ABSTRACT
A 69-year-old man was admitted for treatment of thoracic aneurysm. DSA revealed multiple aortic aneurysms: three true aneurysms which were located at the distal arch, the thoraco-abdominal aorta at the diaphragm level and the infrarenal abdominal aorta, 60mm, 55mm and 55mm in diameter, respectively and two pseudo-aneurysms which were located in the abdominal aorta just below the right renal artery and the right common iliac artery. We decided to perform a two-staged operation. Before the first operation, 1, 200ml of autologous blood was stored for perioperative blood transfusion. Initially, total arch replacement was performed using deep hypothermic circulatory arrest and antegrade selective cerebral perfusion. One month after the first operation, total thoraco-abdominal aorta replacement was performed by a retroperitoneal approach with mild hypothermia. The Th 9, 10 and 11 intercostal arteries were reconstructed. Distal anastomosis was performed at both common iliac arteries. Blood transfusion was not required for blood pooling and reduction of priming volume in the cardiopulmonary bypass system.
