Descrição

Abstract Conjoined twins (CTs) are a rare complication from monochorionic and monoamniotic twin pregnancies. We describe the use of 3D technologies, including 3D virtual and 3D physical models on prenatal evaluation of one parapagus CT. A 16-year-old G1P0 woman was referred for fetal magnetic resonance imaging (MRI) anatomical evaluation of a CT at 28 weeks of gestation. 3D images of the fetal surface were generated by the software during the examination for spatial comprehension of the relationship between the fetal parts. The pair of CTs died at the 32nd week of gestation, a few hours after cesarean section. 3D technologies are an important tool for parental counseling and preparation of the multidisciplinary care team for delivery and neonatal assistance and possible surgical planning for postnatal separation in CTs cases.
