彩色多普勒超声对妊娠晚期瘢痕子宫破裂的评估研究

Study on the evaluation of color doppler ultrasound in uterine rupture in late pregnancy

目的：探讨彩色多普勒超声检查对瘢痕子宫晚期妊娠破裂或先兆破裂的诊断和预测价值。方法：收治有剖宫产史的孕妇231 例，自妊娠35～40 周连续检测子宫下段厚度及子宫下段瘢痕情况，经腔内超声与腹部超声联合检查，并与手术结局对照分析。结果：经阴道超声和腹部超声联合检查2 例子宫下段前壁肌层消失，剖宫产术中均诊断为子宫破裂。结论：超声监测瘢痕子宫妊娠晚期子宫下段前壁肌层厚度能预测子宫破裂及先兆破裂。

Objective:To explore the value of color doppler ultrasonography in the diagnosis and prediction of the rupture orthreatened rupture of uterine scar pregnancy.Methods:231 pregnant women with cesarean section history were selected.They werecontinuous measurement of the thickness of the uterus and uterine scar since pregnancy 35～40 weeks,and they were givenultrasound examination combined with abdominal ultrasound,then control with the surgical outcome.Results:2 cases withdisappearance of anterior wall of the lower uterine segment diagnosed by the transvaginal ultrasound and abdominal ultrasound,finally,both of the patients were diagnosed as uterine rupture by the cesarean section.Conclusion:Ultrasonic monitoring used in thelate stage of uterine scar pregnancy can be predict rupture of uterus and threatened rupture by the thickness of the anterior wall ofthe lower uterine segment.
