Abstract
Blood perfusion as the supply of tissue with blood and therefore oxygen is a key factor in clinical practice. Especially in the field of flap surgery, a reduced perfusion of transplanted skin or operated areas is often cause of various complications. The success of microvascular reconstructions is directly related to the flap perfusion. The intraoperative and postoperative assessment of the anastomoses is of great importance in order to recognize possible complications at an early stage and to revise them in good time. Is the affected tissue located on the face, successful treatment and rapid healing is even more important since aesthetic aspects play a not insignificant role. A poor perfusion is often concealed, since methods are missing for an objective assessment of the perfusion status. A method with increasing importance for clinical practice is given by hyperspectral imaging. We developed a new hyperspectral imaging system that can be used to observe tissue oxygenation and other tissue parameters and present the technical background and the parameter validation.
