Perinatal Outcome of Twin Pregnancy and Influence of Chorionicity on it
Background: Monochorionic twin gestations are at increased risk of a variety of pregnancy complications which can be minimized by early antepartum diagnosis and management. This study is to assess the influence of chorionicity in twin pregnancies on perinatal outcome.
Materials and Methods: A prospective study was conducted at, Institute of maternal and child health Calicut over a period of one year; 2005 to 2006. The total of, 200 cases of twin pregnancies were followed up from antenatal period, upon their admission to ward and labour room.
Results: Among 200 twin pregnancies, 62% were dichorionic diamniotic twins, 37% were monochorionic diamniotic. Average gestational age of monochorionic twin was 35.7 and that of dichorionic twin was 36.5. Perinatal mortality of monochorionic twin was 180/1000 when compared to 60.5/1000 for dichorionic twin.
Conclusion: Perinatal mortality of monochorionic twin is definitely more when compared to dichorionic twin.
