Background: Twin pregnancies account for 2 to 4% of the total number of births. Twin pregnancies are associated with significantly higher morbidity and mortality than are singleton pregnancies. Among the twin pregnancies, Dichorionic pregnancies occur in 70% of the total twin pregnancies. Monochorionic twins are at higher risk twins for perinatal complications. The objective of the present study is to analyze neonatal outcomes associated with Monochorionic and Dichorionic twin pregnancies.

Material and Methods:

The study was Retrospective and Hospital based study conducted in Tertiary Care Hospital in Mumbai in 2018. The sample size was 50 (N=50). The patients with maternal co–morbidities like DM or other systemic illness were excluded from the study. The patients were divided into two groups, viz. Monochorionic or Dichorionic twins. The maternal age and its association with Monochorionic and Dichorionic twin pregnancy are studied. The neonatal outcome in Monochorionic and Dichorionic twins were then analyzed in terms of Birth weight, NICU stay, Neonatal deaths, etc.

Statistical analysis:

The maternal age and the various neonatal outcomes in Monochorionic and Dichorionic twin pregnancy were recorded. The student t test was used to compare the difference in both groups.


The maternal age was almost similar in both Monochorionic and Dichorionic twin pregnancies. The mean Birth Weight was more in Dichorionic group (p < 0.05). The Neonatal Outcomes like IUFD, TTTS and Discordant growth were more common in Monochorionic group as compared to Dichorionic group.

Conclusion and Recommendations: 

Twin pregnancy rates have increased in the past 25–30 years, particularly in developing countries. The reasons may be more advanced maternal age and increased use of assisted reproductive techniques. The neonatal mortality and morbidity in twin deliveries is high in Monochorionic pregnancy as compared to Dichorionic pregnancy. The early identification of chorionicity in early pregnancy is necessary to prevent neonatal complications.
