Angiosome is derieved from the anatomy concept of multiple areas of the body supplied by individual blood vessels and hence blockages of those vessels leading to death of the areas supplied by them.
However the body has a vast network of vessels and collateral circulation takes care of blood supply upto a certain extent. With large wounds and extensive infection (especially in diabetics) , more blood is needed to heal the wounds. Hence angiosomal circulation to particular areas need to be improved.
The issue with multiple cooks (specialists) : with separate doctors for blood supply improvement, wound management and wound healing, most wounds end up with major amputations and long followup periods. A Vascular and Endovascular Surgeon can bridge this divide with ability to vascularize both by open and endovascular methods, wound care, debridement and essentially heal the wound at an earlier stage mostly avoiding major amputations or limb loss.
