    Aneurysm Arturo — Abdominal Aortic Aneurysm

    Pulsatile abdominal mass, sudden tearing back pain, and a dropping BP — never palpate deeply once rupture is suspected

    Aneurysm Arturo, the MnemoNurse character for Abdominal Aortic Aneurysm

    Arturo, a 68-year-old smoker with longstanding hypertension, comes to the ED with sudden, severe back and abdominal pain, and the triage nurse feels a pulsatile mass just left of his umbilicus.

    Arturo's aortic wall has weakened and ballooned over years of untreated hypertension and smoking. Most AAAs are silent until they grow large enough to be felt as a pulsatile mass or until they rupture, producing sudden severe abdominal or back pain with hypotension. A ruptured AAA is a surgical emergency where the priority is rapid recognition, avoiding deep palpation, and getting the client to the operating room, not aggressive fluid resuscitation that can raise pressure against a leaking wall.

    The story arc

    1. The setup

      Arturo has smoked for 40 years and has poorly controlled hypertension, both major risk factors for aneurysmal degeneration of the aorta.

    2. The turn

      An incidental ultrasound during a routine visit shows a 4.8 cm infrarenal aortic aneurysm, and Arturo is scheduled for surveillance imaging every six months.

    3. The crisis

      Arturo suddenly develops tearing back and abdominal pain, his blood pressure drops to 82/54, and a pulsatile, tender abdominal mass is now palpable.

    4. The save

      The nurse avoids deep palpation of the abdomen, keeps Arturo NPO, obtains large-bore IV access with permissive hypotension fluid strategy, and the surgical team rushes him to emergent repair.
