Management of patients with placenta accreta spectrum disorders who underwent pregnancy terminations in the second trimester: A retrospective study.

PURPOSE

To analyse the management of patients with placenta accreta spectrum (PAS) disorders who underwent 2 trimester pregnancy terminations.

METHOD

The records of patients with PAS disorders who underwent 2 trimester pregnancy terminations were collected and analysed.

RESULTS

Twenty-eight patients were included; 8 (28.6%) patients received prenatal diagnoses and 20 (71.4%) patients received postnatal diagnoses. In the prenatal diagnosis group, scheduling hysterotomy and placenta removal were performed in 5 patients with complete placenta previa and previous caesarean delivery without hysterectomy or postpartum haemorrhage, and medical termination was performed in 3 patients, 2 of whom retained the placenta in situ. In the postnatal diagnosis group, the placenta remained in situ in 11 patients, and in 13 (46.4%) patients overall, adjuvant treatments were applied to the patients, and the abnormally implanted placenta was passed 43.5 (range: 7-102) days after termination. A complication associated with the placenta left in situ included intrauterine infection in one case. Uterus preservation was achieved in all the patients.

CONCLUSIONS

For patients with PAS disorders with complete placenta previa and previous caesarean delivery, hysterotomy is a safe choice for terminating a 2 trimester pregnancy. When it is impossible to manually remove the placenta, leaving the placenta in situ with the administration of adjuvant treatment is a good choice for uterus preservation.
