The term venous translucence (or translumination) has been used in phlebology since 1996 by surgeon Pedro Fernandes Neto during ambulatory clinical exams in Brazil. His results were published in the annals of the national and international congresses of angiology. Venous translucence is the process of reflective image visualization of veins by light, which reaches up to the superficial venous system. It is a non-invasive method. Since it is a simple, low-cost technique it can be repeated as needed, which is useful in disease-process monitoring. It is a new diagnostic procedure, still undergoing investigation; more analysis is necessary to hone its technical aspects. Venous translucence is based on optical physics. It is caused by the refraction, absorption and reflection of light (whose principle is the dispersion and absorption of light). The color which is not absorbed is reflected, and is the one that is seen. Therefore, venous translumination is based on the incidence of luminosity on the vein, where part of the light is absorbed and another reflected (supplying a silhouette of the vein in question).
