Acute type a aortic dissection: 18 Years of experience in one center (Hospital 12 de Octubre)

Abstract

Here, we review our experience in acute type A aortic dissection analyzing the role of antegrade brain protection. A total of 105 patients underwent surgery for acute type A aortic dissection between March 1990 and October 2008. An open technique with deep hypothermia was used in 81 patients. Deep hypothermia alone was induced in 32 patients; in combination with retrograde cerebral perfusion in 26 patients and in combination with antegrade cerebral perfusion (ACP) in the final 23 patients. The overall hospital mortality rate was 15%. Hospital mortality risk factors were age ≥70 years and preoperative shock (P<0.05). Hospital mortality was reduced to 9% in the last 23 consecutive patients in whom ACP was accomplished (P<0.05). Survival rate after 1, 5, 10 and 15 years of follow-up was 97.6±1.7%, 84.3±4.4%, 60.7±7.5% and 57.1±7.8%, respectively. The only late death risk predictor was the non-use of ACP (P=0.05). Surgery for acute aortic dissection provides excellent results. ACP via the axillary artery improves the prognosis for these patients and should be the brain protection method of choice.
