[Transfemoral portography (author's transl)].
In 15 cadavers the portal vein was dissected and punctured from the inferior vena cava by means of a coaxial needle (Johnson needle) introduced through the femoral vein. Success was confirmed by screening after contrast injection, by appropriate radiographs and following the use of coloured material by inspection. A modification of the technique was the use of a catheter introduced into the femoral vein by the Seldinger technique. In only one case was extravasation observed, and there was not incorrect injection into the inferior vena cava. These experiments demonstrate the feasibility of transfemoral portography. Its use in patients would also appear to be possible. The puncture is best carried out by radiographic observation and real time ultra sound. Possible complications from damage to neighbouring structures and from bleeding are possible, though apparently not serious. The indications and possible modifications of transfemoral portography are discussed and compared with other methods. The possibility of performing a portocaval shunt by means of the catheter in order to stop bleeding from oesophageal varices is stressed.
