Visualization of multiple gestations via sonography typically occurs during the first trimester. The timing of this detection depends on several factors, including the resolution of the ultrasound equipment and the skill of the sonographer. An early scan, performed around 6-8 weeks of gestation, is often able to identify multiple gestational sacs and, potentially, fetal heartbeats, confirming the presence of twins.
Early identification of twin pregnancies allows for proactive management of potential risks associated with multiple gestations. These risks include preterm labor, gestational diabetes, and preeclampsia. Furthermore, early detection enables appropriate planning for delivery and neonatal care, optimizing outcomes for both the mother and the infants. Historically, diagnosis relied on clinical signs and symptoms, leading to later confirmation and potentially less optimized care. The advent of ultrasound technology has revolutionized the management of such pregnancies.
