Surgical management of pain or infection secondary to calciphylaxis: a wound center's experience and algorithmic...

The role of surgical management of calciphylaxis remains understudied.

This article reports a case series and algorithmic approach to the multidisciplinary management of calciphylaxis.

A single-center retrospective review of all adult patients with calciphylaxis treated surgically between January 2010 and November 2022 was performed.

Eleven patients met inclusion criteria. The average age was 50.9 years ± 15.8 SD, and most patients were female (n = 7 [63.6%]). Surgery was indicated for infection (n = 6 [54.5%]) and/or intractable pain (n = 11 [100%]). Patients underwent an average of 2.9 excisional debridements during their hospital course. Following the final excision, wounds were left open in 5 cases (29.4%), closed primarily in 4 (23.5%), and local flaps were used in 3 (27.3%). Postoperatively, the mean time to healing was 57.4 days ± 12.6. Complications included dehiscence (n = 1 [9.1%]), progression to cellulitis (n = 2 [18.2%]), osteomyelitis (n = 1 [9.1%]), and lower extremity amputation (n = 2 [18.2%]). Of the 6 patients alive at the time of healing, 5 (83.3%) were no longer taking narcotic medications. At an average follow-up of 26.4 months ± 34.1, 7 patients (63.6%) were deceased, with an average time to mortality of 4.8 months ± 6.7. Of the 4 remaining patients, 3 (75.0%) were ambulatory by their most recent follow-up visit.

While the morbidity and mortality associated with calciphylaxis are substantial, surgical excision is effective in reducing pain and improving quality of life in patients with this end-stage disease. Wound care centers are uniquely equipped with a variety of medical and surgical specialists with experience in treating chronic wounds and thus facilitate an efficient multidisciplinary model.
