To assess the relationship between the fluid mechanics in the left gastric venous area and the portal trunk, manometric measurements were made in patients with or without cirrhosis of the liver. In ten normal subjects, temporary portal vein occlusion produced comparable elevation in both the occluded left gastric venous pressure (OLGP) and the portal vein pressure (PVP); 152-429 mm of water in OLGP and 115-452 mm of water in PVP. In sixty cirrhotic patients, however, the portal vein occlusion resulted in far less increase in OLGP than that in PVP; 281-365 mm of water in OLGP and 281-540 mm of water in PVP. In other words, regarding pressure measurements, the relationship was 'separated' in cirrhotics, but 'continuous' in normal subjects. Mathematical analysis of the data using a modification of Wheat-stone bridge model suggested that the arteriovenous flow resistance in the left gastric venous area of cirrhotics was reduced to less than one fifth of that in the controls. It would appear that the increased flow capacity as a result of a reduced arteriovenous flow resistance is responsible for the functional 'separation' from the portal trunk. |
