free flap
Tissue transfer involving complete detachment and microvascular reanastomosis at the recipient site.
Full Definition
A free flap is a segment of tissue completely detached from its blood supply and transferred to a distant location with microsurgical reconnection of arteries and veins. This technique allows reconstruction of complex defects with healthy, well-vascularized tissue. Common free flaps include fibula flap for mandible reconstruction, anterolateral thigh flap for soft tissue coverage, and DIEP flap for breast reconstruction. Success depends on surgical technique, patient factors, and postoperative monitoring for vascular compromise. Flap monitoring protocols include clinical assessment, Doppler ultrasound, and sometimes implantable monitors.
Usage
Usage note: Always specify the type of free flap and include details about vascular anastomosis in operative reports.
