TWINS take #2 Flashcards
Demise of Co-Twin is what
one of the twin dies in the sac
once the twin dies, most of the dead twin tends to be absorbed leaving behind a small flattened remnant known as the
fetus papyraceus
In some cases, only one fetus may be identified on ultrasound of a previously documented twin pregnancy, and this may be due to resorption or miscarriage of the demised twin, the so called
vanishing twin syndrome
what is twin embolization syndrome
the surviving healthy fetus affected by a monochorionic co-twin demise
what can occur if vanishing twin occurs in 2/3rd trimester
Premature labour
Infection due to the death of the fetus
Hemorrhage
At the end of the pregnancy, a low-lying fetus papyraceus may block the cervix and require acesareanto deliver the living twin.
