a patient has portal hypertension induced splenomegaly

In chronic liver diseases, splenomegaly and hypersplenism can manifest following the development of portal hypertension. These splenic abnormalities correlate with and have been postulated to facilitate the progression of liver fibrosis to cirrhosis, although precise mechanisms remain poorly understood.

How does splenomegaly cause portal hypertension?

Liver disease such as cirrhosis, or liver scarring, can cause the blockage of blood flow through the liver, thus causing blood to back up in the portal vein resulting in increased pressure or portal hypertension. As a result, the spleen becomes engorged with blood, leading to splenomegaly.

Why does portal hypertension cause splanchnic vasodilation?

The down-regulation of the mesenteric adrenergic system has been interpreted as a local consequence of portal hypertension that might contribute to aggravating splanchnic vasodilation, which is responsible for a generalized sympathetic overactivity, especially in muscles and kidneys.

Does portal hypertension affect blood pressure?

Portal hypertension is a leading side effect of cirrhosis. 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.Jan 3, 2020

What is the treatment for a swollen abdomen?

Common treatment includes diuretics (water pills), limiting salt in the diet, antibiotics (if infection is present), not to mention the avoidance of alcohol. If the patient does not respond to the common treatments, then the placement of a tube in the abdomen may be used to drain large amounts of fluid from the area.

What is the function of the spleen?

The spleen is an organ that is part of the lymph system. The spleen’s role is to filter blood and to maintain healthy red and white blood cells and platelets. To clarify, your spleen acts like a spongy filter for your blood.

Why does the spleen enlarge?

When the body is fighting these infections , the spleen works hard to produce antibodies against the infectious agent, leading to an increase in the number of splenic cells. This can ultimately cause enlargement of the spleen. Splenomegaly can also occur as a result of certain blood cancers, such as leukemias and lymphomas.

What causes a sickle cell?

Sickle cell disease, in which red blood cells can take the shape of a crescent, or a sickle, due to defective hemoglobin, can also cause splenomegaly. In sickled form, red blood cells can stick together and block the splenic capillaries, preventing blood flow out of the spleen and causing its enlargement.

What is the portal vein?

The portal vein, formed by the superior mesenteric and splenic veins, drains blood from the abdominal GI tract, spleen, and pancreas into the liver. Within reticuloendothelium-lined blood channels (sinusoids), blood from the terminal portal venules merges with hepatic arterial blood. Blood flows out of the sinusoids via the hepatic veins into ...

What causes hypertension in the liver?

Any condition or abnormality that changes the blood flow, and therefore the pressure within the vessels, can cause hypertension. The cause of the increased pressure in the portal venous system may be above the liver (suprahepatic), within the liver (hepatic) or below the liver (infrahepatic), and may include cardiac disease, hepatic vein thrombosis (Budd-Chiari syndrome), cirrhosis and arteriovenous malformations (AVMs) within the splenic vasculature.
