Abstract

Twin pregnancies can be complicated. Early diagnosis with accurate dating, determination of chorionicity, screening for chromosomal and structural abnormalities, placental evaluation, and cervical length assessment should be completed in the first half of gestation. Routine fetal growth is recommended for all twins with serial surveillance for those complicated by anomalies, cervical shortening, growth disturbances, and amniotic fluid abnormalities. Twins with monochorionic placentation require heightened scrutiny for unequal placental sharing with discordant twin growth or selective intrauterine fetal growth restriction, twin-twin transfusion syndrome, twin anemia-polycythemia sequence, and single-fetal demise. Familiarity with essentials can assist practitioners involved in the management of twins.

摘要

双胎妊娠可能会很复杂。应在妊娠前半期完成早期诊断，包括准确确定孕周、判断绒毛膜性、筛查染色体和结构异常、评估胎盘以及测量宫颈长度。建议对所有双胎进行常规胎儿生长监测，对合并异常、宫颈缩短、生长受限和羊水异常的双胎进行连续监测。单绒毛膜双胎需要更密切的检查，以发现胎盘共享不均伴双胎生长不一致或选择性胎儿生长受限、双胎输血综合征、双胎贫血-红细胞增多序列以及单胎死亡。熟悉这些要点有助于参与双胎管理的从业者。
