Proximal aortic surgery in the elderly population: Is advanced age a contraindication for surgery?

摘要

ObjectiveThe study objective was to describe the clinical outcomes of elderly patients undergoing ascending aortic surgery.MethodsPatients aged 70?years or older who underwent ascending aortic surgery between January 2002 and December 2013 were examined. Of 415 included patients, 285 were elderly patients (age 70-79?years) and 130 were very elderly (age ≥80?years). Logistic regression and Cox proportional hazards models were used to evaluate operative mortality and long-term survival, respectively.ResultsSurgical indications included aortic aneurysm (63.1%), calcified aorta with need for other cardiac procedure (26.4%), and type A dissection (10.5%). Compared with elderly patients, the very elderly patients had a higher burden of comorbidities and operative mortality (13% vs 7%, P?P?P??.05). Kaplan–Meier estimates of survival at 1 and 5?years were 85.6% and 72.6% for elderly patients versus 79.2% and 57.1% for the very elderly patients. Age was a strong risk variable for late mortality in the unadjusted and adjusted analyses.ConclusionsAfter adjusting for these comorbidities, the cause of aortic disease, and the type of procedure, age was not an independent predictor of operative mortality, but was strongly associated with reduced late survival. Thus, advanced age alone should not be an absolute contraindication for ascending aortic surgery.
