【摘要】 目的探讨经阴道超声检查输卵管妊娠的诊断价值。方法对77例阴道超声检查并经手术与病理证实的输卵管妊娠声像图表现与超声诊断作回顾性分析。结果二维声像图主要表现为附件区包块与盆腔液性暗区。包块分为胚芽心搏型、妊娠囊型、不均匀混合包块型3种类型。根据有特征性的二维声像图表现,经阴道超声诊断破裂型、未破裂型、流产型的准确率分别为87.23%、100%、34.62%。若结合盆腔包块、积液间接征象与病史,上述临床分型的超声诊断符合率则分别为95.74%、100%、84.61%。总诊断符合率为92.21%。结论经阴道超声对输卵管妊娠破裂型和未破裂型具有较高的诊断准确性,流产型大多数缺乏特征性声像图表现,是影响超声诊断输卵管妊娠准确性的主要原因。更多还原

【Abstract】 Objective To evaluate the value of transvaginal ultrasound in the diagnosis of tubal pregnancy.Methods The retrospective analysis was made according to transvaginal ultrasound inspection on 77 patients and their sonographic appearance and ultrasonic diagnosis of tubal pregnancy proved by surgery and pathology.Results The two-dimensional sonogram mainly showed the adnexal masses and the liquid area opaca in the pelvic cavity.The masses were divided into three types:germ heart-beat type,gestational sac type,and uneven mixed mass type.According to distinctive two-dimensional sonographic appearance,the accuracy rates of transvaginal ultrasound in the diagnosis of rupture,nonrupture,and abortion tubal pregnancy were 87.23%,100%,and 34.62%,respectively.In combination with pelvic mass,indirect sign of effusion,and patient history,the accuracy rates of ultrasonic diagnosis in the above clinical classifications were 95.74%,100%,and 84.61%,respectively.The accuracy rate of the total ultrasonic diagnosis was 92.21%.Conclusions Transvaginal ultrasound has higher accuracy in the diagnosis of rupture and nonrupture tubal pregnancy,but it lacks distinctive sonographic appearance in the diagnosis of the majority of abortion tubal pregnancy,which is the main reason for affecting the accuracy of ultrasonic diagnosis of tubal pregnancy.更多还原
