Summary

Patients with a ruptured thoracic aortic aneursym experience among the highest rates of mortality reported for any cardiovascular condition. When repair is performed before rupture, these rates can be reduced from 48% to >19% at 30 days, and from 62% to >31% through 365 days. In both situations, however, the increasing mortality after 30 days demonstrates a significant risk that extends beyond the initial perioperative period. This article discusses the techniques used to minimize the risk of endoleaks in patients being treated for aortic aneurysms with endovascular techniques.
