[Subintimal angioplasty and diabetic foot revascularisation]

Diabetic wounds foot are responsible for 5-10% minor or major amputation in France. In fact, amputation risk of lower limbs is 15-30% higher for diabetic patients. University of Texas classification (UT) is the reference for diabetic foot wound. It distinguish non ischemic and ischemic wound with more amputation. If ischaemia is combined, revascularization may be considered for salvage of the limb. Some revascularization techniques are well known: as surgical by-pass, angioplasty with or without stent, or hybrid procedures with the both. Subintimal angioplasty is a more recent endovascular technique, in assessment for old patients who are believed to be unsuitable candidates for conventional by-pass or angioplasty.
