We reviewed 488 twin pregnancies that resulted in the birth of neonates weighing 1000 g or more. Complications were present in 56.7% of all pregnancies; most common were threat of premature labor (17.4%) and preeclampsia (14.5%). Perinatal mortality was 31.8 per thousand. Eighty percent of neonatal deaths in twin pregnancies involved newborns weighing less than 2000 g. Twin pregnancies are high risk pregnancies and benefit from early diagnosis, prevention and treatment of the threat of premature birth.
我们回顾了488例分娩出体重1000克及以上新生儿的双胎妊娠病例。所有妊娠中有56.7%出现了并发症；最常见的是早产风险（17.4%）和先兆子痫（14.5%）。围产期死亡率为千分之31.8。双胎妊娠中80%的新生儿死亡涉及体重不足2000克的新生儿。双胎妊娠属于高危妊娠，早期诊断、预防和治疗早产风险会使其受益。
