“…Since Rappaport's experiment with dogs (Rappaport 1951) and its clinical applications by Tori (1953), the hepatic venous catheterization has become an important diagnostic method for hepatic diseases, especially in cases of portal hypertension. In cases of liver cirrhosis, the hepatic venous branching decreases in number and shows a zigzag running or an irregular wall or waving, which may be expressed as a "dead tree appearance".…”

The hepatic venography and wedged hepatic venous pressure measurement were performed in 35 patients with portal hypertension using a balloon catheter, and the results were compared with those obtained by the conventional method.It was revealed that the balloon catheter visualized a broader area of the liver and showed more accurate wedged hepatic venous pressure than the conventional catheter, thereby demonstrating that this is an excellent diagnostic tool for patients with portal hypertension. hepatic catheterization; hepatic venography; balloon catheter; wedged hepatic venous pressure; portal hypertension It is well known that several data obtained from hepatic venous catheterization are extremely useful for determination of hepatic disorders in cases of portal hypertension.However, there were not a small number of cases with unsatisfactory venography or cases impossible of determining the wedged hepatic venous pressure in cirrhotic patients. On the other hand, Groszmann et al. (1979) published an interesting report on the use of a balloon catheter as a method to visualize hepatic veins more clearly and also to measure wedged hepatic venous pressure more accurately.This method was adopted in our department and the results obtained were better than those before. PATIENTS AND METHODThirty-five patients with portal hypertension were subjected to the study during evaluation for operations, who were admitted to our department in the past 2 years. The hepatic diseases were liver cirrhosis in 24 cases and idiopathic portal hypertension (portal hypertension due to hepatic fibrosis without cirrhosis) in ll.The catheter used in this investigation was an 8.5 F balloon catheter (potter-LukasNo. 1 USCI's with the balloon capacity of 3 ml). The catheter was introduced 2 cm into the right hepatic vein through the right basilic vein or saphenous vein.After the balloon was expanded with 2-3 ml of physiological saline, about 2 ml of the contrast medium was injected through the catheter and the complete closure of the hepatic vein with the balloon was confirmed.Maintaining this position, the wedged hepatic venous pressure was measured, using a graduated manometer filled with heparinized saline. The zero point through the pressure study was set about 10 cm above the bed. After that the venography was performed.

“…(Tori, 1953) or direct transhepatic portography (Bierman, Steinbach, White, and Kelly, 1952) requires a high injection pressure which may damage the liver parenchyma. Parks and Couch (1962) described one case in which they catheterized a large collateral vessel arising from the haemorrhoidal plexus, but this technique requires a surgical exposure with a general anaesthetic or a pudendal block.…”

“…TORI (1953) demonstrated that it was possible to inject contrast medium into the hepatic veins from a catheter introduced through an elbow vein. Ueing this method, several authors have studied hepatic veins in human subjects angiographicauy ( SERVELLO and DALLA PALMA, CELIS et coll., NEY, and others).…”
