The management of multiple pregnancy.

Area of Science:

• Maternal-fetal Medicine
• Obstetrics
• Perinatology

Background:

• Multiple pregnancies, particularly twin gestations, represent a significant obstetric challenge.
• Accurate determination of chorionicity is fundamental for appropriate management and monitoring.
• First-trimester screening for aneuploidy is recommended for all multiple pregnancies.

Purpose of the Study:

• To outline the essential management strategies for twin pregnancies.
• To emphasize the importance of regular ultrasound surveillance for early complication detection.
• To highlight maternal complications and delivery considerations in twin gestations.

Main Methods:

• Ultrasound monitoring, including nuchal translucency screening in the first trimester.
• Fortnightly scanning for monochorionic (MC) twins to detect twin-twin transfusion syndrome and intrauterine growth restriction (IUGR).
• Vigilant maternal complication surveillance.

Main Results:

• Chorionicity determination is critical for guiding management.
• Early detection of complications like twin-twin transfusion and IUGR is facilitated by regular ultrasounds.
• Maternal complications are frequent and require careful monitoring.
• While vaginal delivery may be planned, cesarean section is the majority outcome.

Conclusions:

• Effective management of twin pregnancies hinges on chorionicity assessment and diligent ultrasound surveillance.
• Timely referral to fetal medicine centers is essential for managing complex cases.
• Anticipating and preparing for potential maternal complications and high rates of cesarean delivery is paramount.
