title: A systematic approach to first-trimester ultrasound assessment of twins.
abstract: The incidence of twin pregnancies has increased for the last 20 years mainly as a result of assisted reproduction technologies and pregnancies occurring in older women. Both maternal and perinatal mortality and morbidity are increased in twin pregnancies when compared with singletons. A systematic and detailed first-trimester ultrasound can be a useful tool for detecting chorionicity, growth discordance, and congenital malformations. Prediction of complications at an early stage can help with directing future management and counseling of patients.
