[Surgical treatment of thoracic aortic disease combined with coronary artery bypass grafting operation].

We evaluated the early outcome of surgical treatment of thoracic aortic disease combined with coronary artery bypass grafting (CABG). Between January 2001 and December 2007, a total of 22 patients underwent thoracic aortic surgery with CABG. Four patients had an emergency operation performed for acute type A aortic dissection (group D). Three patients with a dissection of the right coronary artery (RCA) and 1 patient with cardiac ischemia during operation underwent CABG. One of the 18 patients with non-dissecting aneurysm (group N) underwent CABG due to injury of RCA. A comparative study was made between the study groups and a control group of 68 patients (group S) who underwent thoracic aortic replacement without CABG. Hospital mortality was 4.5% (1/22 patients) due to low output syndrome. There were significant differences in operation time, total cardiopulmonary bypass time and cardiac arrest time between groups D and N, and between groups N and S. There was also a significant difference in ventilation time and the duration of stay in the intensive care unit between groups D and N. However, there were no significant differences in postoperative complications among all the groups. This operation provides satisfactory early clinical outcomes. Thoracic aortic surgery combined with CABG can be carried out safely in elderly patients.
