 Rationale: The use of tissue pedicle and free tissue transfer flaps allows for increased reconstructive possibilities for patients that have had disfigurement or loss of function after trauma or oncological surgical resection. Generally, the process of creating a pedicle tissue transfer flap involves the isolation of tissues onto a single artery and vein and then rotating this tissue from the donor site to the site requiring reconstruction. A free tissue transfer flap involves a process similar to the creation of a pedicle flap except that the artery and vein going to the flaps tissues are divided and re-implanted at the site of reconstruction. This process of using tissue transfer flaps however has known complications, including acute complications such as arterial or venous occlusion and late complications such as the development of fat necrosis and flap atrophy.
