目的比较经阴道超声与腹部超声诊断异位妊娠的临床价值。方法 112例妇产科确诊为异位妊娠的患者为研究对象,均同时接受经阴道超声和腹部超声检查。比较经阴道超声和腹部超声诊断异位妊娠的准确性,分析二者超声图像特点及差异。结果异位妊娠最常见的部位是输卵管,其他常见部位有宫颈、宫角及卵巢;在超声图像上主要表现为无回声区内可见胚芽、卵黄囊及原始心管搏动。经阴道超声对于异位妊娠的诊断准确性为94.64%,高于腹部超声的76.79%,差异有统计学意义(P<0.05)。经阴道超声对于宫外混合性团块、宫外孕囊影及宫外孕囊中可见胎心及胎芽的检出率明显高于腹部超声(P<0.05),二者对于子宫直肠陷窝积液的检出率比较差异无统计学意义(P>0.05)。结论经阴道超声诊断异位妊娠患者的准确性明显优于腹部超声,值得在临床中推广应用。
Objective To compare the clinical value of transvaginal sonography and abdominal ultrasonography in the diagnosis of ectopic pregnancy. Methods A total of 112 patients with obstetrics and gynecology diagnosed as ectopic pregnancy were enrolled in this study. Transvaginal sonography and abdominal ultrasonography were performed simultaneously. The accuracy of transvaginal ultrasound and abdominal ultrasonography in diagnosing ectopic pregnancy was compared, and the characteristics and differences of the two ultrasound images were analyzed. Results The most common site of ectopic pregnancy was the fallopian tube. Other common sites were cervix, cornual angle and ovary. On the ultrasound image, there were germ, yolk sac and primitive cardiac pacing in the anechoic area. Transvaginal ultrasound for the diagnosis of ectopic pregnancy accuracy was 94.64%, higher than 76.79% of abdominal ultrasound, the difference was statistically significant (P <0.05). Transvaginal ultrasound for extrauterine mixed mass, ectopic gestational cysts and ectopic gestational sac visible fetal heart rate and fetal bud detection rate was significantly higher than the abdominal ultrasound (P <0.05), both for the detection of uterine rectal lacunar effusion The difference was not statistically significant (P> 0.05). Conclusion The accuracy of transvaginal sonography in diagnosing ectopic pregnancy is better than that of abdominal ultrasonography, which is worth popularizing in clinic.
