![]() Whether or not AAI involvement impacts other measures of morbidity such as freedom from operation or endovascular intervention deserves further study.Īcute aortic dissection is a life-threatening cardiovascular disease associated with considerable morbidity and mortality. AAI was not an independent predictor of long-term mortality.Ĭonclusions- Patients with TB-AAD and aortic arch involvement do not differ with regards to mortality at 3 years. Mortality for patients without AAI was 9.4%±4.3% and 21.0%☖.9% at 1 and 3 years versus 9.2%☗.7% and 19.9%☑1.1% with AAI, respectively (mean follow-up overall, 2.3 years, log rank P=0.82). Independent predictors of AAI were a history of previous aortic surgery (OR 3.4 95% CI, 1.6 to 7.6 P=0.002), absence of back pain (OR 1.6 95% CI, 1.1 to 2.5 P=0.05), and any pulse deficit (1.9 95% CI, 1.1 to 3.3, P=0.03). We found that 371 (74.5%) patients with TB-AAD did not have AAI versus 127 (25.5%) with AAI. Kaplan-Meier mortality curves were constructed and multivariate regression models were performed to identify independent predictors of AAI and to evaluate whether AAI was an independent predictor of follow-up mortality. Methods and Results- We examined 498 patients with TB-AAD enrolled in the International Registry of Acute Aortic Dissection (IRAD) between 19. However, the treatment of TB-AAD with aortic arch involvement (AAI) remains an unresolved issue.
