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] The dilated vessels result in intestinal bleeding. [3]
In medicine (gastroenterology), angiodysplasia is a small vascular malformation of the gut. It is a common cause of otherwise unexplained gastrointestinal bleeding and anemia . Lesions are often multiple, and frequently involve the cecum or ascending colon , although they can occur at other places.
Portal hypertensive gastropathy can also be treated with endoscopic treatment delivered through a fibre-optic camera into the stomach. Argon plasma coagulation and electrocautery have both been used to stop bleeding from ectatic vessels, and to attempt to obliterate the vessels, but have limited utility if the disease is diffuse.
Gastric varices; Gastric antral vascular ectasia; Dieulafoy's lesions; Duodenal causes: Duodenal ulcer; Vascular malformation, including aorto-enteric fistulae. Fistulae are usually secondary to prior vascular surgery and usually occur at the proximal anastomosis at the third or fourth portion of the duodenum where it is retroperitoneal and ...
Gastric cancer: Antrectomy could remove gastric tumors developing in the antrum. [1] Gastric antral vascular ectasia syndrome (GAVE): The disease is characterized by excessive bleeding in the stomach. By removing the bleeding site and reconnecting the upper stomach with the intestines, antrectomy controls chronic bleeding and ensures gastric ...
Dieulafoy's lesion (French:) is a medical condition characterized by a large tortuous artery [2] most commonly in the stomach wall that erodes and bleeds.It can present in any part of the gastrointestinal tract. [3]
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.
Delay in the diagnosis of SMA syndrome can result in fatal catabolysis (advanced malnutrition), dehydration, electrolyte abnormalities, hypokalemia, acute gastric rupture or intestinal perforation (from prolonged mesenteric ischemia), gastric distention, spontaneous upper gastrointestinal bleeding, hypovolemic shock, and aspiration pneumonia.
