What this trial studies

This clinical trial investigates the use of indocyanine green (ICG) angiography during total thyroidectomy to improve the detection of parathyroid glands and reduce the risk of postoperative hypoparathyroidism. Hypoparathyroidism is a common complication that can lead to significant quality of life deterioration if it becomes permanent. By utilizing ICG angiography, the study aims to enhance the preservation of parathyroid glands during surgery, potentially decreasing the incidence of this complication. The trial will compare outcomes between patients receiving ICG angiography and a control group.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the rates of postoperative hypoparathyroidism, improving patient outcomes and quality of life.

How similar studies have gone: Previous studies have shown promising results with the use of ICG angiography in similar surgical contexts, indicating potential for success in this approach.
