Multiple gestations account for approximately 3% of all live births, but contribute to a disproportionate 15% of the overall perinatal mortality. Ultrasound evaluation of twin pregnancies serves an important role in surveillance, early detection, and invasive treatment of complications in twin pregnancies, including spontaneous abortion, abnormalities in placentation, preterm labor, growth restriction, congenital abnormalities, fetal demise, fetal mal-presentation, and twin-to-twin transfusion syndrome. A review of literature regarding the indications and use of ultrasound in twin pregnancy is presented.
多胎妊娠约占所有活产的3%，但在围产期总死亡率中所占比例却高达15%。超声评估双胎妊娠在双胎妊娠并发症的监测、早期发现及侵入性治疗中发挥着重要作用，这些并发症包括自然流产、胎盘异常、早产、生长受限、先天性异常、胎儿死亡、胎位异常及双胎输血综合征。本文对有关双胎妊娠超声检查的适应证及应用的文献进行了综述。
