Abstract

BACKGROUND

Intraoperative identification of parathyroid adenomas can be challenging. We hypothesized that low-doses methylene blue (MB) and near-infrared fluorescence (NIRF) imaging could be used to identify parathyroid adenomas intraoperatively.

METHODS

MB was injected intravenously after exploration at a dose of 0.5 mg/kg into 12 patients who underwent parathyroid surgery. NIRF imaging was performed using the Mini-FLARE imaging system.

RESULTS

In 10 of 12 patients, histology confirmed a parathyroid adenoma. In 9 of these patients, NIRF could clearly identify the parathyroid adenoma during surgery. Seven of these 9 patients had a positive preoperative (99m) Tc-sestamibi single photon emission CT (SPECT) scan. Importantly, in 2 patients, parathyroid adenomas could be identified only using NIRF.

CONCLUSION

This is the first study to show that low-dose MB can be used as NIRF tracer for identification of parathyroid adenomas, and suggests a correlation with preoperative (99m) Tc-sestamibi SPECT scanning.

摘要

背景

术中识别甲状旁腺腺瘤具有挑战性。我们推测低剂量亚甲蓝(MB)和近红外荧光(NIRF)成像可用于术中识别甲状旁腺腺瘤。

方法

在12例接受甲状旁腺手术的患者探查后,以0.5mg/kg的剂量静脉注射MB。使用Mini-FLARE成像系统进行NIRF成像。

结果

12例患者中有10例经组织学证实为甲状旁腺腺瘤。其中9例患者在手术期间NIRF能够清晰识别甲状旁腺腺瘤。这9例患者中有7例术前(99m)锝-司他比单光子发射计算机断层扫描(SPECT)扫描呈阳性。重要的是,有2例患者仅使用NIRF就能识别甲状旁腺腺瘤。

结论

这是第一项表明低剂量MB可作为NIRF示踪剂用于识别甲状旁腺腺瘤的研究,并提示其与术前(99m)锝-司他比SPECT扫描存在相关性。
