Among these patients, 26 were treated conservatively, and 47 underwent surgical intervention. We next compared this IMH cohort with 154 patients with acute type A aortic dissection (AD) who were treated surgically during the same study period.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Computed tomography angiography revealed that the diameter of the ascending aorta of IMH patients treated with surgery was higher than IMH patients treated with conservative therapy (44.92\u2009\u00b1\u20097.58\u00a0mm vs. 51.22\u2009\u00b1\u200911.85\u00a0mm, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05), while there was no significant difference in other clinical parameters. The in-hospital mortality of patients with IMH who underwent surgical treatment was lower than those undergoing conservative treatment (0% vs. 11.5%, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05). The long-term mortality of the conservative IMH group was higher than the surgical IMH group (26.1% vs. 8.5%, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05). There was no significant difference in the surgical parameters and postoperative complications between AD and IMH surgery patients.

Thus, surgical intervention should be considered the primary treatment option if feasible. Furthermore, The safety of IMH surgery can be guaranteed just like AD.
