Abstract [en]

Aim. The aim of this paper was to evaluate early outcome of the GORE (R) EXCLUDER (R) AAA Endoprosthesis featuring C3 Delivery System in subjects with aortic neck anatomy outside IFU. Methods. Individual patient data prospectively collected over a 2 year period from the Global Registry for Endovascular Aortic Treatment (GREAT). For each subject a minimum data set was collected containing demographic, pre/intra- and postoperative variables. Main outcome measures were successful exclusion of the AAA and occurrence of any major endoleak at 1 month. In this study, outside IFU was defined as aortic neck length less than 15 mm and/or aortic neck angle greater than 60 degrees. Results. A total of 400 subjects, (86.6% male, mean age 73.9 years). Primary pathology was AAA in 94.2% with 98.2% undergoing EVAR as a primary procedure. Sixty-eight subjects underwent EVAR outside IFU (neck length <15 nun N.=32, neck angle >60 degrees N.=47 and neck length <15 nun and angle >60 degrees N.=11). The graft was successfully deployed within 5 nun of its intended location in 63 (94%) cases utilising a total of 33 repositioning episodes. Eight aortic cuffs were used, 5 to treat a type 1 endoleak. At 30 days we recorded 2 type 2 endoleaks both successfully treated and 1 type 1b also successfully treated. There were 2 deaths, one in each group. Conclusion. GORE (R) EXCLUDER (R) AAA Endoprosthesis featuring C3 Delivery System allows re-positioning to be performed safely in cases outside IFU. Repositioning is an effective operative manoeuvre and facilitates EVAR in challenging anatomy. Longer follow-up is required to evaluate the durability of these results at 30 days.
