Abstract
ObjectiveThe disease of the aortic arch is traditionally approached by open surgical repair requiring cardiopulmonary bypass and circulatory arrest. This study performed a retrospective analysis comparing outcomes through primary hybrid patients submitted to aortic arch surgery without cardiopulmonary bypass with patients submitted to conventional open surgery.Methods25 patients submitted to the aortic arch surgery were selected in the period 2003-2012 at the Madre Teresa Hospital in the city of Belo Horizonte, Brazil; 13 of these underwent hybrid technique without cardiopulmonary bypass and 12 underwent conventional open surgery.ResultsThe mortality rate for the hybrid group was 23% and for the conventional surgery group was 17% (P=0.248). The postoperative complication rate was also similar in both groups, with no significant difference.ConclusionBoth techniques proved to be similar in mortality and morbidity. However, due to the small sample, more analytical studies with larger samples and long-term follow-up are needed to clarify this issue.

Summary
Treating patients with aortic arch aneurysm is a major technical challenge and it is an area in continuous development and innovation[1]. The aortic arch aneurysm is a lethal disease[2,3,4,5] that represents 10% of thoracic aneurysms[3]. The surgical treatment, indicated in aneurysms larger than 6 cm[6,7], alters its natural course[8]. Surgery requires cardiopulmonary bypass (CPB) with deep hypothermic and circulatory arrest[1,9], with 65% to 80% of morbidity rates and mortality from 10% to 20% due to stroke, acute myocardial infarction (AMI), pulmonary complications and excessive bleeding[1,6,10].
