Outcome prediction in microsurgery by quantitative evaluation of perfusion using ICG fluorescence angiography.

The purpose of this prospective study was to evaluate the clinical efficacy of laser-induced fluorescence angiography with indocyanine green (ICG-FA) for perioperative monitoring of tissue perfusion in hand surgery. Different quantitative parameters of the uptake, distribution and clearance of dye-marked blood were evaluated for their sensitivity and prognostic value in comparison to each other and to clinical parameters. One hundred and fifty-five measurements were performed prior to, or following, surgery for severe hand injuries.
