The primary end point was the occurrence of a T1EL. The gap between a virtual aorta and the patient's aortic wall at the stent graft fixation was calculated over the whole circumference at 1\u2009mm intervals, and gap distribution mapping was performed. The rate of freedom from a T1EL was estimated using the Kaplan\u2013Meier method and compared between the patients with or without a continuously malapposed region of &amp;gt;1\u2009mm from the branches to the aneurysm.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>Twenty-one patients were analysed. During the mean follow-up period of 21.7\u2009months, 4 patients were confirmed to have T1ELs. Three of the T1Els were detected during the perioperative period and occurred through a fenestration. The remaining patient had a T1EL 2\u2009years postoperatively. The gap distribution mapping confirmed the presence of a continuously malapposed region of &amp;gt;1\u2009mm from the cervical branch to the aneurysm postoperatively in 4 patients with T1ELs. Patients who had a continuously malapposed region of &amp;gt;1\u2009mm showed a statistically lower T1EL rate than those without (p\u2009&amp;lt;\u20090.001). Malapposed regions defined using the gap distribution mapping were consistent with flow channels through T1EL fenestrations detected using the perioperative computed tomography data.<\/jats:p>\n
