Abstract:
A 51-year-old man required replacement of the thoracoabdominal aorta due to a type II thoracoabdominal aortic aneurysm. We tailored and plicated the aortic aneurysm to make a closed tube. All of the intercostal arteries and lumbar arteries were reimplanted using a closed tube constructed with an aneurysmoplasty to the main aortic graft, using this tube to protect the spinal cord. The closed tube maintained blood flow to the intercostal and lumbar arteries, and no neurologic deficits developed.
