This study examined trends in abdominal aortic aneurysm incidence and mortality in New Zealand and compared these with mortality rates from England and Wales.Abstract:
Background:
This study examined trends in abdominal aortic aneurysm (AAA) incidence and mortality in New Zealand (NZ) and compared these with mortality rates from England and Wales.
Methods:
Cause-specific death data were obtained from the NZ Ministry of Health, UK Office for National Statistics and National Archives (for England and Wales). The NZ National Minimum Data Set provided hospital discharge data from July 1994 to June 2009.
Results:
In 2005–2007 the age-standardized AAA mortality rate for men was 33·3 per cent less in NZ than in England and Wales (5·21 versus 7·81 per 100 000), whereas for women it was 9·8 per cent less (2·12 versus 2·35 per 100 000). Standardized mortality rates in NZ fell by 53·0 per cent for men and 34·1 per cent for women from 1991 to 2007. Between 1991–1992 and 2005–2007 the probability of a 65-year-old dying from an AAA fell by 28·2 per cent (from 1·872 to 1·344 per cent) in men, and by 6·3 per cent (from 0·837 to 0·784 per cent) in women. New AAA admission and hospital death rates in NZ peaked in 1999 for men, and in 2001 for women, and have since declined sharply. Hospital mortality ratios have also fallen, except for women with a ruptured aneurysm.
Conclusion:
The burden of AAA disease has been falling since at least 1991 in NZ, and since 1995 in England and Wales. Although survival appears to be improving, most of the reduction is due to lower disease incidence. Copyright © 2011 British Journal of Surgery Society Ltd.

TL;DR: In this article, the authors prospectively determined incidence and outcomes of all acute aortic dissections in a population of 92 728 in Oxfordshire, United Kingdom, from 2002 to 2012.

Meta-analysis of individual patient data to examine factors affecting growth and rupture of small abdominal aortic aneurysms
TL;DR: Surveillance is a common management strategy for small abdominal aortic aneurysm (AAA) (3·0–5·4 cm in diameter) because individual characteristics, other than diameter, may influence aneurYSm growth or rupture rates.

Systematic review and meta-analysis of the growth and rupture rates of small abdominal aortic aneurysms: implications for surveillance intervals and their cost-effectiveness

TL;DR: Surveillance intervals of several years are clinically acceptable for men with AAAs in the range 3.0-4.0 cm, and future work should focus on optimising surveillance intervals for women, studying whether or not the threshold for surgery should depend on patient characteristics, and evaluating the usefulness of surveillance for those with aortic diameters of 2.5-2.9 cm.

Aneurysm Global Epidemiology Study Public Health Measures Can Further Reduce Abdominal Aortic Aneurysm Mortality

TL;DR: Investigating global AAA mortality trends reveals that differences between nations can be explained by variations in traditional cardiovascular risk factors, and a novel obesity paradox has been identified that requires further investigation.

Age standardization of rates: a new who standard

TL;DR: The World Health Organization (WHO) adopted a standard based on the average age-structure of those populations to be compared (the world) over the likely period of time that a new standard will be used (some 25-30 years), using the latest UN assessment for 1998 (UN Population Division, 1998) from these estimates, an average world population agestructure was constructed for the period 2000-2025 as discussed by the authors.

Endovascular versus open repair of abdominal aortic aneurysm.
TL;DR: Endovascular repair was associated with increased rates of graft-related complications and reinterventions and was more costly than open surgical repair, but no differences were seen in total mortality or aneurysm-related mortality in the long term.

TL;DR: Endovascular and open repair of abdominal aortic aneurysm resulted in similar rates of survival six years after randomization, and the rate of secondary interventions was significantly higher for endovascular repair.
