Can portal hypertension cause esophageal varices?

Can portal hypertension cause esophageal varices?

Varices most often occur in the esophagus or stomach as a result of portal hypertension. This is often because the liver tissue is scarred and blood cannot flow through normally. As the portal blood is rerouted due to the increased resistance, varices develop.

How does cirrhosis lead to esophageal varices?

Scarring (cirrhosis) of the liver is the most common cause of esophageal varices. This scarring cuts down on blood flowing through the liver. As a result, more blood flows through the veins of the esophagus. The extra blood flow causes the veins in the esophagus to balloon outward.

Is cirrhosis associated with esophageal varices?

Causes of esophageal varices include: Severe liver scarring (cirrhosis). A number of liver diseases — including hepatitis infection, alcoholic liver disease, fatty liver disease and a bile duct disorder called primary biliary cirrhosis — can result in cirrhosis.

Is portal hypertension the same as esophageal varices?

Esophageal varices are the major complication of portal hypertension. It is detected in about 50% of cirrhosis patients, and approximately 5–15% of cirrhosis patients show newly formed varices or worsening of varices each year.

Why does cirrhosis cause portal hypertension?

Your body carries blood to your liver through a large blood vessel called the portal vein. Cirrhosis slows your blood flow and puts stress on the portal vein. This causes high blood pressure known as portal hypertension.

What is the life expectancy of someone with esophageal varices?

Varices recurred in 78 patients and rebled in 45 of these patients. Median follow-up was 32.3 months (mean, 42.1 months; range, 3–198.9 months). Cumulative overall survival by life-table analysis was 67%, 42%, and 26% at 1, 3, and 5 years, respectively.

How long do you live with portal hypertension?

These complications result from portal hypertension and/or from liver insufficiency. The survival of both stages is markedly different with compensated patients having a median survival time of over 12 years compared to decompensated patients who survive less than 2 years (1, 3).
