“…We previously reported use of ECDUS for evaluating the hemodynamics of esophago-gastric varices [11,12]. Iwase et al [13] reported that ECDUS is a useful method for the evaluation of gastric varices and for endoscopic obliteration of varices with cyanoacrylate glue.…”

“…In addition, fast Fourier transform analysis can be used to evaluate flow patterns and to calculate the velocity of blood flow at gastric varices [4][5][6]. Based on their locations, ordinary gastric varices can be classified as either fundal, or cardiac and fundal (located between the cardiac orifice and the fundus); however, in no cases of ordinary gastric varices examined using ECDUS did varices show expansion to the curvatura ventriculi major of the gastric body [4].…”

“…Additional images resulting from ECDUS color analysis of gastric variceal flow clearly depicted a round fundal region at the center, with varices that expanded to the curvatura ventriculi major of the gastric body on gastric varices due to splenic vein occlusion (Figures 3a and 3b) [23]. Variceal location of ordinary gastric varices was classified as fundal (located far from the cardiac orifice) and cardiac and fundal (located between the cardiac orifice and the fundus), however, there was no case with varices expanding to the curvatura ventriculi major of the gastric body with ECDUS findings of ordinary gastric varices [30]. These data provide specific findings that can function as hallmarks of gastric varices due to splenic vein occlusion.…”

“…In a previous report, Sato et al described the utility of endoscopic color Doppler ultrasonography (ECDUS) in patients with gastric varices [30]. Relative to EUS, ECDUS color images of blood flow in vessels allow for detailed sonographic visualization of vessels and evaluation of vascular blood flow for the diagnosis of gastric varices [31,32].…”

Sutton et al. reported that 35% of their cases of isolated splenic vein occlusion were caused by tumors and only 17% by pancreatitis [9]. On the other hand, Sakorafas et al. found that pancreatitis was the etiology in 87 (60%) of 144 cases, while pancreatic malignancy was detected in only [13] (9%) of the patients [7], and recent reviews have clarified acute or chronic pancreatitis to be the probable cause of splenic vein thrombosis in the majority of cases [18]. There is a possible pathogenetic mechanism implying the increased intra-abdominal pressure leading to compression of the splenic vein in the case of pancreatic pseudocyst [19,20].Due to splenic vein occlusion, splenic venous flow must drain into collateral veins (short gastric vein and left gastroepiploic vein). Then, the increased blood flow dilates the submucosal veins of stomach, resulting in gastric varices (Figure 1). Because blood drainage is diverted by the coronary vein into the patent portal system, the presence of gastric varices without esophageal varices is a very specific sign of splenic vein occlusion [17]. This condition, which is commonly silent clinically, can cause hypersplenism or gastrointestinal hemorrhage.Although splenic vein occlusion is commonly silent clinically, AbstractGastric varices that arise secondary to splenic vein occlusion can result in hypersplenism or gastrointestinal hemorrhaging. This article review gastric varices secondary to splenic vein occlusion due to pancreatic diseases with regard to causes of the condition, as well as diagnostic and therapeutic approaches.Diagnosis of gastric varices is made following esophago-gastro-duodenoscopy, and splenic vein occlusions are diagnosed from enhanced computed tomographic scans in almost all cases. Specific findings of gastric varices secondary to splenic vein occlusion are based on endoscopic ultrasonographic color flow images of gastric variceal flow that clearly depicted round cardiac and fundal regions at the center, with varices expanding to the curvatura ventriculi major of the gastric body.Several treatment options for gastric variceal bleeding secondary to splenic vein occlusion have been proposed. Splenectomy, which decompresses the short gastric vein by cutting off inflow, has generally been considered the best treatment of choice in such condition. Endoscopic injection sclerotherapy using cyanoacrylate, is useful in the treatment of bleeding gastric varices due to splenic vein occlusion. As patients with splenic vein occlusion have normal portal pressure and normal hepatic function, portal systemic shunting is not indicated. Splenic arterial embolization, which reduces blood flow through the sp...
