People with vascular problems may need a range of tests to help diagnose what is wrong.
This is likely also to involve taking various kinds of images of the arteries/veins to see if there are any blockages or areas where the wall has ballooned out.
Examples include ultrasound, CT (computerised tomography), MRA (magnetic resonance angiography), and conventional catheter-based angiography (imaging the blood vessels by injecting contrast fluid into them).
In addition, a blood test may be carried out to exclude other problems e.g. diabetes, high cholesterol, anaemia. Any one of these problems can contribute to or exist alongside vascular disease.
