Iliac fixation inhibits migration of both suprarenal and infrarenal aortic endografts

A, Measurement of preoperative aneurysm characteristics. B, Depiction of poststent image measurements.

Examples of good and bad iliac fixation. A, Infrarenal stent graft with good iliac fixation and no migration. B, Infrarenal stent graft with poor iliac fixation; migration was treated with iliac extender cuff placement, with no further migration. C, Suprarenal stent graft with good proximal and distal fixation and no migration. D, Suprarenal stent graft with good proximal and poor distal fixation; migration was treated with iliac extender cuff placement, with no subsequent migration.
