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.
Balloon-occluded retrograde transvenous obliteration (BRTO) is an endovascular procedure used for the treatment of gastric varices.When performing the procedure, an interventional radiologist accesses blood vessels using a catheter, inflates a balloon (e.g. balloon occlusion) and injects a substance into the variceal blood vessels that causes blockage of those vessels.
The Sugiura procedure was originally developed to treat bleeding esophageal varices and consisted mainly of an esophagogastric devascularization. It was developed in Japan in 1973 [ 1 ] as a nonshunting technique that achieved variceal bleeding hemostasis by interrupting the variceal blood flow along the gastroesophageal junction.
Gastric antral vascular ectasia (GAVE) is an uncommon cause of chronic gastrointestinal bleeding or iron deficiency anemia. [ 1 ] [ 2 ] The condition is associated with dilated small blood vessels in the gastric antrum , which is a distal part of the stomach . [ 1 ]
Patients with portal hypertensive gastropathy may experience bleeding from the stomach, which may uncommonly manifest itself in vomiting blood or melena; however, portal hypertension may cause several other more common sources of upper gastrointestinal bleeding, such as esophageal varices and gastric varices. On endoscopic evaluation of the ...
About half of cases are due to peptic ulcer disease (gastric or duodenal ulcers). [3] Esophageal inflammation and erosive disease are the next most common causes. [3] In those with liver cirrhosis, 50–60% of bleeding is due to esophageal varices. [3] Approximately half of those with peptic ulcers have an H. pylori infection. [3]
Upper gastrointestinal bleeding can be caused by peptic ulcers, gastric erosions, esophageal varices, and rarer causes such as gastric cancer. The initial assessment includes measurement of the blood pressure and heart rate, as well as blood tests to determine the hemoglobin.
These vessels are fragile and often hemorrhage into the GI tract. (See esophageal, gastric, rectal varices). [citation needed] A TIPS procedure decreases the effective vascular resistance of the liver through the creation of an alternative pathway for portal venous circulation. By creating a shunt from the portal vein to the hepatic vein, this ...
