This study tried to expand upon what they describe as the classic triad of signs to diagnose ruptured AAA “(1) abdominal pain, (2) hypotension and (3) a pulsatile abdominal mass”. They tested these against the _modified abdominal aortic aneurysm rupture signs. “_The MARS-signs encompassed (1) the registered pain-associated symptoms or signs, (2) all hypovolemic associated signs, and (3) pulsatile abdominal mass and/or ultrasound finding”. The MARS did slightly better in identifying ruptured AAA retrospectively. For me, this doesn’t add a great deal of help in making this can’t miss diagnosis and further work is necessary.
