Preterm labor

Low birth weight

High rate of fetal respiratory distress

Risk of cerebral palsy 4.5 times higher than in single pregnancies

Selective reduction in dichorionic twin pregnancies is recommended to be performed in the 12th week of pregnancy or in the 20th week of pregnancy.

Selective reduction at 12 weeks of gestation the abortion rate is 5% and the prematurity rate less than 33 weeks is 6%.

Selective reduction at 20 weeks the abortion rate is 14% and the prematurity rate less than 33 weeks is 20% [31–38].
