Comparison of sacrificed healthy aorta during thoracoabdominal aortic aneurysm repair using off-the-shelf endovascular branched devices and open surgery

摘要

Background: Off-the-shelf devices for branched endovascular aortic repair of thoracoabdominal aortic aneurysm (TAAA) have been developed to overcome the manufacturing-and logistics-related delays characteristic of device customization. Nonetheless, the structural requirements of branched endovascular aortic repair, together with the need for additional thoracic components to suit different anatomies, might lead to a large sacrifice of healthy aorta.
