Calciphylaxis-induced chronic wounds are difficult to heal. The value of vacuum-assisted closure (VAC) was assessed in two patients with calciphylaxis. Two middle-aged females with type 2 diabetes were transferred to the burn unit with a clinical diagnosis of necrotizing fasciitis, although the pathologic diagnosis was calciphylaxis. With extensive debridement, antibiotics, and meticulous wound care, one patient had progressive necrosis of her skin from 18 to 48% TBSA, whereas the other progressed from 5 to 10% TBSA only. The patient with the smaller chronic wound healed well and left the hospital at 72 days after admission. Although there was some success with the use of VAC, the patient with the extensive progressive wounds developed a fungal wound infection that did not respond to treatment; she died 78 days after initiation of burn center treatment. Some disadvantages to the usefulness would be extensive contiguous wounds and the lack of an intact skin surface. The VAC system was of value in healing wounds resulting from calciphylaxis.
