[摘要] 目的：比较经腹部超声(TAS)与经阴道超声(TVS)在异位妊娠诊断中的价值，提高异位妊娠的早期诊断率。方法：对我院2005年6月～2009年6月收治的237例异位妊娠患者进行回顾性分析，比较两种超声检查方法的阳性确诊率。结果：237例中，91例经 TAS检查诊断异位妊娠74例，阳性确诊率为81.3%；80例经 TVS检查诊断异位妊娠75例，阳性确诊率为93.8%，66例经 TAS和 TVS联合诊断异位妊娠65例，阳性确诊率为98.5%。结论：TVS比TAS诊断异位妊娠更准确，两者联合应用能有效提高阳性确诊率。

[Abstract] Objective: To compare the value of transabdominal ultrasound (TAS) and transvaginal ultrasound (TVS) in the diagnosis of ectopic pregnancy and improve the early diagnosis of ectopic pregnancy. Methods: To analyze the clinical data of 237 cases of ectopic pregnancy in our hospital from June 2005 to June 2009 retrospectively, compared positive diagnosis rate of two ultrasound methods. Results: 91 cases were given TAS examination of which 74 cases diagnosed, the positive diagnosis rate was 81.3%; 80 cases were given TVS examination of which 75 cases diagnosed, the positive diagnosis rate was 93.8%, 66 cases were given TVS and TAS examination of which 65 cases diagnosed, the positive diagnosis rate was 98.5%. Conclusion: The diagnosis rate of ectopic pregnancy of TVS is more accurate than TAS, their combination can increase the positive diagnosis rate.

异位妊娠(ectopic pregnancy，EP)是指受精卵着床于子宫体腔以外部位的妊娠，包括输卵管妊娠、卵巢妊娠、腹腔妊娠、宫颈妊娠、残角子宫妊娠及剖宫产瘢痕处妊娠等[1]，是妇科急腹症中最常见的疾病之一。异位妊娠发病率占妊娠的0.5%～1.0%[2]，若不及时诊断治疗，破裂后可导致大出血，严重者危及生命。随着超声检查水平的提高，尤其是阴道超声，它有效地提高了异位妊娠的早期诊断率，为临床早期治疗争取了时间，目前已成为诊断异位妊娠最常用的检查方法之一[3]，为比较经腹部超声(transabdominal sonography，TAS)和经阴道超声(transvaginal sonography，TVS)在异位妊娠诊断中的价值，本文回顾分析了2005年6月～2009年6月在本院经TAS及经TVS 诊断的237例异位妊娠者的超声检查结果，现将结果报道如下：
1 资料与方法
1.1 一般资料
选取本院2005年6月～2009年6月收治异位妊娠患者237例，年龄21～37岁，平均26.5岁。其中197例临床表现主要为停经、下腹痛、阴道不规则流血、阴道流点滴样咖啡色血、尿 hCG(+)等，另40例临床症状不典型。按检查方法不同，237例中，经 TAS检查91例，经TVS检查80例，经TAS和TVS联合检查66例。
1.2 仪器和方法
应用彩色多普勒超声诊断仪。经TVS检查时探头频率5.5～8.0 MHz。80例患者检查前均排空膀胱，取截石位，将表面涂有耦合剂的避孕套套在探头上 ......
