We investigated the hemodynamics in 30 cases (untreated group) with esophageal varices before EVL, AS-EIS combined therapy and in 18 cases with long-term obserbation after therapy (long-term follow-up group), using color-Doppler endoscopic ultrasonogra-phy (CD-EUS). 1. Flow direction of left gastric vein (LGV) was hepatofugal in most cases of both groups, and its velosity was not significantly different. 2. In long-term followed-up group, poterior branch dominant type (type PD) was more increased in the branch patterns of LGV. 3. The size of the paraesophageal veins was significantly larger. 4. Detection rate of enlarged perforating vein (EPV) was significantly lower, as compared with untreated group. It is suggested that the reccurence prognosis may improve because posterior branch and paraesophageal veins may develop after long-term follow up and function as an extravariceal shunt, while anterior branch and EPV may disappear. These findings are important for the reccurence factor after topical treatments of esophageal varices.
