Fig 1 A, Aneurysmal wall remaining postinterposition of synthetic prosthesis. B, Removal of the fragment with the largest possible dimensions, being the greatest dimension coincident with the longitudinal axis of the aorta.

Fig 5 Elastic diagram of individual specimens of abdominal aortic aneurysms (AAA) obtained in vivo and normal aorta from a cadaver: load (N) in the vertical axis and distension (mm) in the horizontal axis. The purple, green, yellow, and red lines are from specimens from larger or smaller individual AAA used in this study from asymptomatic (AST) or symptomatic (ST) patients. The blue line shows data from the same biomechanical test with tissue from normal, not aneurysmatic aorta from a cadaver.
