Tissue transfer flaps are a method of moving tissue from a donor location to a recipient location. 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 and veins at the recipient site. The process of reconstructive surgery using tissue transfer flaps is not without complications. These complications may include acute arterial or venous occlusion, as well as the development of late complications such as fat necrosis and flap atrophy.

Primary Outcome Measures:
  • Transfer Skin flap [ Time Frame: up to 6 weeks ]

Estimated Enrollment: 200
Study Start Date: January 2007
Estimated Study Completion Date: June 2018
Estimated Primary Completion Date: June 2018 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Tissue transfer skin flap
Modulated Imaging Spectroscopy
Device: Modulated Imaging
Modulated Imaging Spectroscopy

Detailed Description:
The researchers developed a safe, non-contact, intra-operative and post-operative device called Modulated Imaging, can detect changes in a flap's optical properties and can correlate with arterial or venous occlusion or with the development of fat necrosis or flap atrophy.
