Transvaginal ultrasonography was performed in 1150 patients suspected of having an ectopic gestation. The criteria for transvaginal sonographic diagnosis of ectopic pregnancy were established by targeted scanning of the pelvic organs and spaces. Sonographic assessment of tubal pregnancy and its differential diagnosis were based on six criteria: (1) the presence or absence of gestational structures within the fallopian tube, (2) the presence or absence of amorphous material in a dilated fallopian tube, (3) the presence or absence of indirect signs of ectopic pregnancy within the pelvis, (4) the echogenicity of a suspected finding relative to the ovary, (5) the presence or absence of flow (of lacunar origin) within the suspected sonographic finding, and (6) the relationship of a suspected sonographic sign to an intentionally displaced ovary. The latter 3 criteria help differentiate between tubal gestation and a corpus luteum. We believe these diagnostic criteria should be applied when performing transvaginal sonographic scanning of patients suspected of having an ectopic gestation.
对1150例疑似异位妊娠的患者进行了经阴道超声检查。通过对盆腔器官和间隙进行靶向扫描，确立了经阴道超声诊断异位妊娠的标准。输卵管妊娠的超声评估及其鉴别诊断基于六个标准：（1）输卵管内有无妊娠结构；（2）扩张的输卵管内有无无定形物质；（3）盆腔内有无异位妊娠的间接征象；（4）疑似发现相对于卵巢的回声性；（5）疑似超声检查发现内有无（腔隙性来源的）血流；（6）疑似超声征象与故意移位的卵巢的关系。后三个标准有助于区分输卵管妊娠和黄体。我们认为，对疑似异位妊娠的患者进行经阴道超声扫描时应应用这些诊断标准。
