"Risk factors" changes in the distal esophagus eg, gastroesophageal varices — These have been postulated to increase the risk of variceal hemorrhage, risk evidence to factors this view is weak; studies indicate that gastroesophageal reflux does not initiate or play a role in esophageal hemorrhage [ 1617 ]. Note the flow defect of the distal portal vein caused by "risk" flow open arrowhead. Redirection of flow through the left gastric vein secondary to portal hypertension or portal factors occlusion. Updating consensus in portal hypertension: Presinusoidal venous block eg, portal vein thrombosis, schistosomiasis, primary http://blogaidz.xyz/1/6825.html cirrhosis - Characterized by elevated portal venous pressure and a normal wedged factors venous pressure WHVP ; these abnormalities cannot be detected by surrogate measurement WHPV, Riskbecause the measured pressure represents portal pressure in the segment distal to the lesions, which is normal; however, direct measurement of esophageal varices portal venous pressure esophageal varices be elevated.
