Background: Perioperative proximal endoleaks during endovascular aneurysm repair potentiate graft migration, aneurysm sac expansion, and stent-graft failure. Adjunctive placement of a Palmaz stent at the proximal landing zone can improve proximal seal and eliminate perigraft flow; however, the long-term sequelae associated with this maneuver are unknown. We sought to evaluate the effect of Palmaz stent placement for type Ia endoleaks on delayed endoleak formation, graft migration, and aneurysm expansion.

Methods: A retrospective cohort review of a prospectively maintained database was performed. Between 2000 and 2005, all consecutive patients who had undergone infrarenal endovascular aneurysm repair were evaluated for a type I endoleak that was treated with Palmaz stent placement. Fenestrated, juxtarenal, and investigational devices were excluded from the analysis. Postoperative and follow-up ax...
