Microvascular free tissue transfers

Also known as: Free flap transfer, Free tissue transfer

The vascular detachment of a region of the body (eg, skin, fat, muscle, bone) followed by transfer of that tissue to another region of the body with reattachment of the artery and vein to a separate artery and vein. This ability to transplant living tissue from one region of the body to another enables reconstruction of complex defects.

Some of the advantages of free flap transfer include stable wound coverage, improved aesthetic and functional outcomes, and minimal donor site morbidity. The success rate for free tissue transfers among experienced surgeons is between 95-99%.
