In the event of a ruptured abdominal aortic aneurysm, what is the emergent management strategy?

• A. Wait and monitor vitals; schedule elective repair.
• B. Rapid hemodynamic stabilization and urgent repair with open surgery or emergent EVAR based on anatomy and availability.
• C. Administer only antiplatelets; no imaging.
• D. Apply external compression to abdomen.

Answer: (B)

When a rupture occurs, the priority is immediate stabilization and rapid control of bleeding with definitive repair as soon as possible. This means activating a massive transfusion protocol, securing the airway, establishing quick IV access, and resuscitating to maintain perfusion without delaying hemorrhage control. The repair should happen urgently, using the best route available: open surgical repair or emergent endovascular aneurysm repair (EVAR) depending on the patient's anatomy and the resources and expertise at hand. If the aneurysm anatomy is favorable for EVAR and the endovascular team and setup are ready, EVAR can be faster and avoid a laparotomy; if not, open repair is pursued. Imaging like CT can guide planning, but in a unstable patient that would delay care and is not prioritized over immediate repair. External abdominal compression won’t stop a ruptured AAA and is not an effective treatment.

So the correct approach is to rapidly stabilize and proceed to urgent repair via open surgery or EVAR based on anatomy and availability.
