Stent Graft Dislocation after EVAR Treated with an Endostapling Fixation System.

ABSTRACT

Stent-graft migration and type I endoleak are major complications after endovascular aneurysm repair (EVAR). We present a case of an 88-year-old female patient with a 56-mm-diameter progredient infrarenal AAA, with severely angulated proximal aneurysm neck and iliac arteries. EVAR was performed using a Gore Excluder stent-graft. -Computed tomography angiography (CTA) at one week postoperatively demonstrated a dislocation of the stent-graft and a proximal Type I endoleak. Placement of a proximal cuff with the use of 6 endostaples resulted in proximal neck seal and exclusion of the endoleak. CTA 2 years postoperatively showed no signs of a proximal type I endoleak. Use of an endostapling fixation system is a viable treatment option in cases of stent-graft dislocation resulting from angulation of the proximal neck.
