flap necrosis
Pronunciation: nek-ROH-sis
Death of tissue in a surgical flap due to inadequate blood supply.
Full Definition
Flap necrosis refers to tissue death within a surgically created or transferred flap due to compromised blood supply. This complication can result from various factors including inadequate vascular supply, excessive tension on the flap, hematoma formation, infection, or patient-related factors such as smoking or poor circulation. Necrosis may be partial (affecting only superficial layers) or full-thickness, and can occur immediately post-operatively or develop days to weeks after surgery. Early recognition is crucial as salvage procedures may be possible if vascular compromise is identified quickly. Prevention strategies include careful surgical planning, tension-free closures, and optimization of patient factors.
Usage
Usage note: Specify degree (partial vs. full-thickness) and location when documenting flap necrosis.
