Evaluation of visible spinal arteries on computed tomography angiography before and after branched stent graft repair for thoracoabdominal aortic aneurysm

More spinal arteries are visible during the TASP interval, supporting the open branch and TASP concept with a reduction of severe SCI during BEVAR. An intentional coverage of more than 15 SAs is related to an increased risk of SCI, and the rate of paraplegia was reduced after staged BEVAR with open branch/TASP in these high-risk patients.
