This is a case study of malformed conjoined twins in a spontaneous triplet pregnancy. A 20-year-old primigravida spontaneously delivered at 22 weeks gestation a normal 425-gram male newborn followed by a delivery of a 525 grams pygopagus conjoined male twins. One twin had omphalocele, missing ears, cleft palate and dysmorphic figures while the other had imperforated anus and dysmorphic figures. The Apgar scores were 2/0. The placenta was monochorionic/diamniotic with single umbilical artery supplying both conjoined twins. Conjoined twin in a triplet pregnancy may be diagnosed by ultrasound as early as the first trimester. Failure in diagnosis of the condition resulted in early delivery of three premature infants. All three infants died after delivery.
这是一例自然三胎妊娠中联体双胎畸形的病例研究。一名20岁初产妇在妊娠22周时自然分娩出一名体重425克的正常男婴,随后又分娩出一对体重525克的骶部联体男婴。其中一个胎儿有脐膨出、耳部缺失、腭裂和畸形面容,另一个有肛门闭锁和畸形面容。阿氏评分分别为2分/0分。胎盘为单绒毛膜/双羊膜,单脐动脉为联体双胎供血。联体双胎在三胎妊娠中最早可在孕早期通过超声诊断。未能诊断出这种情况导致三名早产儿早产。三名婴儿均在出生后死亡。
