    Fig 1.

    A, STL view of the growing model and an enlarged view of the growing area. The growing area was detected by alignment of the aneurysm geometry. The alignment was assessed with the matching of surfaces in nonaneurysmal vessel segments between each model. B, STL view of the nongrowth model.
