Which of the following are positive indicators for breech vaginal delivery?
Frank breech, fetal weight 1.5 kg to 3.5 kg, gestational age more than 34 weeks
Frank breech, estimated fetal weight 1.5 to 3.5 kg and gestation beyond 34 weeks are the favourable criteria for planned vaginal breech delivery. A frank (extended) breech fits the pelvis best, so cord prolapse risk is lowest (about 0.5 percent, versus 5 to 10 percent for complete and 15 to 20 percent for footling). The weight window matters because a fetus above 3.5 kg risks after-coming head entrapment, while below 1.5 kg the head is disproportionately larger than the trunk, so the body delivers through an incompletely dilated cervix and the head is trapped.
Why the others are wrong: Fetal weight less than 1.5 kg is unfavourable for the head-to-trunk disproportion reason above. Weight more than 3.5 kg invites head entrapment and disproportion. Flexed (complete) breech rather than frank carries a much higher cord-prolapse rate, so it is not a positive indicator even with acceptable weight and gestation.
Key point: Safe planned vaginal breech equals frank breech, 1.5 to 3.5 kg, more than 34 weeks, flexed fetal head. Hyperextended head, footling presentation or previous caesarean mandate caesarean section.
