Background— The site of cannulation for repair of ascending aortic dissection remains controversial. We present our experience with ascending aortic cannulation for acute aortic dissection type A.

Methods and Results— From January 1988 to September 2007, we operated on 242 patients for acute aortic dissection type A. Medical records of 235 patients who received ascending aortic cannulation or femoral cannulation were retrospectively reviewed. Long-term follow-up was complete in 97% of patients. Cannulation was accomplished in 82 patients through the ascending aorta and in 153 patients through the femoral artery. Preoperative patient characteristics were almost comparable between groups. Similarly, there were no differences in preoperative patient characteristics and intraoperative parameters including operation time, bypass time, cross-clamp time, hypothermic circulatory arrest time, and percentage of total arch replacement. The 30-day mortality rate was 14% in the aortic group and 23% in the femoral group (P=0.07), and incidence of stroke was 4.9% in the aortic group and 4.5% in the femoral group (P=0.86). During follow-up (mean, 5.5 years), survival at 5 years and 10 years was 65% and 41% in the aortic group and 64% and 46% in the femoral group, respectively (P=0.97).

Conclusions— The cannulation site should be chosen according to the patient’s pathology and status, and the present study suggests that ascending cannulation in patients with acute aortic dissection type A can be a safe alternative, offering acceptable early and long-term outcomes.
