Predictors of distal SG-induced new entry were analysed. End points were hospital- and midterm-follow-up results.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>The study comprised 109 patients with 46 (42.2%), 22 (20.2%) and 41 (37.6%) patients in groups Z, R and S, respectively. No significant differences were found in early outcomes. Freedom from distal SG-induced new entry was comparable in groups Z, R and S (68.9% vs 92.9% vs 100%, log-rank\u2009=\u20090.14). There was no significant difference in follow-up between the groups. Four-year survival rates were 80.44%, 71.59% and 95.06% in groups Z, R and S, respectively. On multivariable analysis, the presence of connective tissue disorders [hazard ratio (HR)\u2009=\u20095.62, P\u2009=\u20090.11] and SG diameter (HR\u2009=\u20091.37, P\u2009=\u20090.034) were strong predictors of distal SG-induced new entry.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>Dissection-specific hybrid SG with a soft distal end is effective in patients with non-acute DeBakey type I aortic dissection.
