Glow-in-the-dark dye could help surgeons save tiny glands during thyroid surgery
NCT ID NCT06169735
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a fluorescent dye called indocyanine green can help surgeons find and protect the parathyroid glands during thyroid or parathyroid surgery. The dye is injected into the bloodstream and makes the glands glow under a special camera. The trial enrolled 417 adults but was terminated early, so the full results are not available.
