Follow-up of aortic diameter by IVDSA.

<p>Aneurysm and proximal stenosis was obvious in Group A after 3 weeks (a). Aneurysm enlarged further and stenosis disappeared in Group A after 15 weeks (b). (c) Profile of diameter changes indicated that Aneurysm groups dilated progressively, but diameter enlargement in Group A was significantly lower than in Group B at 7 weeks. *** <i>p</i> < 0.0001, Group B compared with Group A and SHAM group; +++ <i>p</i> < 0.0001, Group A compared with SHAM group.
