Abstract
We measured the portal circulatory hemodynamic parameters in 10 cirrhotic patients with portal hypertension and esophageal varices to determine the significance of esophageal variceal pressure. In 4 patients (group I), the temporary portal vein occlusion produced significant elevations in both the esophageal variceal pressure and the portal venous pressure. The results of the portal circulatory hemodynamic assessment in this group were consistent with the predominance of the backward flow mechanism. In the remaining 6 patients (group 11), however, portal vein clamping resulted in a slightly increased esophageal variceal pressure with an enormous increase in the portal pressure. The forward flow mechanism thus appeared to be predominant in group II. In other words, the results of the pressure measurements were consistent with the functional separation of the hemodynamics in the esophageal varices and portal trunk in group 11 and the functional hemodynamic continuity in group I. This functional separation between the esophageal varices and the portal trunk in group II might therefore have resulted from the increased blood flow in the lesser splanchnic region.
