We stratified the population based on treatment extent: \u2018non-extended\u2019 (1 stent graft deployed), \u2018extended\u2019 (&amp;gt;1 stent graft deployed). Our primary outcomes were in-hospital spinal cord ischaemia and mortality. Secondarily, we evaluated procedure-related complications (endoleak, migration, fracture, compression, reinterventions), sac dynamics, rupture, and all-cause mortality at 1 and 5\u2009years. Sensitivity analysis was performed in patients without prior aortic procedures.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>Of 170 procedures, 78 (46%) were extended (median 2 [range 2\u20135] stent-grafts). Extended and non-extended treatment had similar rates of complicated presentations (53% vs 64%; P\u2009=\u20090.13). Compared with non-extended treatment, extended treatment had similar in-hospital rates of spinal cord ischaemia (2.6% vs 2.2%; P\u2009=\u20091) and mortality (2.6% vs 2.2%, P\u2009=\u20091). Additionally, extended treatment had not statistically different sac expansion rates, (1 year: 14% vs 23%, P\u00a0=0.80; 5 years: 16% vs 32%, P=0.29) and rupture risk (1 year: 1.3% vs 3.3%, P\u2009=\u20090.63), similar procedure-related complications (endoleak, migration, fracture, compression, reinterventions; all P\u2009&amp;gt;\u20090.05) and all-cause mortality (1 year: 10% vs 7.6%, P=0.54; 5 years: 19% vs 21%, P=0.82).
