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

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 (Division of Cardiovascular Surgery, Funabashi Municipal Medical Center, Funabashi, Japan) Kenji Mogi Yoshiharu Takahara Shigeyasu Takeuchi Manabu Sakurai 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 axillobifemoral 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.
