Maternal and fetal outcomes in subsequent pregnancies of patients who underwent Acar-style conservative surgery for placenta accreata spectrum.

Objective: This study aims to compare the maternal and fetal outcomes in subsequent pregnancies of patients who underwent conservative surgery (fertility-sparing) for placenta accreta spectrum (PAS) and the current pregnancies of patients who had a previous cesarean section. It aims to evaluate the feasibility of conservative surgery.
Methods: The study was carried out between January 2011 and September 2021 at the Gynecology and Obstetrics Clinic of Necmettin Erbakan University Meram Medical Faculty Hospital. The files of patients who underwent uterine segmental resection surgery with the diagnosis of PAS and then became pregnant again and who underwent cesarean section were retrospectively scanned from the hospital electronic registry system of patients without a PAS diagnosis but with a history of at least one previous cesarean section.
Results: Gestational week, birth weight, intrauterine growth retardation, and APGAR values were compared regarding the fetal outcomes and no statistically significant difference was found between the two groups. Seven patients in the study group and one patient in the control group required postpartum transfusions (P = 0.026), and urinary system infections were more frequent in patients with a history of PAS (P = 0.038).
Conclusion: Although cesarean hysterectomy is the standard treatment method in cases of placental invasion anomaly, conservative (uterus-sparing) surgery seems to be applicable in fertile patients despite surgical difficulties. Acar-style conservative surgery is important in terms of both fertility preservation in PAS cases.
