Objective To compare the clinical features and pregnancy outcomes of different chorionic twin pregnancies in our hospital from 2016 to 2020. Methods The data of the number of pregnant women, the number of twin pregnancies, the number of different chorionic twins, the clinical characteristics and pregnancy outcomes of different chorionic types were collected for retrospective statistical analysis in 5 years. Results (1) From 2016 to 2020, 42,505 pregnant women gave birth, and the incidence of twins was 1.24%; (2) the proportion of double-wool double sheep was 66.79%, which was higher than that of single-wool double-wool sheep, which was 33.21%; (3) single-wool double-wool double sheep was 65.14%. % preterm birth rate was 47.16% higher than that of double-wool double sheep (P<0.01); (4) There were 8 main complications of pregnant women during pregnancy, and the incidence rate of single-wool double sheep was 58.80% higher than that of double-wool double sheep, 50.57%, no statistics. (P=0.072); (5) The incidence rate of preterm low birth weight infants with single cashmere double sheep was 44.29% higher than that of double cashmere double sheep, 31.68%, with a statistical difference (P<0.01). Intrauterine growth restriction of the former was 16.29% higher than that of the latter, 12.64%, with no statistical difference (P=0.107). However, there was no statistical difference (P=0.230); (7) the incidence rate of single-wool double sheep in defective children was 4.29% higher than that of double-wool double sheep at 1.78%, with a statistical difference (P=0.012). Conclusion In strict accordance with the guidelines for the diagnosis and treatment of twin pregnancy, individualized and standardized pregnancy diagnosis and treatment of different chorionic twins can reduce the incidence of complications of monochorionic twins to the level of dichorionic twins.
