Ruptured abdominal aortic aneurysm (rAAA) carries high morbidity and mortality. Advances in endovascular techniques in the last two decades allow for minimally invasive approach for repair of these aneurysms. A succinct but comprehensive pre-operative is essential for delivery of a safe anesthetic for the patient with rAAA. Placement of proximal occlusion balloon in the descending aorta using the rapid control technique can be life-saving. Endovascular aortic repair (EVAR) can be performed under monitored anesthesia care using local anesthetic and IV sedation, and with fewer invasive lines. However, rapid conversion to general endotracheal anesthesia should be expected. Anesthesiologists should be familiar with the hemodynamic management of rAAA and be ready to provide resuscitation to correct for anemia, coagulopathy, and acidemia. In addition, the anesthesiologist should be aware of the common complications related to EVAR, including abdominal compartment syndrome, distal ischemia, and local vessel injury.
