Background: Despite current aging of patients proposed for cardiac surgery, published results of type A dissection repair in the elderly are sparse and controversial though an increased operative risk when compared to younger patients is well-documented. Whether any patient of an advanced aged suffering from acute dissection of the proximal aorta should be referred for surgery deserves specific clinical studies. Objective: To define factors of poor outcome after repair of type A dissection in the elderly by focusing on both early and late results. Method: A retrospective study including a consecutive series of 83 patients operated on in two neighboring French university centers between 1988 and 1999 with similar outstanding methods. Complete follow-up was achieved in March 2000. Results were compared according to: (i) the presence or the absence of complications at admission; and (ii) the use of hypothermic circulatory arrest (HCA) for completion of the distal suture. Results: Mean age was 75.2±3.6 years (70–85). Overall operative mortality (OM) was 37.3%. OM was significantly higher (51.2 versus 23.8%, P=0.01) for patients who presented at admission any one of the following complications: tamponade, shock, endotracheal intubation upon arrival or evidence of brain, myocardial, mesenteric, renal or limb malperfusion. OM was not significantly affected by age or by the use of HCA during repair. Overall Kaplan–Meier survival was 50% at 1 year, 30% at 5 years and 13% at 10 years and was significantly lower (P=0.004) for patients who presented at least one complication at admission. Kaplan–Meier survival (excluding OM) was respectively 81, 48 and 21% and was significantly lower in case of prolonged stay in ICU (P=0.014) and for patients operated on without HCA (P=0.02). Conclusions: Results of repair of acute type A dissections in the elderly are acceptable for uncomplicated cases at admission. Using HCA in elderly patients whenever required for appropriate repair does not worsen early or late survival.
