tissue perfusion
Adequate blood flow to tissues, critical for flap and graft survival in reconstructive surgery.
Full Definition
Tissue perfusion refers to the delivery of oxygenated blood to tissues at the cellular level, which is fundamental to the success of all plastic surgery procedures, particularly flaps and grafts. Assessment of perfusion involves evaluating capillary refill, color, temperature, and bleeding patterns. Compromised perfusion can lead to tissue necrosis, flap failure, or graft loss. Surgeons must carefully consider factors affecting perfusion including surgical technique, positioning, pressure points, and systemic conditions when planning and executing reconstructive procedures.
Usage
Usage note: Broader concept than simple vascular patency; encompasses microcirculation and cellular oxygen delivery.
