While modern pioneers continue to push the boundaries of surgery to refine operative techniques, such rapid progress in surgical techniques has outpaced the availability of robust clinical evidence, despite voluminous observational studies.
The International Aortic Arch Surgery Study Group (IAASSG) has been formed by the collective desire of many arch surgeons to overcome the limitations in our existing knowledge, and through international multi-institutional collaborative projects, enhance our understanding of aortic arch surgery to bring better outcomes for our patients.
The main objectives of the International Aortic Arch Surgery Study Group are four-fold:
1) to determine the optimal neuroprotection strategies and operative parameters for patients undergoing hemi-arch and total arch surgery
2) to assess perioperative mortality, morbidities, and predictors for operative risk
3) to formulate a risk predictor model in arch surgery
4) to evaluate long-term survival outcomes and quality of life after aortic arch surgery.
