Comparative Study Observational Study
Anemia and postoperative outcomes after open and endovascular repair of intact abdominal aortic aneurysms.
Anemia is associated with increased cardiac adverse events during the early postoperative period because of high physiologic stress and increased cardiac demand. The aim of this study was to assess the surgical outcomes and prognostic implications of anemia in patients undergoing repair of intact abdominal aortic aneurysms (AAAs). ⋯ Preoperative anemia is associated with higher odds of 30-day mortality and in-hospital adverse outcomes after EVAR but not after OAR. These findings highlight the need to incorporate anemia into the preoperative risk assessment of patients undergoing EVAR. Future studies are needed to assess the efficacy of medical therapies in improving postoperative outcomes in anemic patients undergoing AAA repair.

An anatomic severity grade (ASG) score to categorize and to define anatomic factors for abdominal aortic aneurysm (AAA) repair was proposed. Other studies have previously reported that aortic anatomic complexity is a marker of survival and resource utilization after repair, although it remains unclear whether individual components of the ASG score independently contribute to survival. This study analyzed and validated an aortic and iliac artery calcium scoring system that can potentially predict survival after AAA repair. ⋯ A CS ≥3 is linked to a lower 5-year survival after AAA repair in our population. This system potentially can be another measure for risk stratification and serve as a means to predict midterm mortality in AAA repairs. Future study will be needed for further validation to predict midterm mortality and to better guide surgical decision-making.
