An abdominal aortic aneurysm (AAA) is a swelling in the aorta, the main artery that carries blood from the heart through the tummy. Most do not cause problems, but a large aneurysm can burst, which is a life-threatening emergency. Men are offered an ultrasound screening test when they turn 65.
A large aneurysm may be repaired with a planned operation, either open surgery or a stent inserted through the arteries in the groin (endovascular repair). The National Vascular Registry publishes the number of planned repairs at each trust and deaths in hospital afterwards, adjusted for differences between patients. Call 999 for sudden, severe pain in the tummy or back.

How to read this
- Not a ranking. The table is in alphabetical order. A higher volume does not on its own mean better care, and we do not combine the columns into a score.
- Volume bands. Cut points are the lower quartile, median and upper quartile of all 64 trusts and health boards in the NVR table in the published table, rounded. So about a quarter of trusts and health boards in the NVR table fall in each band. The exact number is shown under the band.
- Risk adjustment. Where a figure says “adjusted”, the audit has allowed for differences in the patients each hospital treats, such as age and other illnesses. Hospitals that take on more complex cases can still look different for reasons the adjustment does not capture.
- Bands and limits. We only say a result is higher or lower than expected when the source itself says so (for example NJR outlier status, NELA funnel limits, SSNAP levels, CQC survey bands). Where the source publishes a rate without limits we show the rate and the national figure, and say “No banding published”.
- Small numbers. A small hospital can have 0% or a high percentage by chance. Figures the source suppresses are shown as “Not published (small numbers)”.
- Trust or hospital. This audit publishes figures for each NHS trust, which may run several hospitals. The operation may only be done at one of them.
- Different periods. Each figure has its own period, shown next to it. Audit results describe operations done one to three years ago; waiting times are updated monthly.
- National figures. National figure: England row of the NVR appendix tables.
- Talk to your GP or consultant about what the figures mean for you. If you are referred for planned care in England, you can usually choose your hospital.
