The following form calculates the expected mortality risk associated with abdominal aortic aneurysm repair using the peri-operative AAA SCORE. It uses automatic defaults for missing values and re-calculates each time a value is modified.

A full description of the model and its development can be found in Ambler et al. (2015): J Vasc Surg 61(1):35-43.
