【摘要】 目的 应用腔内超声对异位妊娠导管环与宫内孕黄体囊肿的回声进行鉴别，以提高异位妊娠的早期检出率。方法 对比分析46例异位妊娠患者超声探及的导管环与同侧卵巢实质的回声；对照40例正常宫内孕的黄体囊肿与卵巢实质的回声。结果 46例异位妊娠中，40例(87%)导管环回声高于或等于卵巢实质；而40例宫内孕中，黄体囊肿周边回声高于卵巢实质的仅有2例(5%)，二者差异有非常显著性(P<0.01)。结论 异位妊娠导管环的回声通常比卵巢实质回声高，而黄体囊肿常常与卵巢实质呈等回声或低于卵巢实质回声。【关键词】 妊娠，异位；超声检查；卵巢；诊断，鉴别

【Abstract】 Objective The pupose of this report is to compare the echogenicity of the tube ring of an ectopic pregnancy with the corpus luteum cyst of the ovary for improving early detection of ectopic pregnancy.Methods In 46 patients with clinically suspected ectopic pregnancy and sonography found an adnexal tube ring,echogenicity of the ring was compared with the echogenicity of the ovarian parenchyma.Simultaneously,in 40 patients with intrauterine pregnancy,echogenicity of the corpus luteum cyst was compared with echogenicity of the ovarian parenchyma.Results 40 (87%) of the 46 tube rings had echogenicity equal to or greater than that of ovarian parenchyma.In 40 patients with intrauterine pregnancy,the corpus luteum cyst was more echogenic than ovary in only 2(5%) cases.Conclusion The tube ring of an ectopic pregnancy is usually more echogenic than ovarian parenchyma,and the corpus luteum cyst is usually equal to or less echogenic than the ovary. ......
