Autofluorescence in Surgery for Primary Hyperparathyroidism

In the experimental group, the surgeon will use the EleVision IR camera system (Medtronic, USA) to visualize PTGs during surgery. The surgical field will be visualized with AF as a minimum of two times during surgery on each side of the neck: First upon exposing the undersurface of the thyroid gland, and secondly before removal of a pathological PTG. Also, removed PTGs will be examined ex vivo to document AF pattern.
