Popis:	For the past five years we have been interested in the development of a satisfactory and practical method of phlebography of the lower extremities. Our first endeavors were directed toward the study of the anatomical-spatial relationships of the deep veins (1). This formed a basis upon which future studies could be interpreted. After the trial of various methods presented in the literature, it was thought that the most physiological approach would be one in which the flow of the contrast material in the deep veins would be in the same direction as that of the blood. Our first method using this “homorrhoeic” (ὁμος, same; ῥω, flow) or “iso-flow”2 technic was presented in 1950 (2). The patient was placed on the Bucky table at 15 degrees from the horizontal to give some effect of gravity and to avoid the complications of possible syncope. Table I is a resume of the results of that method in terms of percentage of visualization. In an attempt to increase the percentage of visualization and to simulate more clo...
