The sonographic findings in fetal triploidy syndrome include intrauterine growth retardation, hydrocephalus, oligohydramnios, and hydropic changes of the placenta. Ultrasonography can establish the diagnosis only when placental findings coexist with a fetus. Although the majority of triploid conceptions abort spontaneously in the first trimester, occasionally they will progress further, but rarely to term. Six cases are presented in which the diagnosis was suspected by early ultrasound examinations, including one case in which there was an unusually large trophoblastic cyst. Determination of the karyotype is important for the management of a pregnancy with a live fetus, and has implications for genetic counseling of subsequent pregnancies.
胎儿三倍体综合征的超声检查结果包括宫内生长迟缓、脑积水、羊水过少以及胎盘水肿改变。超声检查只有在胎盘表现与胎儿并存时才能确诊。尽管大多数三倍体妊娠在孕早期自然流产，但偶尔也会继续发展，不过足月分娩的情况很少见。本文报告6例通过早期超声检查怀疑诊断的病例，其中1例有一个异常大的滋养层囊肿。确定核型对于有存活胎儿的妊娠管理很重要，对后续妊娠的遗传咨询也有意义。
