In order to determine the occurrence of antenatal complications in twin pregnancies, we examined the medical records of 939 consecutive twin gestations delivered at Women's Hospital, Los Angeles County/University of Southern California Medical Center between 1980-1985. The rates of occurrence of the eight most common antenatal complications were determined and compared with their incidence in singleton gestations. In addition, complication rates were related to zygosity, levels of antenatal care, and time of antenatal diagnosis. Twin gestations had an 83% incidence of antenatal complications, in contrast to a 32% incidence in singleton gestations. The increased complication rate was due to the disproportionate increase in three complications: preterm labor, pregnancy-induced hypertension, and fetal death. Other complications did not occur more frequently in twin gestations than in singleton gestations. Monozygotic gestations were more frequently complicated by fetal death, and dizygotic gestations by pregnancy-induced hypertension.
为了确定双胎妊娠产前并发症的发生率，我们查阅了1980年至1985年间在洛杉矶县妇女医院/南加州大学医学中心连续分娩的939例双胎妊娠的病历。确定了八种最常见产前并发症的发生率，并与单胎妊娠的发生率进行了比较。此外，并发症发生率还与合子性、产前护理水平和产前诊断时间有关。双胎妊娠的产前并发症发生率为83%，而单胎妊娠的发生率为32%。并发症发生率的增加是由于三种并发症的不成比例增加：早产、妊娠高血压和胎儿死亡。其他并发症在双胎妊娠中并不比单胎妊娠更频繁发生。单合子妊娠更常并发胎儿死亡，双合子妊娠更常并发妊娠高血压。
