[Placenta accreta spectrum disorder: Management and morbidity in a French type-3 maternity]

Placenta accreta spectrum disorder (PASD) is a rare obstetrical pathology, however its incidence is increasing. Morbidity associated with PASD is still high. Even if hysterectomy is considered to be the reference standard treatment, the conservative treatment by leaving the placenta in situ is now an approved option. The objective was to describe management and morbidity of patients with PASD, during the decade, in our French high-level maternity.

It was a retrospective study of management and morbidity of PASD in our department between 2007 and 2017.

Forty-six PASD cases were admitted in our center. Thirty-three (71.7%) had a prenatal suspicion of PASD. Conservative treatment was considered for 22 patients (47.8%). It was successful in 12 cases (54.5%). Thirty-four (73.9%) had a primary hysterectomy, eight (17.3%) had a delayed hysterectomy, four (8.6%) had a uterine conservation. Primary Morbidity included 28 blood transfusions, 12 bladder injuries, 1 ureteral injury and 13 transfers to intensive care unit. Secondary morbidity after conservative treatment included two Hemorrhages (16.6%), five endometritis (41.6%) and three disseminated intravacular coagulations (25%).

Morbidity associated with this pathology is severe. Conservative treatment became an option for PASD. Thanks to a better antenatal diagnosis, it can be proposed to more women. Morbidity seems the same as other centers. Our rate of primary and secondary hysterectomy is higher than other centers. Conservative treatment seems an effective option for women who desire to preserve their fertility to avoid peripartum hysterectomy and its related morbidity and consequences on fertility.
