Esophageal Varices - StatPearls - NCBI Bookshelf
2023年8月7日 · Esophageal varices are dilated submucosal distal esophageal veins connecting the portal and systemic circulations. This happens due to portal hypertension (most commonly a result of cirrhosis), resistance to portal blood flow, and increased portal venous blood inflow. The most common fatal complication of cirrhosis is variceal rupture; the severity of liver disease …
Pathophysiology and Treatment of Variceal Hemorrhage
Portal hypertension results from increases in portal flow and portal vascular resistance. Factors increasing portal blood flow are predominantly humoral. Resistance to portal flow has a fixed component due to distortion of the vasculature by cirrhotic nodules and a variable component that is related to vasoactive substances. Varices result from an increase in portal pressure. Factors ...

Diagnosis and Management of Esophagogastric Varices - PMC
The increased resistance is mainly due to a combination of structural changes (distortion of the liver microcirculation by fibrosis, nodules, angiogenesis, and vascular occlusion) and dynamic changes (increased release of vasoconstrictors as angiotensin-II, norepinephrine, thromboxane A2 and endothelins, and the reduced production of vasodilators as nitric oxide).
