OBJECTIVE: To investigate the surgical outcomes of hybrid total arch repair without deep hypothermic circulatory arrest for patients with acute Stanford type A aortic dissection. METHODS: Retrospective review of clinical data of patients with acute Stanford type A aortic dissection who underwent surgical repair at our institution between November 2009 and December 2011 identified 21 patients who underwent hybrid total arch repair without deep hypothermic circulatory arrest. The in-hospital and follow-up data were investigated. Postoperative serial computed tomography angiography was used to evaluate the fate of true and false lumen in arch and descending aorta. RESULTS: Mean follow-up was 13.8 months (range, 3 to 21 months). The 1- and 12-month survival rates (by Kaplan-Meier analysis) were 95.2% (95% confidence interval, 86.2%-100%) and 90.5% (95% confidence interval, 78.0%-100%), respectively. No endograft caudal migration occurred. One patient with type I endoleak was successfully resolved during operation. There was no late rupture or paraplegia. CONCLUSIONS: Hybrid total arch repair without deep hypothermic circulatory arrest offers a promising alternative to risk reduction of complications during the postoperative period and late adverse events resulting from false lumen enlargement in the arch and descending aorta.
