Near Infrared Autofluorescence Imaging in Minimally-Invasive Video-Assisted Parathyroidectomy (NIRAF MIVAP Study)

"The FLUOBEAM® LX apparatus consists of a camera with a built-in light emitter (750-800 nm) and detector (800-830 nm) connected to a processor with an indication-oriented software (Fluosoft®). The processor captures the emitted light, allowing display of PTG images in real time. The camera is placed in a sterile sheath and is held perpendicularly at 8 cm from the target tissue with operating lights, all background lights, and any ambient light being extinguished. The reported depth of tissue penetration of near-infrared light is limited to a maximum of 3 mm only with no observed differences between superior and inferior PTGs \[10\]. This highlights the importance of a major surgical technical point reaching the correct plane of dissection namely, the pre-vertebral fascia to maximize the chances of eliciting an adequate signal from parathyroid tissue. The correct application of the technology has demonstrated a success rate of signal elicitation of 90%-100% \[11\]. The ability of near-infr"
