The surgical treatment of a thoracoabdominal aortic aneurysm with total preservation of the intercostal and lumbar arteries using a permanent bypass technique--a case report.

A 44 year old man underwent successful surgery for a thoracoabdominal aortic aneurysm using a permanent bypass graft and aneurysmoplasty. This technique reduces visceral ischemia to a minimum and the aneurysmoplasty, through total preservation of the intercostal and lumbar arteries, can avoid paraplegia caused by spinal cord ischemia. Our technique is recommended as it can be performed easily, safely, and effectively without heparinization, temporary shunts or bypass perfusion.
