Conventional Method |
Naked eye view assessment of parathyroid gland after total thyroidectomy |
Intervention |
Indocyanine Green fluoroscence dye |
ICG will be prepared, according to protocol, the dye mixed with 5 ml sterile water and 2.5 ml injected intravenously. The injection repeated until a maximum dose of 5 mg per kg per day. The catheter flushed after each injection for a rapid image gain. After approximately 1–2min, images acquired using the SPY Fluorescent Imaging system (Novadaq, Ontario, Canada). This system consists of an imaging head equipped with a charge-coupled device camera, a laser light source, and a distance sensor. After thyroid resection, all identified parathyroid glands will be scored visually for viability from grade 0 (no vascularity) to 2 (excellent vascularity), and angiography with ICG will be then performed. The parathyroid glands will appeared in shades of grey depending on the amount of ICG flowing through the parathyroid tissue, thereby reflecting the degree of vascular blood flow |

Brief Summary
|
Identification of parathyroid
glands is one of the main concerns in thyroid surgery. It is usually very
difficult to distinguish parathyroid glands from thyroid and surrounding
tissues in the neck due to their small size and variable location. The
percentage of incidental parathyroidectomies is around 16% The incidence rate
of hypocalcemia can reach up to 4.5% in total thyroidectomies rising to 11.5%
in thyroidectomies with central node dissection. These rates can increase to
50% for transient hypocalcemia and 13.8% for permanent hypocalcemia in total
thyroidectomies. The main cause of hypocalcaemia after total thyroidectomy is
hypoparathyroidism due to intraoperative damage to the parathyroid glands by
trauma, inadvertent parathyroid gland removal or devascularization. The extent
of damage to the parathyroid glands is difficult to predict during surgery. The
feasibility of ICG in assessing the parathyroid gland function in patients
undergoing thyroidectomy and thereby preventing postoperative hypocalcemia is
being compared with our conventional methods in this study |
