A Case of Ruptured Thoracoabdominal Aortic Aneurysm Repair under Profound Hypothermia Using Subclavian Arterial Perfusion through Right Axillo-Bifemoral Bypass Graft Implanted Ten Years Previously / 日本心臓血管外科学会雑誌

ABSTRACT

A 74-year-old woman had undergone right axillo-bifemoral bypass for infrarenal aortic stenosis due to aortitis syndrome in another hospital. She was admitted as an emergency case to our hospital with a ruptured thoracoabdominal aortic aneurysm, and an emergency operation was performed. We used arterial cannulation to the artificial vascular graft implanted for axillo-bifemoral bypass and first cooled the body temperature to below 25°C, then dissected the aorta. In the case of ruptured descending and thoracoabdominal aortic aneurysm, profound hypothermia is a valuable adjunct for unexpected blowout rupture during the preparation of the aneurysm and spinal cord and visceral protection.
