During the recent decades, soaring progresses in vascular disease knowledge, particularly in critical limb ischemia (CLI) treatment, enhanced novel diagnostic and interventional strategies with high serviceableness in patient's selection, arterial recanalization, and dedicated ischemic ulcer follow-up. However, despite undeniable advances in medical technology and clinical judgment, limb salvage, the ambulation recovery, and patient's survival seem only scarcely affected in this heterogeneous CLI group, particularly concerning the diabetic and renal patients. Innovative strategies such as "end artery occlusive disease" treatment or "wound-targeted revascularization" were equally proposed by following the angiosomal anatomical distribution associating individual foot collateral assessment in a unified macro-and micro-circulatory judgment. However, despite encouraging clinical results, prospective evidence still lacks on this concern. It also appears that specific wounds could not always stand for the lowest perfusion areas according to current CLI criteria, since severe neuropathy, inflammatory swelling, local infection, and skin trauma may add complementary hindrances to tissue viability.The present chapter endeavor to summarize main available treatment principles for ischemic ulcer recovery that every modern practitioner eventually disposes in an updated contemporary view."
