Eligibility criteria included an aortic neck diameter of 19\u201330\u2009mm, a minimum infrarenal neck length of 2\u2009mm, a total proximal sealing zone of at least 15\u2009mm, thrombus in the aortic neck in \u02c225% of the circumference, and maximum aortic angulations of 60\u00b0 in the infrarenal, 45\u00b0 in the suprarenal segment and \u02c245\u00b0 above the superior mesenteric artery.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>According to CE-approved inclusion criteria, 19 individuals (19%) would have been eligible for ChEVAR.
