OBJECTIVE: Examination of modalities and results of conservative treatment of placenta accreta. MATERIAL AND METHOD: Ten-year hospital records were reviewed, with analysis of patients who had diagnosis of placenta accreta associated with conservative treatment. RESULTS: During the study period, 21259 deliveries were registered, with an incidence of placenta accreta of 1 per 1 000 deliveries (n=23). Conservative treatment was applied in 13 patients. All of them had factors commonly associated with placenta accreta: prior cesarean sections (7/13), prior curettage or endouterine surgery (11/13), placenta praevia (11/13). Antenatal diagnosis was performed in only 64% of the cases (n=7). In our conservative strategy, placenta accreta was always left in situ, with an associated treatment in most of cases (n=10): Bilateral hypogastric artery ligation (n=7), medical treatment with methotrexate (n=5), uterine artery embolization (n=2). There was no case of maternal mortality. Conservative treatment was successful in 11 patients. It failed in 2 cases: hysterectomy was performed in one case for life-threatening hemorrhage, and in the other case for post-embolization uterine necrosis. The morbidity described was blood transfusion (n=7), endometritis (n=1), and one late hemorrhage with expelling necrotic tissue. Afterwards, 2 women became pregnant: one miscarriage and one normal term delivery. CONCLUSION: Conservative treatment of placenta accreta appears to be a efficient way to preserve fertility. Antepartum diagnosis should be improved among patients with a high risk of placenta accreta in order to optimize conservative strategy.
