In treating arterial ulcers it should be remembered that not all foot sectors share same ischemic affectation and that not all patients with comparable *macro*-vascular images bear same collateral reserve and related *micro*-vascular tissue recovery resources.

Contemporary research reveals astonishing multilevel anatomical and physiological intricacy of lower limb blood supply, viewed in a dynamic and time unfolding perspective. This apparent complexity represents but plausible challenges for the experienced interventionist availing high-performance macro and microcirculatory diagnostic and treatment methods for revascularization and tissue healing.
