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

The use of the t-Branch device compared with open repair is associated with a greater sacrifice of healthy aorta in extent IV TAAA and with an increased loss of intercostal arteries arising from healthy aortic proximal neck. The theoretical possible increased risk of spinal cord ischemia secondary to the routine use of this off-the-shelf device should thus be analyzed further.
