Mean growth rate of popliteal aneurysms on U/S, by Sandra Piatkowska.

5 year retrospective local data set analysis

Gloucestershire

0.1-3% of adults affected by Pop AA

Mostly men

There is currently no consensus on optimal Pop AA surveillance interval or threshold

Locally it is set by consultant on a pt to pt basis

Consideration of cost effectiveness vs patient risk

Primary aim of the study:

Local average growth rate over the past 5 years

Secondary aim:

Identify factors that affect growth rate: Having a concurrent AAA, HTN, DM, Smoking, Statins and anti-thrombotic meds

Going to have inclusion criteria as minimum 2 scans

Methods of analysis will be

linear regressin for local growth rate and linear multiregression for individual patient growth rate

Audience suggestion: use logarithmic scale analysis because bigger they get faster they grow
