Surgical Results of Descending Thoracic and Thoracoabdominal Aortic Aneurysm Repair Using deep Hypothermic Circulatory Arrest
Background: To avoid thromboembolism and aortic wall injury of the clamp site, open proximal and/or distal anastomosis technique with deep hypothermic circulatory arrest (DHCA) has been positively applied for complex descending thoracic and thoracoabdominal aortic aneurysm repair in our institution. We examined early surgical results of 161 patients underwent descending thoracic and thoracoabdominal aortic aneurysm repair applying this technique.
Methods: Since October 1992, 161 (121 men, age 62.3 ± 13.3 years) of 239 patients underwent descending thoracic and thoracoabdominal aortic aneurysm repair applied DHCA (67.4 %). The etiology of aneurysm included degenerative (n = 94), dissection (n = 53), trauma (n = 9), and others (n = 4). Emergent surgery was performed in 41 patients (25.5 %).
