Note. - Table 2 shows the incidence of helix and vortex flow in the AAo (ascending aorta), aortic arch and DAo (descending aorta) of the three study cohorts.

*: significant differences (p<.05) between aneurysm patients and age-matched controls.

#: significant differences (p<.05) between aneurysm patients and healthy volunteers.

+: significant differences (p<.05) between age matched controls and healthy volunteers.
