[Retrograde pancreatic phlebography with simultaneous balloon occlusion of portal and arterial flow. An experimental study (author's transl)].

The possibility of demonstrating the venous system of the entire pancreas by retrograde portal contrast injection with simultaneous balloon occlusion of the portal vein, coeliac axis and superior mesenteric artery was investigated in 12 dogs. In seven cases good filling of the larger pancreatic veins was obtained. Portal and arterial pressure relationships altered considerably during various experimental conditions. A rise in serum transaminases was observed only once when there was thrombosis of the portal vein and branches of the hepatic veins. Apart from this, there was no rise in transaminases or alphaamylase. Histologically there were only minor changes in the liver after total occlusion of 40 minutes, the occlusion having been performed over periods of six minutes with two to five minutes of flow alternating. The application of this method to man is discussed.

[Transvenous cholangiography in the differential diagnosis of biliary stasis (author's transl)].

Transvenous cholangiography is an alternative to the direct puncture of the biliary tract. It was successfully performed in 13 of 21 patients of a personal series. The method does not require stand-by facilities for operation and is suitable for differentiating intra- from extrahepatic causes of biliary stasis, as well as for the demonstration of cause and localization of obstructive jaundice. Subcapsular liver haematoma with a rupture into the peritoneal cavity and bilihaemia were the main complications (one case of the former). The procedure is contraindicated in acute cholangitis and after cholangitic episodes.

[Retrograde renal phlebography with balloon occlusion of the renal artery. Technique and scope of a new method (author's transl)].

A new method of retrograde phlebography of the kidney is described; it is carried out by using a balloon catheter in the renal artery for occluding the circulation. The procedure has been carried out in 13 patients without complication. Early experience has provided very good results in the diagnosis of malignant renal tumours; invasion into the venous system can be demonstrated radiologically. In particular, in cases of carcinoma of the renal pelvis, this method represents a significant improvement of the hitherto unsatisfactory angiographic techniques.

[The results of transvenous cholangiography (contrast media)].

Transvenous cholangiography is a method for the direct demonstration of the biliary passages described by Hanafee and Weiner; its main indication is in the investigation of obstructive jaundice. This method, which does not require immediate subsequent operation, was used in 41 patients. In three patients catheterisation of hepatic veins was unsuccessful. Of the remaining 38 patients, puncture of a bile duct was successful in 20. In 29 patients biliary obstruction was present, and this was demonstrated in 19. In the absence of obstruction the procedure was successful in only one case. The main complications were a sub-capsular liver haematoma, with rupture into the abdominal cavity and one case of haemobilia.
