Patients
All patients underwent endovascular AAA repair between January 2013 and
December 2019 were identified retrospectively from the database of
hospital records. Patient demographics, perioperative variables and
early and midterm outcomes were achieved from hospital database and
death certificates. All of the methods within this study were in
compliance with the declaration of Helsinki (7threvision, 2013) and were approved by the Institutional Review Board. The
requirement for the informed consent was waived due to the retrospective
nature of the study.
Indications for EVAR included (1) AAA > 5.5 cm in maximum
diameter, (2) saccular type of aneurysms and (3) symptomatic aneurysms.
Patients with hostile neck (which is defined as neck length ≤ 10 mm
and/or reverse conical shaped necks) were all included in the study.
