The prenatal care of twin gestations is primarily concerned with attempts at preventing premature labor and the management of obstetric difficulties. Little data are available prior to delivery, apart from Rh-isoimmunized twin gestations, concerning an individual fetus' well-being in a twin gestation. Ultrasonography has been concerned with the single gestation, and has not been used extensively in the care and evaluation of twin gestations, apart from early diagnosis of the condition. This report involves a twin gestation in which a significant repeated difference in the ultrasonographic fetal biparietal diameter measurements clearly identifies a normal fetus and a fetus with intrauterine growth retardation. The management of this patient could have been more aggressive with the present knowledge available and so resulted in better perinatal outcome.
双胎妊娠的产前护理主要关注预防早产的措施及产科困难的处理。除了Rh血型免疫的双胎妊娠外，在分娩前关于双胎妊娠中单个胎儿健康状况的数据很少。超声检查一直主要用于单胎妊娠，除了早期诊断外，尚未广泛用于双胎妊娠的护理和评估。本报告涉及一例双胎妊娠，其中超声检查测得的胎儿双顶径存在显著的反复差异，这清楚地识别出一个正常胎儿和一个宫内生长受限的胎儿。鉴于现有的知识，对该患者的处理本可以更积极一些，从而获得更好的围产期结局。
