Caesarean section combined with temporary aortic balloon occlusion followed by uterine artery embolisation for the management of placenta accreta.
OBJECTIVE
To determine the efficacy and safety of caesarean section combined with temporary aortic balloon occlusion followed by uterine artery embolisation (UAE) for the treatment of patients with placenta accreta.


METHODS
This retrospective study involved 42 patients with placenta accreta. All patients underwent caesarean section combined with temporary aortic balloon occlusion followed by UAE through the right femoral approach.


RESULTS
All patients were confirmed to have placenta praevia and accreta, including five patients with placenta percreta, at the time of delivery. The technical success rate of the combined treatment was 97.6% (41/42). Forty-one patients underwent successful caesarean section with conservation of the uterus. Hysterectomy was required in one (3.1%) patient. The amount of blood loss and blood transfusion, and the operation time were was 586 ± 355 ml, 422 ± 83 ml and 65.5 ± 10.6 minutes, respectively. The mean postoperative hospital stay, occlusion time and fetal radiation dose were 5.5 ± 2.6 days, 22.4 ± 7.2 minutes and 4.2 ± 2.9 mGy, respectively. There were no significant changes before and 7 days after the endovascular procedure in creatinine levels (56.8 ± 13.8 μmol/l versus 63.4 ± 16.7 μmol/l, p = 0.09) or urea nitrogen (6.3 ± 2.5 μmol/l versus 7.4 ± 3.8 μmol/l, p = 0.17). There were no access-site complications after the endovascular procedure and no complications related to the intervention during follow-up.


CONCLUSIONS
Temporary aortic balloon occlusion followed by UAE can effectively control postpartum haemorrhage during placental dissection, and reduce transfusion requirements, hysterectomy rate, and operation time in patients with placenta accreta.
