Abstract
Abstract: A 64‐year‐old female was admitted to our hospital with enlarged solitary gastric varices. Cardiofornical varices were seen using an endoscopy. We performed balloon‐occluded retrograde transvenous obliteration (B‐RTO) for gastric varices using 5% ethanolamine oleate. We observed the gastric varices before and after B‐RTO using endoscopic color Doppler ultrasonography (ECDUS). Prior to B‐RTO, the intramural and extramural blood flow coming from gastric varices were detected. The intramural blood flow produced a to and fro color image on ECDUS. The blood flow velocity was 31.2 cm/sec. The amount of blood flow was 2.40 liter/min. Seven days after the B‐RTO, high echo lesions were observed in the gastric varices which indicated that the thrombosis and color flow image had also decreased. Twenty one days after B‐RTO, the color flow image of the gastric varices had nearly disappeared and had completely disappeared after 3 months. In this case, ECDUS was an extremely useful modality for viewing the therapeutic effects of B‐RTO.
