flap necrosis
Death of transplanted tissue due to inadequate blood supply in reconstructive surgery.
Full Definition
Flap necrosis represents the death of transferred tissue resulting from insufficient arterial inflow, inadequate venous drainage, or thrombotic events affecting the flap's vascular supply. This complication can range from superficial skin necrosis to complete flap loss, significantly impacting reconstructive outcomes and potentially requiring salvage procedures or alternative reconstruction methods. Risk factors include smoking, radiation therapy, diabetes, and technical factors such as vessel caliber mismatch or excessive tension on the vascular pedicle.
Usage
Usage note: Critical complication requiring immediate recognition and documentation in surgical records.
