Risk of vascular complications in prophylactic compared to emergent resuscitative endovascular balloon occlusion of the aorta (REBOA) in the management of placenta accreta spectrum

To compare prophylactic and emergent resuscitative endovascular balloon occlusion of the aorta (REBOA) catheter placement in the management of placenta accreta spectrum (PAS).
Retrospective chart review of all patients with PAS (January 2018 to January 2020) at a single tertiary center who underwent prophylactic or emergent REBOA for cesarean hysterectomy for PAS.
A total of 16 pregnant patients with PAS underwent percutaneous REBOA placement by acute care surgeons in collaboration with a multi-disciplinary PAS team. The REBOA catheter was placed prophylactically in 11 cases and emergently in 5 cases. No complications occurred in the prophylactic placement group. In the emergent placement group, 3 of 4 surviving patients had vascular access site complications requiring intervention.
A multidisciplinary approach for the management of PAS utilizing REBOA is feasible in the setting of both planned and emergent cesarean hysterectomy and can aid in the control of acute hemorrhage. The risk for vascular access site complications related to REBOA catheter placement is higher in the emergent setting compared to prophylactic placement.
