Key result
REBOA for managing placenta accreta spectrum lacks quantitative outcomes in this observational report.
Why the study?
Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) has recently been used to limit peripartum bleeding in placenta accreta spectrum, but established guidelines for its use are lacking.
Observational
Yes
Supports ultrasound-guided REBOA for faster placement in PAS; leaves open optimal anaesthetic protocols pending prospective trials.
( Eur J Anaesthesiol . 2025 Sep 1;42(9):791–799. doi: 10.1097/EJA.0000000000002218) Placenta accreta spectrum (PAS), a condition where the placenta invades partially or completely into and through the myometrium, can be extremely challenging because of the risk of significant peripartum bleeding (PPH). Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) has recently been implemented to help limit PPH in patients with PAS. REBOA uses an endovascular balloon to cause a temporary aortic occlusion to lower blood loss during cesarean delivery (CD) and prevent potential hysterectomy in certain cases. Currently, there are no established guidelines for its use in managing PAS cases.

Azem et al. (2026) conducted an observational in Placenta accreta spectrum (PAS). Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) was evaluated. The use of REBOA for managing placenta accreta spectrum was discussed, but no quantitative results were reported in the abstract.
