January 1986 ~ June 1991 were treated 201 cases of placenta previa, accounting for 1.26% of the total number of deliveries over the same period. There were 32 primiparas (15.92%), 169 mothers (84.08%) and 69 cases (34.33%) of abortion. There were 37 cases (18.41%) with central placenta previa, 117 cases (58.21%) partially, and 47 cases (23.38%) marginalized. Among 152 cases (75.63%) of cesarean delivery and 49 cases (24.38%) of vaginal delivery, 8 cases of central placenta previa had died and “placenta accreta” vaginal delivery. One patient died of hemorrhagic shock, with a case fatality rate of 0.5%, 19 neonatal deaths and a case fatality rate of 9.31%. Finally, combined with the clinical practice of primary hospitals, the reasons for placenta previa, the way of termination of pregnancy and bleeding in cesarean section and other issues were discussed.
