本文对可疑宫外孕患者２６例行阴道超声检查，发现未破损的输卵管妊娠１３例，其超声特征为附件区有约２ｃｍ环状中等回声包块，中心部呈液性无回声，依形态称“炸面圈”征，盆腔无积液。余１３例为早期输卵管妊娠流产型，包块小于５ｃｍ，积液少于２．５ｃｍ。经检验血β－ＨＣＧ确认妊娠，宫腔镜检查除外宫内妊娠。按输卵管妊娠经宫腔镜行输卵管插管５－氟脲嘧啶保守治疗。未破损型输卵管妊娠平均８．１±１．６天妊娠试验转阴，９±１．２天包块全部吸收。余１３例输卵管妊娠流产型平均１４．３±２．０天血β－ＨＣＧ转阴，平均４８±４．５天包块消失。２６例早期输卵管妊娠阴道超声诊断符合率为１００％。本研究提示：阴道超声对早期诊断输卵管妊娠有很重要的价值。对不典型病例，阴道超声结合血β－ＨＣＧ测定和宫腔镜检查是诊断早期输卵管妊娠的有效方法。
In this paper, 26 cases of suspected ectopic pregnancy vaginal ultrasound examination and found that 13 cases of unruptured tubal pregnancy, the ultrasound features of the attachment area is about 2cm annular echogenic mass, the center was liquid no echo, according to the form called “fried Donut ”sign, pelvic fluid. The remaining 13 cases of early tubal pregnancy induced abortion type, mass less than 5cm, effusion less than 2.5cm. After testing blood β-HCG confirmed pregnancy, hysteroscopy except intrauterine pregnancy. Tubal pregnancy by hysteroscopy tubal intubation 5-fluorouracil conservative treatment. Unimpaired tubal pregnancy averaged 8.1 ± 1.6 days Pregnancy test turned negative and all 9 ± 1.2 days mass was absorbed. The remaining 13 cases of tubal pregnancy induced abortion type averaged 14.3 ± 2.0 days of blood β-HCG negative, an average of 48 ± 4.5 days mass disappeared. The coincidence rate of vaginal ultrasound in 26 cases of early tubal pregnancy was 100%. This study suggests that: vaginal ultrasound for the early diagnosis of tubal pregnancy has a very important value. For atypical cases, vaginal ultrasound combined with blood β-HCG determination and hysteroscopy is an effective diagnosis of early tubal pregnancy.
