Two separate but communicating endometrial cavities and a
single uterine cervix.

(Possibly underestimated)

Labour events- Apparently uneventful
Delivered- Vaginally
Two Male babies

(Confirmed by Labour Room USG)
18. Patient showed no evidence of labour
after this episode, even on prolonged
waiting
Os gradually got
reduced in size
Cervix started to
reform

Aim- To continue the F3 baby in the Right horn
as long as possible
Oxytocics withheld
Breast feeding discouraged
Both babies sent to NICU as LBW babies
Both babies expired within 7 days due to sepsis
Mother kept in close observation
Antenatal steroids administered
Weekly scanning to monitor fetal growth
21. Follow up conditions- Satisfactory
Follow up USG-
Involuting left horn
Normally growing fetus in right horn
Investigations-
Hb- 10.2 g/dl
PPBS- 102mg/dl
Rest of the days of hospital stay- Uneventful
22. On One Fine Morning
At GA 36 wk 3 days (09.10.2011)
She developed
PRETERM LABOUR
26. Delivered- Single Female baby

THIRTY SIX DAYS
The longest known intertwin delivery interval is 153 days
A case report of delayed delivery of 99 days in a triplet pregnancy was
also presented
Successful outcome
31. Raises a controversy regarding
an established concept
Normal contraction wave originates from uterine
pacemakers, located at uterine end of the fallopian tubes,
that spreads throughout the uterus, depolarizing the whole
organ *
