[Three-dimensional demonstration of the spinal cord artery with 64-row computed tomography].
This is a report of 2 cases, in which preoperative 3-dimentional demonstration of the spinal cord artery with 64-row computed tomography was feasible, less invasive, less time-consuming, and helpful in making an interventional strategy for complex aortic disease, resulting in no postoperative paraplegia One was a 63-year-old man, who underwent total arch replacement and a long elephant trunk method for arch and descending aortic aneurysms. The length of the long elephant trunk was so determined that it ended between the descending aortic aneurysm and the origin of the spinal cord artery. The second case was a 59-year-old man, who underwent descending thoracic aorta replacement for type B aortic dissection. During the distal anastomosis, the dissection septa were trimmed in order to perfuse the blood into the true and 2 false channels, one of which was connected to the spinal cord artery. In this report, we are not suggesting that preservation of the demonstrated spinal cord artery is enough for spinal cord protection, because it is still controversial. Further study is needed to confirm the reliability and reproducibility of our methods.
