Is hypothermia a reliable adjunct for spinal cord protection in descending and thoracoabdominal aortic repair with regional or systemic cooling?

摘要

Since DeBakey first carried out thoracoabdominal aortic repair with an aortic homograft using a temporary arterial shunt in 1956,' multidisciplinary approaches have been directed toward minimizing spinal cord isch-emic injury during surgery of the descending thoracic and thoracoabdominal aorta. The principal modality has been distal aortic perfusion during the aortic cross-clamping, which was passive in the past with a temporary shunt tube or bypass and that currently has been active with a left heart bypass or a cardiopulmonary bypass (CPB).
