BackgroundThe objective of this study was to determine the likelihood of mortality after abdominal aortic aneurysm (AAA) repair in patients with thoracic or thoracoabdominal aortic dissection.MethodsFourteen patients (11 men, three women) with known thoracic or thoracoabdominal aortic dissections underwent elective AAA repair from 1986 to 2001, including three patients with acute dissections (less than 14 days) and 11 patients with chronic dissections (14 days or longer). All 14 patients had type III aortic dissections. Stent graft exclusion of the aortic dissection was performed in one patient before AAA repair. Preoperative patient characteristics, intraoperative events, perioperative complications, and 30-day and 1-year mortality rates were assessed.ResultsElective AAA repair in the setting of thoracic or thoracoabdominal aortic dissection in this series was associated with no 30-day mortality and a 1-year mortality rate of 7.1%. Furthermore, preoperative patient characteristics, intraoperative events, and perioperative complications did not appear to be associated with late, 1-year, mortality.ConclusionElective AAA repair in the setting of acute or chronic aortic dissection is associated with mortality rates similar to those generally attributed to elective AAA repair without accompanying aortic dissection. Nevertheless, the conduct of the operation is usually complex, especially in the setting of an acute aortic dissection.
