Extrahepatic metastases of HCC are not rare. The possibility of extrahepatic metastases and the clinical features of extrahepatic metastases should be considered when examining patients with HCC, particularly those with advanced intrahepatic tumors, to enable precise evaluation of the spread of HCC and determination of the appropriate treatment method.

The results suggest that GAVE is related to severe liver damage and portal hypertension. APC has a high recurrence rate of GAVE in the medium term after treatment. EBL may be useful as a treatment for GAVE.

Endoscopic ultrasonographic evaluation of the hemodynamics in esophageal varices before and after EIS enables prediction of early variceal recurrence.

ECDUS is a useful modality for diagnosis of the hemodynamics of gastric varices and may allow the prediction of a high risk for hemorrhage.

A 53-year-old man was admitted to our hospital in August 1997 with enlarged gastric varices. Computed tomography (CT) showed splenic vein occlusion, gastric varices, and extra-gastric wall collateral veins. Color flow images of gastric varices were clearly visualized, and the velocity in the gastric varices was 19.6 cm/s via endoscopic color Doppler ultrasonography (ECDUS). The patient was diagnosed with gastric varices according to angiographic findings of splenic vein occlusion, and splenic arterial embolization was performed. Two weeks after the splenic arterial embolization, CT showed peripheral areas of low attenuation in the spleen, due to splenic infarction, with 70% of the spleen volume showing low attenuation. Eight months after the splenic arterial embolization, ECDUS revealed a decrease in gastric variceal color flow images, with the velocity in the gastric varices being 10.3 cm/s.
