Abstract
PURPOSE: In this study, we compared the early results between the extensive arch repair with a novel two-branched stent graft (TSG) and the traditional technique. METHODS: Between 2013 July and 2015 March, 63 acute type A aortic dissection (ATAAD) patients from four cardiac centers with indications for extensive arch repair were included in this study. Finally, 28 patients were involved in the traditional procedure (TP) group (23 males with the age of 49.75 ± 9.26 years) and 35 patients were involved in the TSG group (29 males with the age of 53.82 ± 8.17 years). RESULTS: The operation was successful in all patients. The selective cerebral perfusion time, total operation time, and chest drainage within 24 hours after the operation in the TSG group were significantly less than those in the TP group (P ≤0.05). The mean follow-up time was 11.17 ± 1.74 months in the TP group and 11.94 ± 4.29 months in the TSG group. No statistical differences were found in aortic diameter, false lumen diameter, and true lumen diameter at the diaphragmatic level during the follow-up. CONCLUSION: Our technique with a novel TSG simplified the extensive arch repair procedure and was an effective way for the treatment of ATAAD.
