The VeinViewer Vision ® is a near-infrared vascular imaging device that creates a digital image of the superficial vein onto the surface of the skin in real-time using near-infrared imaging technology. It can make puncture of blood vessels easy and hand free, while being clean. The vein, but not an artery, can be demonstrated to a subcutaneous depth of 1 cm. We report our experience of using this device for the examination and treatment of varicose vein. While it is difficult to detect the saphenous vein, superficial varicose veins are comparatively visible. The venous network and filling, which are difficult to visualize with ultrasonography, can be evaluated satisfactorily. Moreover, it is useful to determine the puncture area and to evaluate the effect with sclerotherapy. This unique device can be operated cleanly and non-invasively. Therefore, it is anticipated that it will be further developed and used for various vascular surgical procedures in the future.
