BACKGROUND AND OBJECTIVES: Stanford type A aortic dissection is a potentially catastrophic event that requires surgical repair, on an emergency basis. The extent of arch repair that should be carried out during emergency surgery of this type is controversial. This study was designed to evaluate the results of arch replacement carried out during acute type A dissection. SUBJECTS AND METHODS: 28 patients with Stanford type A dissection and who underwent arch replacement between 1995 and 2006 were reviewed. RESULTS: Hospital mortality was 3.6% (1 patient), and transient neurocognitive dysfunction was observed in 5 patients. During the follow-up period (mean 26+/-20 months; range 1 to 66 months), 3 patients underwent reoperation due to descending thoracic or abdominal aortic aneurysm. There was no late death. Follow up computed tomography was performed in 15 patients and false lumen disappeared totally or partially in 10 patients (66.7%). CONCLUSION: Arch replacement for acute Stanford type A dissection may decrease the risk of late complications related to false lumen and lead to an excellent midterm survival rate.
