All 13 patients were male, age 52.6\u00b110.4\u2009years. The implantation time was 14.0\u00b16.9\u2009minutes; total procedure time was 89.5\u00b119.8\u2009minutes. The volume of contrast was 79.6\u00b17.2\u2009ml. And 15 aortic stent-grafts were implanted, and all 13 patients had chimney branch stent-grafts implanted into the left subclavian artery (LSA). There were 3 (23.1%) cases of immediate type \u0399a endoleak after thoracic endovascular aortic repair (TEVAR), and 7.7% type \u0399a endoleaks occurred in delayed fashion. Survival at 2\u2009years was 100%, and the 2-year patency of chimney stent-grafts was 100%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>This study reports early success with good freedom from endoleak using a novel stent-graft designed for chimney TEVAR to treat aortic arch dissection.
