Abstract

Compared to singleton pregnancies, twin pregnancies have a greater chance of congenital and structural defects, as well as pregnancy problems such miscarriage, stillbirth, and intrauterine foetal death. Carrying a foetus with severe abnormalities or sabnormal karyotype exposes the remaining healthy foetus at an even higher risk of unfavourable outcome and pregnancy problems. Increased risks for the mother and the babies might result from twin pregnancy and maternal medical issues or a difficult obstetric history. To our knowledge, no prior research have assessed and contrasted the outcomes of all dichorionic twin pregnancies, contrasted the outcomes of reduced twins with those of nonreduced and main singletons in a national cohort, or done a comparison of reduced twins with nonreduced twins. When counselling couples regarding foetal reduction and its effects, these findings are crucial for physicians.
