BACKGROUND: A ruptured abdominal aortic aneurysm (rAAA) is fatal. While Resuscitative endovascular balloon occlusion of the aorta (REBOA) contributes to hemodynamic stability, organ ischemia should be carefully considered. CASE PRESENTATION: A 69-year-old obese man with untreated hypertension presented with sudden back pain and hypotension. Computed tomography confirmed the presence of an rAAA. REBOA was initially planned in Zone 1 via the left brachial artery but was eventually switched to Zone 3 via the right femoral artery. Hemodynamic stability was achieved through blood transfusion and partial REBOA, followed by surgical intervention. The postoperative recovery was uneventful. CONCLUSION: Zone 1 REBOA via the left brachial approach provided safe aortic occlusion. Transitioning to Zone 3 REBOA, combined with meticulous organ perfusion management and blood transfusion, prevented ischemia-reperfusion complications.
