In the case of a free tissue transfer flaps, the blood vessels to the transferred tissues are detached and then re-attached to different arteries veins at the recipient site. The process of reconstructive surgery using tissue transfer flaps allows for improved results in terms of functionality, aesthetic appearance, and psychological well-being in patients requiring reconstructive surgery after cancer resection or trauma.

These complications may include acute arterial or venous occlusion, as well as the development of late complications such as fat necrosis and flap atrophy.
