Structural Anomalies in Multifetal Gestations

Area of Science:

• Reproductive Medicine
• Maternal-Fetal Medicine
• Prenatal Diagnosis

Background:

• Multifetal gestations, particularly twins, exhibit a higher incidence of structural anomalies compared to singleton pregnancies.
• Chorionicity determination is crucial, as monochorionic pregnancies face the greatest risk.
• Fetal anomalies in multifetal gestations necessitate complex counseling that addresses the entire pregnancy, unlike singleton cases.

Approach:

• Reviewing the incidence of structural anomalies in twin gestations.
• Highlighting unique considerations in managing multifetal anomalies, such as selective termination for discordant conditions.
• Emphasizing the importance of shared decision-making between healthcare providers and patients.

Key Points:

• Twin pregnancies have an increased risk of structural anomalies.
• Monochorionic twins face the highest risk.
• Counseling for multifetal anomalies requires a comprehensive approach, including options like selective termination.
• Shared decision-making is vital for optimal patient care.

Conclusions:

• Managing fetal anomalies in multifetal gestations demands specialized counseling strategies.
• Selective termination is a key consideration for discordant anomalies in twins.
• Provider-patient collaboration through shared decision-making enhances management of complex multifetal pregnancies.
