Peripheral arterial disease (PAD) causes narrowing of the blood vessels, reducing blood flow to the lower limbs. Severely diminished blood flow causes constant leg pain day and night and is often accompanied by ulceration and gangrene. This stage is classed as Critical Limb Threatening Ischaemia (CLTI) and not only is there a threat of losing a limb, it carries with it the increased risk of stroke, heart attack and mortality.
Revascularisation surgery aims to increase blood flow, reduce pain and preserve the limb but what else can be done to improve patient outcomes?
