BACKGROUND: The prevalence of placenta previa is rising, and the best method for termination of affected pregnancies in mid-trimester remains controversial. The aim of this study was to summarize the method of labor induction in mid-trimester termination of pregnancy complicated by complete placenta previa by reviewing 2 cases and consulting the literature.
CASES: We retrospectively analyzed the clinical data of 2 patients with placenta previa who underwent vaginal delivery. Labor inductions for vaginal delivery in the 2 patients with placenta previa were successful, no uncontrollable bleeding occurred, and cesarean sections and removal of the uterus were avoided.

CONCLUSION: For patients with complete placenta previa during the second trimester, transvaginal operation for pregnancy termination under the condition of planned and adequate preparation may be a safe and effective treatment. Uterine artery embolization is not required for any patient. Fetal intracardiac injection of potassium chloride may be a suitable method for midtrimester termination of pregnancy complicated by complete placenta previa. However, our study results require further confirmation through additional clinical data.
