2024年7月23日 · Gastric varices are enlarged and swollen blood vessels (veins) within the lining of your stomach. They form when something blocks the blood flow to your liver. Blood diverts to the smaller vessels in your stomach, which can’t handle the pressure and swell.

Gastric varices are dilated submucosal veins in the lining of the stomach, which can be a life-threatening cause of bleeding in the upper gastrointestinal tract. They are most commonly found in patients with portal hypertension, or elevated pressure in the portal vein system, which may be a complication of cirrhosis.

2021年6月5日 · Gastric varices are dilated submucosal collateral veins that develop in the setting of portal hypertension due to any etiology with or without cirrhosis. Compared to esophageal varices, gastric varices are less common occurring in approximately 20% of cirrhotic patients.

Gastric varices (GV) are responsible for 10-30% of all variceal hemorrhage. However, they tend to bleed more severely with higher mortality. Around 35-90% rebleed after spontaneous hemostasis. Approximately 50% of patients with cirrhosis of liver harbor gastroesophageal varices.

2021年12月31日 · Gastric varices (GV) are a bunch of vessels in the mucosa/submucosa of the stomach and part of a complex collection of vascular shunts between the portal and systemic circulation. 1,2 The prevalence of GV with portal hypertension ranges from 17% to 25% 3–5 as compared with 85% for esophageal varices (EV). 6 The incidence of GV varies from 16% at...

This article describes the classification, pathophysiology, and natural history of gastric varices; summarizes the available evidence regarding medical, endoscopic, and endovascular management of gastric varices; and provides recommendations on how to integrate these options.

Gastrointestinal varices are abnormally dilated submucosal veins in the digestive tract due to portal hypertension and can potentially cause life-threatening bleeding. Prevalence of varices increases with the severity of liver disease (Child-Pugh class A 42.7%, class B 70.7% and class C 75.5%) [2, 10]. The Child-Pugh score is described in Table 1.

The most dangerous collaterals occur in the distal esophagus and gastric fundus, causing engorged, serpentine submucosal vessels known as varices. These varices partially decompress portal hypertension but can rupture, causing massive gastrointestinal (GI) bleeding.

2024年6月28日 · Gastric varices are an important portosystemic collateral pathway, occurring in ~20% of patients with portal hypertension. They are considered distinct from esophageal varices in that they have a propensity to hemorrhage at comparatively lower portal pressures 1, and are also associated with higher mortality rate with hemorrhage (range 14-45%) 2.

Gastric varices are dilated submucosal veins in the stomach, similar to esophageal varices, which can lead to serious and life-threatening bleeding. This condition is most commonly associated with portal hypertension, often resulting from liver cirrhosis.
