Management of the breech second twin

Area of Science:

• Obstetrics and Gynecology
• Perinatal Medicine

Background:

• Vaginal delivery of breech infants carries documented risks, leading to high cesarean section rates.
• Twin gestations present unique delivery challenges, particularly concerning fetal presentation.

Purpose of the Study:

• To evaluate cesarean section rates and perinatal outcomes for breech first and second twins compared to vertex presentations.
• To determine if current cesarean section indications are appropriate for breech second twins.

Main Methods:

• Retrospective analysis of twin deliveries between 1970 and 1977.
• Comparison of cesarean section rates and perinatal outcomes (mortality, Apgar scores) based on the presentation of the first and second twin.

Main Results:

• Breech first twins had significantly higher cesarean section rates than vertex first twins.
• Breech second twins did not show a significantly higher cesarean section rate than vertex second twins.
• No significant differences in perinatal mortality or Apgar scores were observed between breech first and second twins; cesarean sections improved outcomes equally for both.

Conclusions:

• Breech presentation, regardless of twin order, is associated with poorer outcomes compared to vertex presentation.
• Cesarean section management should be consistent for both first and second twins presenting as breech.
• Determining the presentation of the second twin is crucial for appropriate labor management decisions.
