AAA, Abdominal aortic aneurysm; AP, anteroposterior; CEA, carotid endarterectomy; COPD, chronic obstructive pulmonary disease.
Continuous variables are presented as mean ± standard deviation.
Elective vs symptomatic
symptomatic vs rupture; P value from F-test in analysis of variance for continuous variables and from χ2 test for categoric variables.
These values are significant (significant at level of .05).
