ObjectiveTo investigate the combined use of a nanocarbon (NC) suspension and low-dose ^99mTc-MIBI for parathyroid localization during surgery in patients with secondary hyperparathyroidism (sHPT).MethodsBetween March 2010 and September 2015, 40 patients with sHPT were enrolled in this study and were randomized to receive either low-dose ^99mTc-MIBI+NC (group I) or low-dose ^99mTc-MIBI (group II). Pre- and post-operative serum levels of intact PTH (iPTH), calcium and phosphorus between groups were compared and the intra-operative radioactive counts of the parathyroid glands were measured.ResultsThe post-operative iPTH level was significantly lower in patients of group I (24.2±31ng/L) than in those of group II (106±155ng/L) (P=0.03) while there were no significant differences in intra-operative parathyroid gland radioactive counts between the groups. The duration of the surgical procedure was shorter for patients of group I than patients of group II. There were no serious intra-operative or post-operative complications.ConclusionThe combined use of an NC suspension and ^99mTc-MIBI for patients with sHPT is strongly recommended for the localization of parathyroid glands during surgery and is likely to improve clinical outcomes for patients.
