Mono-amniotic mono-chorionic pregnancies are
un-common among twin gestations. Further twin reversed arterial perfusion
(TRAP) sequence is extremely rare presentation. Acardiac
acephalic fetus resulting as a result of TRAP sequence has an estimated
incidence of 1 in 35,000 pregnancies. To the best of our knowledge, no such
case has been reported till date which presented as obstructed labour.
We are highlighting this case so as to alert
the managing team of obstetricians regarding this rare cause of obstructed
labour. Also to increase awareness regarding this presentation presenting in
advanced second stage of labour with fetal malpresentation.
Only diagnostic pointer in index case was
malformed fetal toes visible at introitus of mother in advanced second stage of
labour.
