Transvaginal three-dimensional (3-D) and color Doppler ultrasound were used to establish a first-trimester definitive diagnosis and classification of thoracoomphalopagus conjoined twins following two-dimensional (2-D) transabdominal and transvaginal scans that indicated twin gestation of uncertain classification. Color Doppler in combination with 3-D ultrasound can be a useful complement to 2-D ultrasound to confirm early diagnosis and determine the extent of organ sharing and definitive classification of conjoined twins.
经腹二维超声和经阴道二维超声检查提示双胎妊娠分类不明确后，采用经阴道三维（3-D）彩色多普勒超声对胸腹联体双胎进行孕早期确诊和分类。彩色多普勒联合三维超声可作为二维超声的有益补充，以确认早期诊断，并确定联体双胎的器官共享程度和明确分类。
