Esophagogastric varices are considered to be the most common complication in patients with portal hypertension. Endoscopic ultrasonography not only visualizes the surface of the varices but also provides detailed information about their internal structure. The direction of blood flow can be determined and its velocity measured only via endoscopic color Doppler ultrasonography (ECDUS). This can show graphically esophageal varices, paraesophageal veins, and passageways in esophageal variceal patients and gastric varices, perigastric collateral veins in gastric variceal patients. It is important to evaluate the hemodynamics of the portal venous system when treating the esophago-gastric varices. ECDUS is a useful modality for the evaluation of the detailed hemodynamics and the therapeutic effects of esophago-gastric varices.
