Open and Endovascular Management of Aortic Aneurysms.

Aneurysmal disease can affect any segment of the aorta, from the aortic root to the aortic bifurcation. The treatment of aortic aneurysms has evolved dramatically in the past 3 decades, with the introduction of endovascular aneurysm repair using stent grafts causing a major paradigm shift in the field of aortic aneurysm surgery. While the technical details of the management of aortic aneurysms vary greatly depending on the location of an aneurysm, the principles remain the same. Successful aortic aneurysm treatment depends on either open replacement or endovascular exclusion of the aneurysmal segment with healthy artery proximal and distal to the repair. Major aortic branches of the arch and visceral segment add additional technical complexity to aneurysms involving these regions. Even as endovascular repair becomes the primary treatment modality for most aortic aneurysms, open repair remains an essential treatment modality in many circumstances. Additionally, long-term results of endovascular repair suggest that younger patients with long life expectancy and low-perioperative risk may benefit more from open repair. Therefore, technical expertise in both endovascular and open treatment is necessary for a comprehensive aortic aneurysm surgery practice.
