The authors recommended that dichorionic
pregnancies be delivered at 37 weeks and that the evidence for delivery of monochorionic twins prior to 36 weeks is lacking.
Regarding the neonatal morbidity including respiratory morbidities, necrotising enterocolitis and sepsis were seen to be reduced beyond 35 weeks of gestation in both monochorionic and dichorionic
groups, respectively (Table-3).
In the other 25% of monozygotic twins, the egg splits quickly, within 3 days, yielding two separate units and creating dichorionic
twins, each with their own placenta.
12) Classification regarding to chorionicity in our study showed a mean BW of 2055 g for dichorionic
pregnancies and 1799 g for monochorionic pregnancies.
We perform routine ultrasound evaluations every 3 weeks for our monochorionic twins and every 4 weeks for our dichorionic
twins, in the absence of any abnormalities.

Diamniotic Twins and Review of the Literature.
Perinatal outcome was poor in monochorionic twins as compared to dichorionic
Monochorionic twins had significantly high rates of stillbirths than dichorionic
(p = 0.
We must distinguish between monochorionic and dichorionic
9% patients had diamniotic dichorionic
twins while 16.
In both groups, more than 80% of pregnancies were dichorionic
, and elective cesarean delivery was performed in approximately one-third of women.
