Primary endpoints consisted of technical (correct deployment of the stent-graft) and clinical (false lumen occlusion) success. Secondary endpoints included overall survival and morbidity after 30 days. In 12 patients, follow-up computed tomography angiogram (CTA) was available and aortic remodeling was evaluated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>We identified 16 eligible patients (75% men, mean age: 69 years, range: 52\u201380 years). Technical success was 94%. Overall survival after 30 days was 100%; there was 1 aortic reintervention (additional false lumen embolization due to endoleak type 1a in 1 patient). Median total follow-up was 31.5 months (range: 3\u201366 months). Four (25%) of 16 patients died during follow-up, in 3 of those patients the cause of death is unknown, and 1 patient developed cardiac tamponade after being treated by fenestrated thoracic endovascular aortic repair. Imaging follow-up with CTA was available in 12 patients (median imaging follow-up: 27.5 months, range: 1\u201357 months). Nine (75%) of 12 patients showed thoracic aortic remodeling, and in 3 patients aneurysm size was stable. No patient showed aneurysm growth.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The
