Multiple Gestations

Tuesday, April 9, 2024

2:00pm – 3:30pm

Location:Governor's D - 4th Floor

CE: 1.5

This series of presentations will focus on critical aspects of prenatal ultrasound diagnostics. The first talk will emphasize the importance of measuring the crown-rump length (CRL) to establish an accurate estimated due date (EDD) and will explore sonographic techniques for pregnancy dating in both singleton and multiple pregnancies. It will also cover how to identify a failed pregnancy in the first trimester and detail the assessment of chorionicity in twins.

The subsequent discussion will delve into the use of ultrasound and Doppler imaging in identifying and managing complications unique to multiple gestations, such as twin-twin transfusion syndrome, twin anemia polycythemia sequence (TAPS), and acardiac twinning. Finally, attendees will learn about common fetal interventions in monochorionic twin pregnancies, with a clear explanation of the associated risks and benefits of each procedure.

Learning Objectives:

Discuss first-trimester biometric parameters for pregnancy dating, recognize the sonographic characteristics of twin-twin transfusion syndrome, and learn about the different fetal interventions that are available to treat different complications seen in monochorionic twins.
Describe how to confidently diagnose chorionicity, recognize the important role of Doppler for diagnosing Twin anemia polycythemia sequence (TAPS) and distinguishing this complication from twin-twin transfusion syndrome, and understand how these fetal interventions are performed from a technical perspective, acknowledging risks and benefits.
Discuss methods of pregnancy dating in twin gestations; understand the important role of Doppler in diagnosing acardiac twinning; and Identify by ultrasound at diagnosis markers of severity, poor prognosis, and technical challenges.
