Purpose. To determine the predictivity of anatomic and co-morbid factors fo
r peri-operative mortality of patients operated for a non-ruptured abdomina
l aortic aneurysm (AAA).
Methods. Between 1986 and 1996, data had been collected prospectively in a
computerized date base. A chi-square test was per formed for 5 anatomic, an
d 8 co-morbid criteria.
Results. 25 of 470 patients (5,3 %) died within one month after surgery. An
eurysm diameter (P = 0,004) and aneurysmal internal iliac artery (P = 0,019
) were associated with an increased mortality whereas upper extension of th
e disease necessitating a juxta-renal anastomosis, the need for inferior me
senteric artery reimplantation, or a symptomatic ilio-femoral occlusive dis
ease, were not. Age (P = 0,016), obesity (P = 0,03), alteration of left ven
tricular function (P = 0,0014), and preoperative renal failure (P = 0,0001)
were associated with increased mortality.
Conclusion. Both anatomic and co-morbid factors can predict outcome after e
lective surgery for non-ruptured AAA. The criteria might help to selection
patients who might benefit from endovascular treatment of AAA.
