简介：虽然，成功的游离皮瓣在过去几年中，更多的细节，其特点可能会改善皮瓣的临床效果。本研究探讨两种不同类型的显微外科游离皮瓣在术后过程中的温度调节能力作为神经再支配的标志。研究方法：共22例患者接受了两种不同类型的皮瓣移植后的检查：背阔肌皮瓣（LDM）（n = 11）和股前外侧（ALT）皮瓣（n = 11）。术后6个月和9个月对患者进行检查。暴露于冷水和温水（10摄氏度和35摄氏度）后，使用“O2 C”设备进行多次测量，重点是血液速度和流量。结果：两种皮瓣在热应力作用下，局部血流量及血流速度均有改善的趋势。我们记录了更多的生理温度调节过程中的热应力的LDM皮瓣，当与ALT皮瓣在一段时间内测量。总结：我们认为，在LDM皮瓣的肌肉部分的存在下，可能会提供更好的条件，温度调节的基础上改善神经和血管再生。然而，进一步的研究应澄清的病理生理学背景，使这些有趣的结果临床应用。(C)2011 Wiley Periodicals，Inc.显微外科31：650-654，2011年。
Introduction: Although, the success of free flaps has increased in the last years, more details about its characteristics might improve the clinical outcome of the flaps. This study examined the thermoregulatory ability as a sign of neural re-innervation of two different types of microsurgical free flaps in the postoperative course. Methods: A total of 22 patients were examined after grafting two different flap types: The latissimus dorsi myocutaneous (LDM) flap (n = 11) and the anterolateral thigh (ALT) flap (n = 11). Patients were examined 6 and 9 months postoperatively. After exposure to cold and warm water (10 degrees C and 35 degrees C), multiple measurements were performed with the focus on blood velocity and flow using the 'O2C' device. Results: Both examined flaps showed a tendency for improvement in local blood flow and velocity due to thermal stress. We recorded a more physiological thermoregulation during thermal stress for the LDM flap, when compared with the ALT flap over a measured period of time. Conclusion: We believe that the presence of the muscle portion in the LDM flap may offer better conditions for thermoregulation based on the improvement of neural and vascular regeneration. However, further studies should clarify the pathophysiological backgrounds, to make these interesting results clinically applicable. (C) 2011 Wiley Periodicals, Inc. Microsurgery 31: 650-654, 2011.
