The aim of this study was to assess the long-term clinical outcomes of chEVAR in emergency settings for patients with abdominal aortic aneurysms that have complex morphology.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This was a multicentre retrospective study that included all consecutive patients undergoing urgent chEVAR with at least one chimney\/parallel graft up to June 2021.

The mean(s.d.) number of chimneys used per patient was 1.6(0.7). Technical success was achieved in 90.6% of patients, with a 30-day mortality rate of 17.7%. The mean follow-up was 4(3)\u2005years. Estimated overall survival was 69 \u00b1 5% at 3\u2005years, 45 \u00b1 6% at 5\u2005years, and 32 \u00b1 6% at 7\u2005years. Freedom from aneurysm-related mortality was 58 \u00b1 6% at 5\u2005years and 53 \u00b1 6% at 7\u2005years. In patients surviving the perioperative 30-day interval, freedom from aneurysm-related mortality was 73 \u00b1 6% at 5\u2005years and 66 \u00b1 7% at 7\u2005years. Primary target vessel patency at 5 and 7\u2005years was 87 \u00b1 4%, with renal arteries most frequently affected. Late reinterventions occurred in 16.1% of patients, mostly for type Ia endoleaks (8 of 25 reinterventions (32%)) and type Ib endoleaks (5 of 25 reinterventions (20%)).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In this Parallel Endografting And Chimney Endovascular (PEACE) registry study, chEVAR was associated with a high rate of technical success and acceptable early outcomes, but, in the longer term, was associated with high rates of reintervention and mortality.
