Abstract

Objectives

Hyperspectral imaging (HSI) provides spectral information about hemoglobin, water and oxygen supply and has thus great potential in perfusion monitoring. The aim of the present study was to investigate the feasibility of HSI in the postoperative monitoring of intraoral free flaps.

Methods

The 14 patients receiving reconstructive head and neck surgery with a radial forearm free flap were included. HSI was performed intraoperatively (t0), on Day 1 (t1), 2 (t2), 3–6 (t3), 7–9 (t4), 10–11 (t5) and 12–15 (t6) postoperatively. Flap tissue perfusion was assessed on defined regions of interest by calculating the perfusion indices Tissue Hemoglobin Index (THI), hemoglobin oxygenation (StO₂), Near Infrared Perfusion Index (NIR Perfusion Index) and Tissue Water Index (TWI).

Results

Image quality varied depending on location of the flap and time of measurement. StO₂ was >50 intraoperatively and >40 on t1 for all patients. A significant difference was found solely for TWI between t0 and t2 and t0 and t4. No flap loss occurred.

Conclusions

The use of HSI in the monitoring of intraoral flaps is feasible and might become a valuable addition to the current clinical examination of free flaps.

用于监测口腔游离瓣的高光谱成像：可行性研究。

目的：高光谱成像（HSI）可提供有关血红蛋白、水分和氧气供应的光谱信息，因此在灌注监测方面具有巨大潜力。本研究旨在探讨高光谱成像技术在口内游离皮瓣术后监测中的可行性：方法：本研究共纳入了 14 名接受头颈部重建手术并使用前臂桡侧游离皮瓣的患者。在术中（t0）、术后第 1 天（t1）、第 2 天（t2）、第 3-6 天（t3）、第 7-9 天（t4）、第 10-11 天（t5）和第 12-15 天（t6）进行 HSI。通过计算组织血红蛋白指数（THI）、血红蛋白氧饱和度（StO2）、近红外灌注指数（NIR Perfusion Index）和组织水分指数（TWI）来评估指定感兴趣区的皮瓣组织灌注情况：图像质量因皮瓣位置和测量时间而异。所有患者术中 StO2 均大于 50，t1 时大于 40。仅 TWI 在 t0 和 t2 以及 t0 和 t4 之间存在明显差异。没有发生皮瓣脱落：结论：在口内皮瓣监测中使用 HSI 是可行的，它可能成为目前游离皮瓣临床检查的重要补充。
