OBG · Multiple pregnancy: monoamniotic twins

Sample item

What is the most serious complication of monoamniotic twin pregnancy and the usual management approach?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Cord entanglement, with elective caesarean delivery at about 32 to 34 weeks

Monoamniotic twins share one amniotic sac and are at high risk of cord entanglement and sudden intrauterine death. They need intensive surveillance and elective caesarean section at 32 to 34 weeks. Antenatal steroids are given before delivery.

Option by option

  • A. Fetal growth restriction only, with induction at 40 weeks

    Late induction would expose the twins to entanglement risk.

  • B. Cord entanglement, with elective caesarean delivery at about 32 to 34 weeks (correct)

    Correct. Cord entanglement drives the early delivery policy.

  • C. Placenta praevia, with vaginal delivery at term

    Placenta praevia is not specific to monoamniotic twins.

  • D. Cervical incompetence, with cerclage

    Cerclage is not the main concern.
