患者女,28岁,因“停经39天,尿人绒毛膜促性腺激素(+),阴道少量出血”就诊。患者平素月经规律。经腹超声检查:子宫前位,大小约6.2 cm×5.6 cm×5.8 cm,肌层回声均匀,子宫内膜厚约1.1 cm;双侧卵巢大小、形态、内部回声均未见异常,左侧输卵管走行区探及2个囊样回声,大小分别约1.0 cm×0.7 cm、0.8 cm×0.6 cm(图1A);嘱孕妇排尿后,采用高频探头探及左侧输卵管

患者女,28岁,因“停经39天,尿人绒毛膜促性腺激素(+),阴道少量出血”就诊。患者平素月经规律。经腹超声检查:子宫前位,大小约6.2 cm×5.6 cm×5.8 cm,肌层回声均匀,子宫内膜厚约1.1 cm;双侧卵巢大小、形态、内部回声均未见异常,左侧输卵管走行区探及2个囊样回声,大小分别约1.0 cm×0.7 cm、0.8 cm×0.6 cm(图1A);嘱孕妇排尿后,采用高频探头探及左侧输卵管内毗邻的妊娠囊回声,内探及卵黄囊(图1B)。

经阴道超声检查:左侧输卵管走行区探及2个相邻的妊娠囊,大小分别约1.0 cm×0.8 cm、0.8 cm×0.7 cm,卵黄囊直径分别约0.5 cm、0.4 cm;CDFI未见心管搏动(图1C)。超声诊断:左侧输卵管未破裂型妊娠(双绒毛膜双羊膜囊)。行腹腔镜下异位妊娠病灶切除术,术中证实为左侧输卵管壶腹部妊娠(图1D)。术后病理:输卵管内绒毛组织及滋养细胞。

讨论 
 
异位妊娠是妇产科常见的急腹症之一,其发生率占正常妊娠的1%,单侧输卵管双胎异位妊娠占异位妊娠的0.5%。近年来,随着辅助生育技术的开展、促排卵药物的应用,单侧输卵管双胎异位妊娠个案报道逐渐增多。该孕妇由于未接受DNA检测,故不能准确区分是单卵双胎还是异卵双胎;早孕期超声显示2个妊娠囊,仅提示单侧输卵管双胎异位妊娠(双绒双羊)。
 
在未使用促排卵药物和辅助生育技术的情况下自然受孕,发生单侧输卵管双胎异位妊娠的概率极低,但其风险较单胎异位妊娠大,一旦破裂则危及孕妇生命。因此,及时、准确诊断,并采取相应的临床治疗手段十分必要。随着腔镜技术在临床的应用,对未破裂型异位妊娠采取腹腔镜下微创治疗是首选。
