National temporal trends and determinants of cost of abdominal aortic aneurysm repair.

Introduction: In recent decades, there has been a shift in the management of aortic abdominal aneurysm from open intervention (open aortic aneurysm repair) to an endovascular approach (endovascular aortic aneurysm repair). This shift has yielded clinical as well as socioeconomic reverberations. In our current study, we aim to analyze these effects brought about by the switch to endovascular treatment and to scrutinize the determinants of cost variations between the two treatment modalities.
