Abstract
Introduction

Indocyanine green (ICG) angiography of the parathyroids is useful in prediction of postthyroidectomy hypocalcemia. We compared the diagnostic accuracy of a single-gland ICG score of 2 with a score estimated by adding the viability value of the four glands (4-ICG).

Methods

Fifty patients (66% women, median age 49.4 years) underwent total thyroidectomy with identification of all 4 glands. The degree of ICG was classified as 0, black (nonvascularized), 1, gray/heterogeneous (partially vascularized), and 2, white (well vascularized).

Results

The diagnostic accuracy of the optimal cut-off of the 4-ICG sum score ≤3 was 84% (95% CI 70.9–92.8) lower than the diagnostic accuracy of 92% (80.8–97.8) of the ICG score 2. Both scores identified 2 false negative cases, but the rates of false positives were lower with the ICG score 2 (18.2% vs. 57.1%).

Conclusions

Identification of single-gland ICG score of 2 has a higher diagnostic accuracy than 4-ICG sum score to predict immediate hypocalcemia after total thyroidectomy.

Resumen
Introducción

La angiografía de las glándulas paratiroides con verde de indocianina (ICG) es útil para predecir la hipocalcemia post-tiroidectomía. En este estudio se ha comparado la exactitud diagnóstica de una puntuación de la ICG de 2 con una puntuación estimada resultante de la suma del valor de viabilidad de las cuatro glándulas (ICG-4).

Métodos

Un total de 50 pacientes (66% mujeres, mediana de edad 49,4 años) fueron operadas practicándose una tiroidectomía total con identificación de las 4 glándulas paratiroides. El grado de la ICG se clasificó como 0, color negro (no vascularizada), 1, gris/heterogéneo (parcialmente vascularizada) y 2, blanco (bien vascularizada).

Resultados

La exactitud diagnóstica del umbral óptimo de la suma del ICG-4 de ≤3 fue del 85% (intervalo de confianza del 95% 70,9-92,8), inferior a la exactitud diagnóstica del 92% (80,8-97,8) del ICG-2. Con ambas puntuaciones se detectaron 2 casos de falsos negativos, pero las tasas de falsos positivos fueron menores con el ICG-2 (18,2% vs. 57,1%).

Conclusiones

El sistema ICG-2 predice con más exactitud la hipocalcemia post-tiroidectomía en el postoperatorio inmediato que el sistema ICG-4.
