Objective: The aim of the study is to assess risk factors for hysterectomy among patients with placenta previa totalis (PPT).
Methods: The medical records of all patients delivered by cesarean section (CS) for PPT were retrospectively reviewed. Eligible cases were divided into those who underwent peripartum hysterectomy (PH) and those who did not. The two groups were compared in terms of demographics, operative features and perinatal outcomes. Logistic regression analysis was used to identify risk factors associated with hysterectomy.
Results: PH was performed in 43 (44.7%) patients with PPT. Referral patients were older when compared with those without hysterectomy (p: 0.029). The median values for gravidity, parity, number of live children and previous CS were statistically significantly higher in the hysterectomy group (p<0.05). Perioperative need for blood transfusion, anteriorly placed placenta and abnormal placental invasion were statistically significantly more frequent in the hysterectomy group (p<0.001). Intraoperative complication rate was higher in this group, and bladder injury was the most common complication. No significant differences were observed between the groups in terms of perinatal outcomes. In binomial logistic regression analysis; advanced maternal age (≥ 31 years), number of previous CS (≥2), preoperative need for blood transfusion, and abnormal placental invasion were found to be independent risk factors for PH in patients with PPT.
Conclusion: The findings of this study suggest that placenta invasion anomaly, advanced maternal age, increased number of previous CS, and increased need for blood transfusion are important risk factors for PH in patients with PPT.
