Perinatal outcome and management of single fetal death in twin pregnancy: A case series and review
Objective: To determine neonatal outcome of single fetal
death in twin pregnancy.
Methods: Retrospective study was performed on 30
cases of single fetal death in twin pregnancy during the
period from August 1971 to December 1997 at Kitasato
university hospital.
Results: The incidence of single fetal death in twin
pregnancy was 6.2? among total number of 481
twins. Prognosis of surviving infants was satisfactory
except in one case, with malformation in 10 cases
of dichorionic twins (total 242 sets). In contrast, neonatal
death occurred in 6 cases of 20 monochorionic
twins (total 239 sets), 4 of which were among 7
cases of twin-to-twin transfusion syndrome (TTTS).
Cerebral palsy occurred in 2 infants of monochorionic
twins. One case was diagnosed as periventricular leukomalacia
(PVL) within one week after birth, and
this was the case of delivery 1 day after one twin
fetal death.
Conclusion: Single fetal death itself occurs more often in
monochorionic twins. There seems to be a benign outcome
for the surviving dichorionic twins. On the other
hand, there may be a grave outcome, though infrequent,
for monochorionic twins when concomitant TTTS has
existed. It is very important to identify the chorionicity
by ultrasound examination in early pregnancy.
