Clinical study on surgical treatment of pernicious central placenta previa: 23 cases reports

Abstract

Objective To explore operation method and standard treatment of pernicious central placenta previa in order to reducing bleeding. Methods Twenty-three cases of pernicious central placenta praevia diagnosed in the Maternal and Child Health Care Hospital of Foshan City were retrospectively analyzed from July 2009 to June 2011. Results There were 19 cases reserved uterine, including 13 cases without placenta accreta and 6 cases with placenta accreat. These cases reserved uterine by cesarean section on placental edge combining ligating ascending uterine artery, local excising placenta implantation, and B-Lynch uterine suture. Four cases were hysterectomy and placenta percreta, including 2 cases with hysterectomy and 2 cases with subtotal hysterectomy. The average amount of bleeding was 750 ± 355 ml in 23 cases and all newborns were alive. Conclusions Applying incision of cesarean section on placental edge combining ligating ascending uterine artery and (or) internal iliac artery and B-Lynch suture were the effective ways to reduce bleeding in pernicious central placenta previa cases.
