Clinical Description: Abdominal aortic aneurysm repair is a surgical procedure involving the correction or reinforcement of a weakened or bulging segment of the abdominal aorta, a major blood vessel. This procedure is performed to prevent the risk of aneurysm rupture, which can be life-threatening, by either surgically excising the aneurysm and replacing it with a graft (open surgery) or by using minimally invasive techniques to insert a stent graft to reinforce the weakened area (endovascular repair). The logic in this definition aims to select for a cohort undergoing non emergent procedures. Further details to aid in the population level evaluation of this cohort will be posted to this thread.
Evaluation Conclusion: Pending
