Calciphylaxis. There are two components: first, your renal doctor will need to look into correctable biochemical abnormalities to see if there is something to be corrected like calcium, phosphate, and parathyroid hormone levels; second, the wounds will need careful treatment in a wound center by a physician that is willing to work with you over long term.
Underlying cause,HD. The patients who have had wounds with underlying calciphylaxis, they usually have severe pain, & not healing despite taking all conventional measures. Although it is uncommon I have treated several patients in recent months. We must exclude infection, optimize dialysis and other measures for calciphylaxis, while take "vigilant approach" for the wound care, avoid unnecessary debridement and ?Hbo.
Gentle treatment. Calciphylaxis is a very difficult wound but not impossible. First calcium and PTH must be regulated. The wound is very sensitive to trauma and debridement needs to be kept to a minimum. Great care in dressing choice must be taken to avoid any sticking. I use moist aquacell which i flush off with saline to change. There is limited evidence for hbot although its pathology makes it logical.
