A prospective study of anatomico-pathological changes in abdominal aortic aneurysms following endoluminal repair: is the aneurysmal process reversed?
We conclude that in early follow up AAA which diminish in diameter following endoluminal repair remain isolated from the general circulation. Co-incident with this decrease in AAA diameter, the proximal and distal necks increase in diameter but do not undergo any shortening in length. This paradoxical increase in neck diameter, was not progressive in the period of follow-up.
Our data show that the modified curved cavopulmonary connection is hydrodynamically advantageous but might impair caval fluid mixing in younger children.
