Conclusions
 Both open and hybrid operations in the thoracoabdominal
aorta remain extremelly complex operations
 The results of open repair of TAAA have improved
significantly over the last decade in centers of excellence
 The long term outcomes of hybrid operations have not
been determined yet.
 Open TAA repair remains the procedure of choice in
appropriately selected candidates

Questions
 Does endovascular surgery treat the same patients
as open surgery ?
 Does endovascular surgery treat the same extent of
aorta?
 Does endovascular surgery deliver the same long-
term outcomes?

Operative Management
Lenox Hill Heart and Vascular
Institute of New York
 Is it reasonable to search for a single segmental
artery whose preservation will prevent paraplegia?
NO
 Is it reasonable to monitor spinal cord integrity in
the perioperative period and treat cord ischemia
when it occurs? YES
 Do we yet have a strategy to assure preservation of
spinal cord integrity through the perioperative
period of thoracic and thoracoabdominal aortic
aneurysm resection? NO
 Has the neurological outcome of thoracic and
thoracoabdominal aortic surgery improved
markedly in the past decade? YES
