The aim of this study was to evaluate the value of endovaginal color Doppler ultrasonography in the early diagnosis of ectopic pregnancy in women after in vitro fertilization and embryo transfer, and to correlate the sonographic findings with ss-hCG serum levels. Thirty-five patients had proven ectopic pregnancies and 4 other patients had heterotopic pregnancies. The diagnosis was disclosed correctly in all cases by endovaginal color Doppler US by identifying an adnexal mass with placental flow and a nongravid uterus called a "cold uterus". An intrauterine sac with "double ring sign" was found in all normal intrauterine pregnancies when the hCG levels exceeded 1000 IU/l but in none of the patients with ectopic pregnancy (EP). These findings suggest the efficacy of the discriminatory hCG serum level of 1000 IU/l in the investigation of EP. In conclusion, this study describes the diagnostic importance of transvaginal color Doppler US in correlation with hCG serum levels in the early detection of EP avoiding life-threatening complications and improving patient outcome.
本研究的目的是评估经阴道彩色多普勒超声在体外受精和胚胎移植后女性异位妊娠早期诊断中的价值，并将超声检查结果与血清β-hCG水平相关联。35例患者确诊为异位妊娠，另有4例患者为异位妊娠。经阴道彩色多普勒超声通过识别具有胎盘血流的附件包块和称为“冷子宫”的非妊娠子宫，在所有病例中均正确诊断。当hCG水平超过1000 IU/l时，所有正常宫内妊娠均发现有“双环征”的宫内囊，但异位妊娠（EP）患者均未发现。这些发现表明，1000 IU/l的鉴别性hCG血清水平在EP检查中具有有效性。总之，本研究描述了经阴道彩色多普勒超声与hCG血清水平相关联在早期检测EP中的诊断重要性，可避免危及生命的并发症并改善患者预后。
