Vascular Current Research

The Vascular Research team conducts research that aims to improve the care of men and women using vascular services department at NBT. This includes arterial surgery, diabetic foot care, leg ulcers, varicose veins, and other vascular diseases.

We have had a successful research team in place for several years delivering complex interventional and observational studies.

The team collaborates widely with other disciplines and professions to develop ground-breaking research and care, for our patients and throughout the NHS.

Please speak to the person treating you to see if there is a research study that may be able to help you.
