[Hemodynamic studies of portal hypertension with esophageal varices; a role of left gastric artery and vein].
Hemodynamic states of portal hypertension with esophageal varices were studied by scintiphoto splenoportography (SSP) and left gastric angiographies in relation to endoscopic findings. The cases were classified into two groups by SSP. The flow of left gastric vein was hepatofugal in Group I (77.3%), and it was hepatopetal or "to and fro" in Group II (22.7%). Endoscopically, the varices were more severe in Group I than those in Group II. The diameter of left gastric vein was significantly larger in Group I. The values of K.ICG and liver function by blood analysis were also poor in Group I. Moreover, the cases with varices supplied by both left gastric artery and vein showed more severe endoscopic findings and history of hematemesis than those in the cases with varices supplied by left gastric artery alone. In conclusion, the results suggested that the flow of left gastric vein was closely related to the severity of esophageal varices.
