例为术中医生发现。胎盘植入产前诊断漏诊多。产前表现胎盘增厚,胎盘内血池异常丰富。胎盘下子宫肌层菲薄,胎盘下后间隙消失。彩超显示胎盘漩涡近子宫肌层处血流丰富,宫旁血管扩张。结论二维声像图结合彩色血流可以提高胎盘植入的产前诊断。

Ultrasound diagnosis of placenta accreta

Objective Explore color Doppler ultrasound prenatal and postnatal diagnosis of placenta accreta.Methods Retrospective analysis of 15 cases confirmed by surgery placenta implanted two-dimensional sonographic and color Doppler flow imaging characteristics of the echo from the uterine muscle wall thickness,placenta,placenta rear uterine intramural echo,CDFI observed the rear of the placental parenchyma and placenta blood flow to do a comprehensive analysis.Results 15 cases of placenta accreta patients with prenatal diagnosis,eight cases of post-natal diagnosis,and five cases of surgery,doctors found.Placenta accreta prenatal diagnosis missed.Prenatal placental thickening,abnormal blood pool in the placenta.Placental myometrium is meager,the placenta after the gap disappears.Color Doppler display the placenta whirlpool near the myometrium,the blood flow,parametrial blood vessels to dilate.Conclusion Two-dimensional sonographic combination of color flow can improve the prenatal diagnosis of placenta accreta
