[Individual temperature management during thoracoabdominal aortic aneurysm repair using separate perfusion of upper...

We report thoracoabdominal aortic aneurysm repair using separate perfusion of upper and lower torso that can control temperature of each organ individually. This novel modality can maintain mild hypothermic organ perfusion in upper torso and protect the heart under empty beating, while lower torso is further cooled to protect the spinal cord and visceral organs. Therefore this technique may be useful for patients with heart disease who require complex reconstruction of the intercostal arteries or visceral branches. We used this technique successfully in a patient who has a history of surgical repair of the aortic arch and the abdominal aorta. A 70-year-old male who had a history of abdominal aortic aneurysm repair and aortic arch aneurysm repair using stented elephant trunk underwent Crawford's type II thoracoabdominal aortic aneurysm repair. Three pairs of the intercostal arteries and 4 visceral branches were reconstructed using this technique successfully.
