Double uterus with a pregnancy in each half

Area of Science:

• Reproductive Medicine
• Maternal-Fetal Medicine
• Gynecology

Background:

• Uterus didelphys is a rare congenital anomaly where the uterus has two separate horns.
• Pregnancies in uterus didelphys can be complicated by preterm labor and other adverse outcomes.
• Bicornuate uterus is a related anomaly, but uterus didelphys involves complete duplication of the cervix and vagina.

Observation:

• A case of twin pregnancy was observed, with each fetus located in a separate horn of a uterus didelphys.
• Labor commenced, resulting in the term birth of one fetus from its respective uterine horn.
• Following the delivery of the first twin, temporary labor contractions were noted in the contralateral uterine horn.

Findings:

• The pregnancy involved a fetus in each horn of a uterus didelphys, a rare presentation.
• One fetus was delivered at term.
• The contralateral uterine horn exhibited transient contractions post-delivery of the first twin, resolving within two hours.

Implications:

• This case highlights the potential for functional activity in both uterine horns during labor in uterus didelphys.
• Understanding the dynamics of labor in uterus didelphys is crucial for effective maternal and fetal monitoring.
• Further research into the hormonal and mechanical factors influencing labor in didelphic uteri may improve management strategies for these rare pregnancies.
