Abstract OBJECTIVES: To investigate population trends in thoracic aortic disease (dissections and aneurysms) in England and Wales, with focus on the impact of thoracic endovascular aortic repair on procedure numbers and age at repair. MATERIALS AND METHODS: Routine hospital statistics of England and Wales provided admission, procedure and mortality data from 1999 to 2010. All data were age-standardised, reported per 100,000 population, by age bands (>50 years or 50-74 years versus 75+ years) and gender. Only patients 50+ years were included, to focus on degenerative disease. RESULTS: Between 1999 and 2010 hospital admissions for total (ascending and descending) have risen steadily for thoracic aortic dissection (TAD) from 7.2 to 8.8 and thoracic aortic aneurysm (TAA) from 4.4 to 9.0, principally attributable to increased admissions in those 75+ years. Total mortality declined steadily over the same period, for TAD from 4.4 to 3.2 and for TAA from 10.4 to 7.5. Procedure rates have risen sharply, driven by the implementation of TEVAR from 2006, for type B dissection from 0.06 to 0.53 and for descending TAA from 0.76 to 1.89. All figures are per 100,000 population with P <0.005. CONCLUSION: Improvements in case ascertainment may have contributed to the increase in hospital admissions. The increased application of TEVAR, particularly for dissections, is mainly in those above 75 years and has not yet translated into an accelerated survival benefit.
