Presentation Transcript

  1. LONG-TERM OUTCOMES FOLLOWING THORACIC AORTIC SURGERY: A POPULATION-BASED STUDY • Jennifer Higgins,1Caroll Co,2 Michael Janusz1 • 1 Division of Cardiovascular Surgery, University of British Columbia • 2 Cardiac Services British Columbia

  2. INTRODUCTION • Increasing frequency of aortic surgery • Introduction of endovascular techniques • Long-term outcomes following open aortic surgery largely unexplored • OBJECTIVE:To determine population-based long-term survival following open thoracic aortic surgery

  3. METHODS • Review of prospectively maintained provincial cardiac surgery database • Identified all adult patients undergoing thoracic aortic surgery in British Columbia since 1993 • Summary of baseline characteristics • Kaplan-Meier survival analysis for : • Entire group • Year of surgery • Urgency of surgery • Location of aorta requiring surgery • Multivariate analysis to identify risk factors

  4. RESULTS

  5. IN-HOSPITAL OUTCOMES

  6. MULTIVARIATE ANALYSIS

  7. CEREBRAL PROTECTION

  8. DISCUSSION • Advantages • Population-based study • Large sample size • Long-term (17 years) follow-up • Limitations • Retrospective review of prospectively maintained database

  9. CONCLUSIONS • Excellent long-term survival following elective aortic surgery • Improved survival in modern era • Among aortic arch patients, outcomes improved with either antegrade or retrograde cerebral perfusion, compared to hypothermic circulatory arrest alone • Possible benchmark to which new aortic interventions should be compared
