The ideal monitoring tool to evaluate free flap success should be noninvasive, continuous, and reliable. A new device, the ViOptix Tissue Oximeter (ODISsey) based on near-infrared spectroscopy was evaluated in 30 patients undergoing autologous tissue perforator free flap breast reconstruction with continuous monitoring of the flap during elevation, transfer, and the postoperative period. The device accurately reflected the ischemic drop in oxygen saturation during flap transfer, and the hyperemic response after flow was reestablished. There were no flap failures, but in two patients, the device indicated a venous thrombosis before it was clinically obvious and allowed for expeditious flap salvage. The noninvasive nature of the device, the ability to replace and move the probe in the postoperative period, and the measurement of end organ oxygenation are all advantages over other currently available techniques.
评估游离皮瓣成功的理想监测工具应是非侵入性、连续且可靠的。一种基于近红外光谱的新型设备——ViOptix组织血氧仪（ODISsey），在30例接受自体组织穿支游离皮瓣乳房重建的患者中进行了评估，在皮瓣掀起、转移及术后期间对其进行连续监测。该设备准确反映了皮瓣转移过程中氧饱和度的缺血性下降以及血流重建后的充血反应。没有皮瓣失败的情况，但在两名患者中，该设备在临床明显表现之前就提示了静脉血栓形成，从而得以迅速挽救皮瓣。该设备的非侵入性、术后更换和移动探头的能力以及对终末器官氧合的测量，都是相对于目前其他现有技术的优势。
