The technique employed has usually been injection of one of the jejunal tributaries with 30 c.c. of 70 per cent diodone. Occasionally some other tributary vein has been used. Of late, when splenectomy is indicated, splenic pulp injection was made at operation. Two radiographs are taken. This gives a rough indication of speed of flow. Percutaneous splenic puncture venography is thought to have some dangers in cases of portal hypertension. The appearances of intra-hepatic block due to cirrhosis, and the different types of extra-hepatic block, are discussed. Portal hypertension and stasis without obstruction are illustrated. The main value of the method has been the demonstration of veins suitable for anastomosis. It has been useful to know from the venogram, that gastric varices are present in a patient who had no oesophageal varices and who subsequently bled. Stream-lining in the por...
