Hemodynamic analysis of esophageal varices in patients with liver cirrhosis using color Doppler ultrasound

Figure 1 Relationship between hemodynamics of the LGV and the size of esophageal varices. A: Hepatopetal blood flow in the LGV; B: hepatofugal blood flow in the LGV; C: hepatofugal blood flow in the LGV.

Figure 2 Hepatofugal flow velocity in LGV in relation to the size of esophageal varices.

Figure 3 Hepatopetal blood flow in the LGV of normal subjects.

Figure 4 Change in flow direction in the LGV. A: Hepatopetal blood flow in the LGV before ingestion of glucose; B: changes of flow direction from hepatopetal to hepatofugal after ingestion of glucose.

Figure 5 Doppler sonograms in the LGV with hepatofugal blood flow before (A) and after (B) ingestion of glucose in a patient with a significant response to glucose.

Figure 6 Changes in blood flow in the PV and LGV of patients with hepatofugal blood flow before and after ingestion of glucose.
