Portal Hypertension and Esophageal Varices — Symptoms and Causes
ثبت نشده
چکیده
The development of varices in the esophagus and the gastrointestinal tract is only one of the 3 complications caused by increased pressure within the portal system, the others being ascites and hepatic encephalopathy. All of these conditions are essentially brought about by diseases that impair the flow of blood through the liver such as in liver cirrhosis. The presence of collateral blood vessels in the portosystemic circulation allows for a normal blood flow into and out of the liver. However, these collateral do not hold blood well in times of increased portal pressure, making them vulnerable to massive dilatation and rupture.
