Schematic diagram of Sarin's Endoscopic Classification of Gastric Varices: Fundal varices are included in two of the groups: (A) Type 1 gastroesophageal varices (GOV 1) are typically continuation of esophageal varices into the lesser curvature varices. (B) Type 2 gastroesophageal varices (GOV 2) when the esophageal and fundal varices are present in continuity over the cardia, (C) Type 1 isolated gastric varices (IGV 1), that are usually fundal gastric varices. (D) Type 2 isolated gastric varices (IGV 2) are gastric varices at ectopic sites in the stomach outside the cardiofundal region or the first part of the duodenum. An alternative classification based on vascular anatomy (determined by dominant feeder veins) has been proposed and is especially useful in consideration of balloon retrograde transvenous obliteration.
