摘　　要：目的分析总结输卵管间质部、宫角、卵巢、宫颈、腹腔妊娠的声像图特点。方法回顾经手术及病理证实为特殊类型异位妊娠的18例患者的声像图,并与手术结果对照。结果宫角妊娠患侧宫角增大,妊娠囊或包块与宫腔相通,周围有肌层环绕;输卵管间质部妊娠包块与一侧宫底相连,包块外侧肌层消失;卵巢妊娠包块未破裂时包块与卵巢相连,当发生流产或破裂后,与输卵管妊娠难以鉴别;宫颈妊娠时宫颈膨大并可见以实性为主的囊实性包块,宫颈内口关闭;腹腔妊娠包块可异位到腹腔内任何部位。结论掌握输卵管间质部、宫角、卵巢、宫颈、腹腔妊娠的声像图特点,可提高特殊类型异位妊娠的超声确诊率。Objective To analyze the sonographic features of interstitial pregnancy,angular,cervical,ovarian and abdominal pregnancy. Methods The sonography of 18 patients with rare ectopie pregancy confirmed by surgery and pathology were retrospectively analyzed. The results of sonography were compared with that of the pathology. Results When amphicytu｜a was implanted in the cornua uteri,in the sonography enlarged cornua uteri could be seen, gestation sac or inhomogeneous echoic mass was surrounded by uniform myometrium. The mass of interstitial pregnancy was connected with the bottom side of the uterus. The ouside part of uniform myometrium surrounded the mass could not be seen. Unruptured ovarian pregnancy had characteristic of ovarian tissue surrounded the gestation sac or inhomogeneous echoic mass,while ruptured ovarian pregnancy was difficult to diagnose. The sonographic feature of cervical pregnancy was that the shape of uterus was like gourd. The volume of cervix was enlarged, the inhomogeneous echoic areas could be seen in the cervix, and the internal os was closed. The mass of abdominal pregnancy could be at any position in the abdominal cavity. Conclusion The diagnostic efficacy of ultrasound can be improved by mastering the features of interstitial pregnancy, angular, cervical, ovarian and abdominal pregnancy.
