Objective. We investigated the efficiency of laser speckle flowgraphy for evaluating blood flow in free flaps used for plastic surgery. Methods. We measured blood flow using a visual laser meter capable of providing two-dimensional color graphic representations of flow distribution for a given area using a dynamic laser speckle effect. Using laser speckle flowgraphy, we examined the blood flow of 20 free flaps applied following the excision of head and neck tumors. Results. After anastomosis of the feeding and draining blood vessels and sewing the flap, musculocutaneous (MC) flaps showed significantly lower blood flow than jejunal or omental flaps (P < .05). The ratio of blood flow decrease from the edge to the center was significantly greater in MC flaps than in jejunal or omental flaps (P < .001). Conclusion. Laser speckle flowgraphy is useful for the perioperative measurement of blood flow in free flaps used in plastic surgery. This method is a highly useful, practical, and reliable tool for assessing cutaneous blood flow and is expected to be applicable to several clinical fields.
目的。我们研究了激光散斑血流图在评估整形手术中游离皮瓣血流方面的效率。方法。我们使用一种视觉激光仪测量血流，该仪器能够利用动态激光散斑效应为给定区域提供血流分布的二维彩色图形表示。我们使用激光散斑血流图检查了20例头颈部肿瘤切除术后应用的游离皮瓣的血流情况。结果。在吻合供血和引流血管并缝合皮瓣后，肌皮（MC）瓣的血流明显低于空肠瓣或网膜瓣（P < 0.05）。MC瓣从边缘到中心的血流减少比例明显大于空肠瓣或网膜瓣（P < 0.001）。结论。激光散斑血流图可用于整形手术中游离皮瓣血流的围手术期测量。该方法是评估皮肤血流的一种非常有用、实用且可靠的工具，有望应用于多个临床领域。
