Perioperative serum levels of procalcitonin, C-reactive protein, and leukocytes in head and neck free flaps

Microvascular free flaps are considered to be the gold standard in reconstructive head and neck surgery. However, reduced postoperative transplant perfusion is one of the serious postoperative complications and calls for close and reliable monitoring. Procalcitonin, C-reactive protein, and leukocytes are closely associated with local and systemic inflammatory reactions and might have prognostic capacity concerning tissue necrosis. This study aimed to evaluate perioperative serum levels of these three biomarkers to assess their potential in postoperative flap monitoring.
