Abstract

Objective The most common treatment for placenta accreta spectrum (PAS) disorders is planned primary cesarean hysterectomy. However, other management strategies may improve outcomes and/or allow fertility preservation. The objective of this study was to describe the course and outcomes of patients with PAS managed by leaving the placenta in situ. Study Design This is a series of 11 patients with PAS managed by leaving the placenta in situ at a single academic center in the United States from 2015 to 2022. The approach described involves delivery of the fetus via cesarean, no attempt at placental removal, closure of the hysterotomy, prophylactic intravenous antibiotics for up to 1 week, and close outpatient follow-up until the uterus is empty. Results The uterus was successfully preserved in six (55%), minimally invasive hysterectomy was performed in four (36%), and abdominal hysterectomy was performed in 1 (9%). During cesarean delivery, the median estimated blood loss was 650mL (range: 200–1,000mL). The majority of patients had no vaginal discharge for several weeks after delivery, followed by brown or bloody discharge, and intermittent mild-to-moderate cramping. The median time to resolution of PAS was 18 weeks in patients with successful uterine preservation (range: 5–25 weeks). Indications for hysterectomy included hemorrhage (n=1), coagulopathy (n=1), endomyometritis (n=2), and pain (n=1), and these occurred at a median of 5 weeks postpartum (range: 1–25 weeks). Four patients had subsequent pregnancies of whom three were live births at or near term and one was a spontaneous abortion at 19 weeks. Conclusion Leaving the placenta in situ may be an appropriate management strategy for some carefully selected and counseled patients with PAS. Key Points
