Bleeding esophageal varices

Bleeding esophageal varices refers to an acute, life-threatening gastrointestinal emergency characterized by the rupture and hemorrhage of pathologically dilated submucosal veins in the distal esophagus This clinical state most commonly arises as a severe complication in patients with chronic liver disease, advanced cirrhosis, or portal vein obstruction Pathophysiologically, sustained portal hypertension diverts splanchnic blood flow into lower-pressure portosystemic collateral vessels, leading ...

Bleeding esophageal varices refers to an acute, life-threatening gastrointestinal emergency characterized by the rupture and hemorrhage of pathologically dilated submucosal veins in the distal esophagus

Pathophysiologically, sustained portal hypertension diverts splanchnic blood flow into lower-pressure portosystemic collateral vessels, leading to progressive vascular engorgement and vessel wall thinning When rising luminal pressure and wall tension exceed the elastic capacity of these enlarged collaterals, catastrophic rupture occurs, presenting clinically with sudden hematemesis, melena, and rapid progression toward hemodynamic instability or hypovolemic shock
