Objectives:

The objective of this study is to assess maternal and perinatal outcome of twin pregnancies with single fetal demise in terms of chorionicity and fetal death time.

Material and Methods:

All the deliveries between January 2008 and July 2015 were reviewed retrospectively and 85 twin pregnancies with single fetal demise were included. These cases were grouped according to chorionicity and fetal death time.

Results:

The incidence of single fetal demise was 4.7 %. The mean delivery week was higher in dichorionic group (34.16±4.65) than monochorionic group (31.1±3.83). The ratio of deliveries before 34th gestational week were 71.4% in monochorionics and 35% in dichorionics. Monochorionics had 13 times risk for having delivery before 37th gestational week and 4 times risk for having delivery before 34th gestational week compared to dichorionics. Furthermore, monochorionics had 7 times risk for having abruptio placenta compared to dichorionics. Newborn intensive care unit admission ratio was 61.3% in dichorionics and 85.7% in monochorionics. Also, monochorionics had 3.7 times risk for admission to newborn intensive care unit compared to dichorionics.

Conclusion:

We recommend follow up of twin pregnancies with single fetal demise in terms of premature birth regardless of chorionicity. Also, close monitoring is recommended for monochorionic twin pregnancies with single fetal demise in terms of premature birth before 34 weeks of gestation, abruptio placenta, the need for neonatal intensive care and RDS.
