Of the 162 total cases, this study focused on the 135 patients who were assessed using computed tomography and aortic angiography. We have mainly employed direct anastomosis (direct), patch augmentation using an autologous pericardium (patch) and the chimney technique (chimney: another autologous reconstruction) as the methods for aortic arch reconstructions. According to the configurations of the postoperative aorta, arch geometry was defined as the Gothic, Crenel and Romanesque types. The following parameters were analysed: rates of intervention for recurrent coarctation (re-CoA), aortic distensibility and degree of tapering in the reconstructed aortic arch.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>The Gothic, Crenel and Romanesque were observed in 18 (13.3%), 48 (35.6%) and 69 (51.1%) patients, respectively. Direct tends to induce Gothic configuration, whereas the Romanesque was frequently observed in the chimney. Direct (23.5%) and Gothic (33.3%) showed higher rates of re-CoA, while the chimney (1.8%) showed a lower rate. Furthermore, distensibility was higher in chimney (5.3\u2009mmHg\u22121 in median) compared to the 2 other methods (direct: 3.2\u2009mmHg\u22121, patch: 2.1\u2009mmHg\u22121 in median). Additionally, the chimney showed lower tapering of the reconstructed aortic arch (chimney: 2.9\u2009mm vs direct: 4.1\u2009mm and patch: 3.5\u2009mm in median).<\/jats:p>\n
