Retrospective single centre observational cohort study of patients who underwent an elective infrarenal abdominal aortic aneurysm repair, from January 2011 to January 2020.
Objective: To evaluate the performance of the Endurant endoprothesis in patients with a wide or conical shaped neck anatomy after elective abdominal aortic aneurysm repair. Inclusion: Patients who underwent elective infrarenal abdominal aortic aneurysm repair with the Endurant endograft between January 2011 until January 2020 in Rijnstate, Arnhem, the Netherlands. Primary endpoint: Freedom from reinterventions at one year. Secondary outcomes: * Endoleaks * Aneurysm sac growth * Aneurysm rupture * Stent migration * AAA-related mortality * All-cause mortality * Procedural time * 30-day complications * Renal dysfunction/renal occlusion * Proximal fixation failure

endovascular repair of the AAA with the endurant stent graft
Rijnstate
Arnhem, Netherlands
Freedom from reinterventions at one year
reintervention-free survival will be evaulated using kaplan meier method
Time frame: one year
Freedom from reinterventions throughout follow-up (up to ten years)
Reintervention-free survival throughout all available follow-up will be evaluated using kaplan-meier methods
Time frame: 10 years
Number of endoleaks
All endoleaks will be registered throughout follow-up and will be presented by type of endoleak.
Time frame: 10 year follow-up
the number of patients showing aneurysm sac growth
Sac growth is defined as growth over 5 mm and will be presented for 1 year follow-up, 5 years follow-up and 10 year follow-up
Time frame: 10 year follow-up
the number of patients with an aneurysm rupture during follow-up
all ruptures that occur will be registered including outcome (death or successful repair)
Time frame: 10 year follow-up
the number of patients showing stent migration
stent migration will be documented in mm and will be presented for 1 year follow-up, 5 years follow-up and 10 year follow-up
Time frame: 10 year follow-up
Number of patients with AAA related mortality
All deaths related to the AAA will be documented
Time frame: 10 year follow-up
the number of patients showing proximal fixation failure

proximal fixation failure is defined as yes if type 1 endoleak or stent migration or aneurysm sac growth will occur and will be presented for 1 year follow-up, 5 years follow-up and 10 year follow-up
Time frame: 10 year follow-up
All-cause mortality
all deaths will be registered regardless their cause
Time frame: 10 year follow-up
The number of patients with 30-day complications
All complications during the first 30 days will be registered related to the procedure and will be listed for the different types of complications
Time frame: 30 days
The number of patients with renal dysfunction/renal occlusion
all clinical relevant declines in renal function will be documented, including renal artery stenosis or occlusion
Time frame: 10 year follow-up
