Esophageal varices are the most common clinical manifestation of portal hypertension in patients with liver cirrhosis. It is known that once bleeding occurs in patients with varices the prognosis is extremely poor, with 30-50% of patients dying within 6 weeks of the first variceal hemorrhage.
The main symptoms and complications of portal hypertension include: Gastrointestinal bleeding: Black, tarry stools or blood in the stools; or vomiting of blood due to the spontaneous rupture and bleeding from varices. Ascites: An accumulation of fluid in the abdomen.Nov 16, 2017
The clinical manifestations of portal hypertension may include caput medusae, splenomegaly, edema of the legs, and gynecomastia (less commonly) (Figure 2). Caput medusae is a network of dilated veins surrounding the umbilicus.
The most common cause of portal hypertension is cirrhosis (scarring) of the liver.
What are the complications of portal hypertension? The complications of portal hypertension are the complications of liver failure. These include gastrointestinal bleeding from varices, ascites and hepatic encephalopathy. Splenomegaly can also cause anemia, low white blood cell counts, and low platelet counts.
With regard to the liver itself, causes of portal hypertension usually are classified as prehepatic, intrahepatic, and posthepatic.Nov 30, 2017

Overview. Variceal bleeding happens when large veins, often in the esophagus, get swollen and break open. It's caused by a condition called portal hypertension. Portal hypertension is high blood pressure in the veins that filter blood from the intestines through the liver (portal system of the liver).
Portal hypertension leads to the development of the hyperdynamic circulatory syndrome, characterized by decreased mean arterial pressure (MAP), decreased systemic vascular resistance (SVR) and increased cardiac index (CI).
The portal venous system carries capillary blood from the esophagus, stomach, small and large intestine, pancreas, gallbladder, and spleen to the liver. The portal vein is formed by the confluence of the splenic vein and the superior mesenteric vein behind the neck of the pancreas.
Abstract. Portal hypertension is a major complication of cirrhosis, and its consequences, including ascites, esophageal varices, hepatic encephalopathy, and hepatorenal syndrome, lead to substantial morbidity and mortality.Apr 1, 2019
Answer. Posthepatic causes of portal hypertension may include chronic right-sided heart failure and tricuspid regurgitation and obstructing lesions of the hepatic veins and inferior vena cava. The latter conditions, and the symptoms they produce, are termed Budd-Chiari syndrome.Oct 15, 2020
Portal hypertension occurs when the blood pressure in the portal vein exceeds 10 millimeters of mercury (mm Hg) . The portal vein carries nutrient-rich blood from the stomach, spleen, pancreas, and other digestive organs to the liver.May 11, 2020
