Objective To understand the complications and outcomes of different types of twin pregnancies. Methods A retrospective analysis of 332 cases of twin pregnancy data. Results The incidence of twin pregnancy was 8.6 3 ‰. Pregnancy-induced hypertension, premature rupture of membranes, anemia, premature delivery and postpartum hemorrhage were the most common complications. There was no significant difference between twins and twins. The incidence of single-fetus twins in one fetus was higher than that of twins χ2 = 5 .30 8. The average number of twins in the second-term fetuses was lower than those in twins by t = 2.45 (P <0. 05). Conclusion Twin pregnancies pose a certain threat to maternal and fetus.
