Abstract

OBJECTIVE
To suggest the pregnancy outcome data according to the types of placenta previa in order to establish the optimal management of placenta previa.
METHODS
A retrospective review of the clinical records of 179 women delivered with the diagnosis of placenta previa over 25 gestational weeks during the 6-year period from January 1, 1995 to December 31, 2000, at the Wonju Christian Hospital. We divided each groups into total, partial and marginal placenta previa in order to compare pregnancy outcomes.
RESULTS
There were significant differences in the numbers of gravida, prior abortion, number of previous cesarean section between marginal and total placenta previa group. There were no significant differences in the gestational weeks at delivery, blood transfusion units, birth weight and placenta/birth weight ratio among each group. Statistically significant frequent hysterectomy in case of partial palcenta previa in comparison to marginal placenta previa was performed. Significant differences of the prior cesarean section (86.4% vs 3.8%) and placenta accreta (45.4% vs 37.5%) were noted between hysterectomy group and no hysterectomy group.
CONCLUSION
Previous cesarean section history is strongly associated with cesarean hysterectomy. Women with placenta previa and history of previous cesarean section have more risk of placenta accreta. So, we should prepare sufficiently for cesarean hysterectomy in such cases.
