The utilization criteria of stereophlebography since his creation by Cid dos Santos fifty years ago are analysed. During many years it was applied on all varicose and thrombophlebotic patients. At present, it is used only in cases where history, physical signs and non-invasive tests are not able to give a perfect knowledge of the situation. A replacement of the phlebography in its actual fashion in future time by some non-invasive technics like duplex-scan may be admitted. However, at present, it is still the more efficient and the most exact method for diagnosis of the venous disease of the limbs.

A summary of several techniques for visualization of the portal venous system, developed in the last four decades, is given. The various methods are divided into direct and indirect techniques. Indirect arterial portography is the method of choice in patients with cirrhosis of the liver, being the most physiologic technique, visualizing the total portal venous system including arterial supply and having a low complication risk.
