  2. Objective To evaluate the early and late clinical outcomes of two different surgical techniques for repair of acute type A dissection: • open distal anastomosis under deep hypothermic circulatory arrest (DHCA) and • distal aortic clamping on moderate hypothermic cardiopulmonary bypass (ACPB)

  3. Acute Aortic Dissection Type A (Stanford) Inspection of the arch for additional intimal tear No Yes Study Group Patient Exclusion ACPB (n=42) DHCA (n=82)

  6. Operative Characteristics II DHCA ACPB P N (n=82) (n=42) Arterial Cannulation Axillary a 16% 10% 0.70 Femoral a 76% 83% Other 8% 7% ACP 22% ------ RCP 10% ------ Circ Arrest Time 23+15 <1min <0.001 (Mean/SD) (ACP= Antegrade cerebral perfusion, RCP= retrograde cerebral perfusion)

  8. Freedom from Death at 5 Years 1.0 DHCA ACPB 0.9 0.8 Death Free Probability 0.7 Log Rank p = 0.99 0.6 0.5 1 2 3 4 5 Time to Death (in years) 30 day 1 year 2 years 3 years 4 years 5 years DHCA (N=42) 34 (81%) 31 (74%) 31 (74%) 31 (74%) 31 (74%) 31 (74%) ACPB (N=82) 67 (82%) 62 (76%) 61 (74%) 60 (73%) 60 (73%) 60 (73%)

  9. Conclusion • No significant differences in operative mortality, major morbidity and actuarial 5-year survival were observed between DHCA and ACPB. • However, there are some practical technical advantages if the distal anastomosis is performed with an open manner • More studies are required to determine the fate of the false lumen and the incidence of dissecting aneurysms with the two techniques.
