tissue necrosis
Pronunciation: TISH-oo neh-KROH-sis
Death of tissue cells or tissue sections due to inadequate blood supply, infection, or other pathological processes affecting surgical outcomes.
Full Definition
Tissue necrosis refers to the pathological death of cells and tissues, representing a significant complication in plastic and reconstructive surgery. In surgical contexts, necrosis most commonly results from compromised vascular supply, excessive tension on tissues, infection, or thermal injury. The extent of necrosis can range from superficial skin loss to full-thickness involvement affecting deeper structures. Early recognition is crucial as necrotic tissue must be debrided to prevent infection and promote healing. Risk factors include smoking, diabetes, previous radiation, and excessive surgical tension. Management involves wound care, debridement of nonviable tissue, and often secondary reconstruction procedures. Prevention strategies focus on maintaining adequate tissue perfusion and minimizing tension in closures.
Usage
Usage note: Document extent, depth, and suspected etiology when recording tissue necrosis.
In Context
- "Partial tissue necrosis at the incision edges required surgical debridement and delayed closure." — Complication report
- "The patient's smoking history placed her at increased risk for tissue necrosis following the flap procedure." — Pre-operative counseling note
