Esophageal varices are extremely dilated sub-mucosal veins in the lower third of the esophagus. [1] ... At gradients greater than 10 mmHg, blood flowing through the ...
TIPS is a life-saving procedure in bleeding from esophageal or gastric varices. A randomized study showed that the survival is better if the procedure is done within 72 hours after bleeding. [2] TIPS has shown some promise for people with hepatorenal syndrome. [3] It may also help with ascites. [4]
WHVP is used to estimate the portal venous pressure by reflecting not the actual hepatic portal vein pressure but the hepatic sinusoidal pressure. It is determined by wedging a catheter in a hepatic vein, to occlude it, and then measuring the pressure of proximal static blood (which is reflective of pressure in the sinusoids).
Portal hypertension is defined as increased portal venous pressure, with a hepatic venous pressure gradient greater than 5 mmHg. [3] [4] Normal portal pressure is 1–4 mmHg; clinically insignificant portal hypertension is present at portal pressures 5–9 mmHg; clinically significant portal hypertension is present at portal pressures greater than 10 mmHg.

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 ...
The esophageal veins drain blood from the esophagus to the azygos vein, in the thorax, and to the inferior thyroid vein in the neck. It also drains, although with less significance, to the hemiazygos vein , posterior intercostal vein and bronchial veins .

Varices usually occur in the venous system, but may also occur in arterial or lymphatic vessels. [1] Examples of varices include: [citation needed] Varicose veins, large tortuous veins usually found on legs; Sublingual varices; Esophageal varices, commonly stemming from cirrhosis of the liver, also known as oesophageal varicose
