A Population-Based Study of the Incidence and Natural History of Degenerative Thoracic Aortic Aneurysms.

ABSTRACT:

Objective

To investigate the incidence and natural history of degenerative thoracic aortic aneurysms (TAAs) and compare results between ascending (aTAAs) and descending TAAs (dTAAs).

Patients and methods

This population-based cohort study used the Rochester Epidemiology Project database from January 1, 1995, through December 31, 2015. Patients were classified as the aTAA or dTAA group.

Results

Of 238 Olmsted County residents studied, 131 (55.0%) were women; 154 (64.7%) were in the aTAA group, and 84 (35.3%) were in the dTAA group. Median age was 77.0 years (interquartile range, 69.1-83.8 years). The overall age- and sex-adjusted incidence rate was 13.8 per 100,000 person-years (95% CI, 12.1 to 15.6) and varied from 9.9 in 1995 to 1999 to 19.0 in 2005 to 2009. It was 9
