Abstract:
The Open versus Endovascular Aneurysm Repair trial is the only randomized controlled trial that is funded by the federal government to evaluate the treatment outcomes of infrarenal abdominal aortic aneurysms. Since the initial publication, multiple post-hoc analyses have become available. This review summarizes these data, focusing on the primary outcome measures (ie, overall survival) and several key secondary outcomes including aneurysm-related death, age consideration, secondary procedures, and endoleaks. Cost-effectiveness of each treatment modality and the limitations of OVER trial also are discussed critically in this review.
