ABSTRACT
INTRODUCTION: In total thyroidectomy, indocyanine green (ICG) angiography has mainly been evaluated at end of procedure to predict postoperative hypoparathyroidism. By using it during surgery, we sought to determine whether it could also be an aid to the surgeon.
OBJECTIVE: To determine whether ICG used intraoperatively in total thyroidectomy modified the surgical procedure.
MATERIAL AND METHOD: Thirty-two patients who underwent ICG angiography during total thyroidectomy were included in our single-center retrospective study. The number of parathyroid (PT) glands visualized in white light and on ICG angiography was collected, as well as PT vitality of at end of surgery according to these two modalities. Vitality scores were 0 (no vascularity), 1 (moderately vascularized) or 2 (well vascularize d). Postoperative calcemia at D1, D2 and D7 was analyzed.
RESULTS: In the 32 operations, the surgical procedure was modified in 10 cases (31%). The average number of PTs detected was 2.4 (77 PT) on ICG angiography and 2 (65 PT) in white light. Eleven patients (37.5%) had postoperative hypocalcemia. Cumulative vitality scores at end of procedure were 3.75/8 and 3.37/8 in white light and on ICG angiography respectively (P=0.648). The use of the device did not predict the occurrence of postoperative hypocalcemia.
CONCLUSION: Indocyanine green angiography used in thyroid surgery could assist the surgeon in the identification of PT glands, sparing them in one third of cases.
