Episode description
A 70 year old healthy female is referred to you with a 5.7 cm abdominal aortic aneurysm. As an astute clinician you are aware that current guidelines support surgical repair for her AAA. What if there was new data to suggest this patient may not benefit from repair? What would be the optimal size threshold that she would benefit from AAA repair? Tune into this episode of Behind the Knife, where the vascular surgery subspecialty team discusses a paper that challenges current size threshold guidelines for AAA repair.Hosts:
Dr. Bobby Beaulieu is an Assistant Professor of Vascular Surgery at the University of Michigan and the Program Director of the Integrated Vascular Surgery Residency Program as well as the Vascular Surgery Fellowship Program at the University of Michigan.
Dr. Frank Davis is an Assistant Professor of Vascular Surgery at the University of Michigan
Dr. Drew Braet is a PGY-5 Integrated Vascular Surgery Resident at the University of Michigan
Learning Objectives
- Review the current size threshold guidelines for surgical repair of abdominal aortic aneurysms
- Understand the limitations of the aforementioned guidelines
- Understand the methodology, findings, limitations, and clinical applications of the manuscript “Size thresholds for repair of abdominal aortic aneurysms warrant reconsideration.”
