Calciphylaxis following coronary artery bypass surgery: an underappreciated cause of wound complications?

Wound complications following cardiac surgery are typically infectious and associated with a high morbidity and mortality. Calciphylaxis, vascular calcification of small and medium sized vessels, often associated with end-stage renal disease, can result in extensive tissue necrosis. We hypothesize that calciphylaxis is an under-recognized and under-reported precipitating wound and breast complication following coronary artery bypass surgery and thereby necessitates further study.
