About

Indocyanine green (ICG) is a water-soluble organic dye that is cleared totally through the hepatobiliary system. It has a half-life of 3-4 mins, which allows repeated applications. Near-infrared (NIR) fluorescence imaging with indocyanine green (ICG) imaging has been recently introduced, and has been suggested as a useful tool for the identification and preservation of the parathyroid glands (PGs) during total thyroidectomy (TT). ICG can also be used for sentinel lymph node (SLN) biopsy to predict the micrometastases in central lymph nodes (CLN) in thyroid carcinoma, and central lymph node dissection can reduce local recurrence.

Full description

Incidence of thyroid cancer has doubled between 1980 and 2020, and it is now the fifth most common malignant tumor among women. The majority are papillary thyroid cancer (PTC), and TT is the procedure of choice. Since the micrometastasis rate of the central lymph nodes (CLNs) is about 30% to 90% in PTC, CLN dissection can improve the prognosis and reduce tumor recurrence as well as provide accurate information for the evaluation of tumor staging. However, TT procedure has some important complications such as vocal cord paralysis (VCP) and hypocalcemia (due to accicental parathyroidectomy or damage to the parathyroid gland-PG- vasculature). Use of intraoperative nerve monitoring (IONM) has reduced the rate of VCP. However, the incidence of postoperative hypocalcemia is still high (15-70%), and it is now the most common complication of TT. Intraoperative identification of SLNs and PGs can help surgeon to overcome these problems.
