Paper Abstract

Skin grafts and flaps form the basis of plastic and reconstructive surgery. Transplanted tissue such as a skin graft or free flap can experience a range of perfusion related complications. A number of adjunctive monitoring techniques have been suggested, however, none have met with clinical acceptance. A simple optical spectroscopic method is investigated and is shown to be superior to blood flow based methods for detecting and distinguishing between arterial insufficency and venous congestion in free flaps. The work suggests that this simple method may have clinical utility.
