少见部位异位妊娠超声漏误诊分析的临床价值

目的 分析少见部位异位妊娠病例的超声漏误诊原因,探讨其临床应用价值。 方法 回顾性分析2015年1月-2017年8月我院经手术病理证实的325例少见部位异位妊娠超声图像特征,漏误诊原因。结果 子宫瘢痕处妊娠占37.5%；输卵管间质部妊娠占37.2%,其中误诊4例,漏诊1例；子宫角妊娠占11.7%,误诊5例,漏诊1例；卵巢妊娠占7.4%；宫颈妊娠占1.8%,误诊2例；盆腔妊娠占1.5%,漏诊1例；残角子宫妊娠、腹腔妊娠及肌壁间妊娠各占0.9%,肌壁间妊娠误诊1例。 结论 充分掌握超声声像图特征、漏误诊原因,有望提高少见部位异位妊娠的检出率、降低漏误诊率。

The clinical value of Analysis of the reasons of misdiagnosis#$NBSby ultrasound of rare ectopic pregnancy

Objective To analyze the ultrasound imaging features and the reasons of misdiagnosisS of ectopic pregnancy occurred in rare location, and to explore the clinical value. Methods The ultrasound imaging features of 325 patients, who were diagnosed with rare ectopic pregnancy by surgical pathology from Jan.2015 to Aug.2017 year in our hospital, were analyzed in this study, and the reasons of misdiagnosis and missed diagnosis and the methods and skills of ultrasonic diagnosis were also discussed. Results The most common rare ectopic pregnancy was uterine scar pregnancy, which accounted to 37.5%; the second one was interstitial tubal pregnancy with an occurrence rate of 37.2%, and 4 cases of misdiagnosis, 1 cases of missed diagnosis in; ovarian pregnancy occurred in 7.4% of cases; cornual pregnancy occurred in 11.7% of cases with 5 cases misdiagnosed and 1 cases missed; cervical pregnancy occurred in 1.8% of cases with 2 cases misdiagnosed; pelvic pregnancy occurred in 1.5% of cases with 1 case missed; intramural pregnancy occurred in 0.9% of cases with 1 cases misdiagnosed ; the occurrence rates of rudimentary uterine horn pregnancy and abdominal pregnancy were 0.9% each. Conclusion The detection rate might be improved by fully understanding the ultrasonographic features
