This book is not meant to be a textbook or a handbook of phlebography of the lower limbs. It is an atlas aimed only at teaching one how to read an interpret phlebograms, and is of considerable importance as it represents the standard investigatory method used to check the reliability of other diagnostic methods concerning venous circulation. Regarding diagnosis, nothing is more certain than the phlebographic demonstration of a thrombus; moreover, even if the thrombus is not demonstrable, as in certain phlebites. it is still possible to establish the diagnosis with adequate knowledge of the radio anatomy of the non-opacified veins and the demonstration of marked collateral circulation. Therefore this investigation must be carried out very carefully with particular attention to interpretation. The technique was first used in man in 1923 and is now employed world wide; better tolerated contrast materials render it almost innocuous; the occurrence of very few incidences of non-tolerance does not diminish the value of this method. We have purposely reduced the text to legends of the illustration and withheld the bibliography in so far as it is meant to be a teaching program by way of pictures without any reference to past or present publications.
