近年来,超声诊断宫外孕的作用日趋加强,主要是对已孕妇女排除宫内妊娠。作为特异性诊断方法,不甚理想。Mahong 等描述80%宫外孕显示附件异常,但并非特异性,在其它情况甚至正常人也可出现,35例随后证实为宫外孕者仅5侧见有妊娠囊,超声所见结合激素试验将有助于诊断宫外孕,但对妊娠试验阳性超声检查宫腔空虚者,很难确定手术日期。一些作者倡导用“鉴别范围”(discri-minatory zone),但仅41%初诊病人 hCG 高于此范围。另外,完全流产后三周内 hCG 仍可阳性,也致诊断困难。本文研究为经阴道超声的较好图象 In recent years, the role of ultrasound in the diagnosis of ectopic pregnancy is increasingly strengthened, mainly pregnant women have been excluded intrauterine pregnancy.
