目的彩色多普勒超声在胎盘植入诊断中的应用。方法运用彩色多普勒超声对34例胎盘植入患者和50例胎盘正常的孕产妇进行检查,并经产后病理证实。超声观察的内容包括:胎盘位置、胎盘内部回声、胎盘后间隙、胎盘与子宫肌层界线,测量子宫肌层厚度,阴道超声观察胎盘实质内、胎盘后间隙及宫壁肌层血流情况。结果 34例胎盘植入患者中,产前23例,超声诊断20例,2例阳性经金标准证实为非胎盘植入,误诊2例,漏诊5例,产后11例,超声诊断9例,1例阳性经金标准证实为非胎盘植入,误诊1例,漏诊3例,超声诊断正确率为76.5%。34例患者均经产后病理证实。结论彩色多普勒超声对胎盘植入诊断率较高,是值得推广运用的有效诊断方法。
Application of color Doppler ultrasound in the diagnosis of placenta accreta. Methods 34 cases of placenta accreta and 50 cases of placental normal pregnant women were examined by color Doppler sonography and confirmed by postpartum pathology. The contents of placenta, placental echo, posterior placenta, placenta and myometrium were measured. The thickness of myometrium was measured. The intravaginal placenta, the posterior placenta, and the blood flow of the uterine myometrium were observed. Results Among the 34 cases of placenta accreta, 23 cases were prenatal and 20 cases were diagnosed by ultrasonography. Two cases were confirmed as non-placenta accreta by gold standard, including 2 cases misdiagnosed, 5 cases missed, 11 cases postnatal, 9 cases diagnosed by ultrasound, 1 Positive cases of gold confirmed by non-placenta accreta, misdiagnosis in 1 case, missed diagnosis in 3 cases, the correct rate of ultrasound diagnosis was 76.5%. 34 patients were confirmed by postpartum pathology. Conclusion Color Doppler ultrasound has a high diagnostic rate of placenta accreta and is an effective diagnostic method worthy of promotion and application.
