Resuscitative endovascular balloon occlusion of the aorta: A novel approach for treating amniotic fluid embolism with disseminated intravascular coagulopathy-A report of two cases.

We present two critical cases of life-threatening postpartum hemorrhage (PPH) due to amniotic fluid embolism (AFE) complicated by disseminated intravascular coagulopathy (DIC). These cases are the first to show the effectiveness of resuscitative endovascular balloon occlusion of the aorta (REBOA) for patient survival. In Case 1, the patient, experiencing critical conditions with severe PPH and DIC despite conventional treatments, including rapid blood transfusion and fibrinogen concentrate, was air-transferred to our hospital, where REBOA was promptly employed before hysterectomy was completed. Case 2 involved an ambulance-transferred patient with massive PPH and DIC despite conventional treatments. Prehospital REBOA was performed to prevent cardiac arrest during transfer, and hysterectomy was performed in the hospital. Given the rapid deterioration associated with AFE, REBOA can serve as a bridge until complete hemostasis to maintain vital signs and control bleeding in patients unresponsive to standard therapies before hemostatic interventions or during transfer.
