Comparative Study
Epidural cooling for spinal cord protection during thoracoabdominal aneurysm repair: A five-year experience.
We developed and applied a method for providing regional spinal cord hypothermia with epidural cooling (EC) during thoracoabdominal aneurysm (TAA) repair. Preliminary results indicated significant reduction in spinal cord ischemic complications (SCI), compared with historical controls, and a 5-year experience with EC was reviewed. ⋯ EC has been effective in reducing immediate, devastating, total paraplegia after TAA repair. A strategy that combines the neuroprotective effect of regional cord hypothermia, avoiding the sacrifice of potential spinal cord blood supply, and postoperative adjuncts (eg, avoidance of hypotension, CSF drainage) appears necessary to minimize SCI after TAA repair.

Aortobifemoral bypass grafting is a durable operation for arterial reconstruction in patients with symptomatic aortoiliac occlusive disease. In several small laparoscopic series technically demanding aortic operations have been described that have not gained widespread acceptance or applicability. To simplify the laparoscopic approach to the aorta, we have developed a technique of aortobifemoral bypass grafting that uses hand-assisted laparoscopic surgery (HALS) to minimize the complexity of aortic dissection and reconstruction. ⋯ The HALS offers the advantages of tactile feedback, flexible retraction, and the introduction of conventional surgical instruments, all of which extend laparoscopic surgery and its established benefits to a wide array of more complex surgical problems, including major vascular surgery. Ease of performance, shorter hospital stays, and faster recovery times all suggest that HALS may become a valuable adjunct to conventional aortobifemoral bypass grafting.
