Mar 15, 2011 · There are several complications of Portal Hypertension (PH), including one of the most precarious side effects called Esophageal Varices (covered in a previous post), and of lesser degrees are the conditions of ascites, and splenomegaly . Ascites takes place when excess fluid accumulates between the lining of the abdomen and abdominal organs.
A patient has portal hypertension-induced splenomegaly. Which lab value would the healthcare professional associate with this condition? a. Low white blood cell count b. Low platelet count c. High red cell count d. High hemoglobin and hematocrit ANS: B Thrombocytopenia (decreased platelet count) is the most common manifestation of congestive splenomegaly and can …
Normal portal vein pressures range from 5–10 mm Hg. The term portal hypertension refers to elevated pressures in the portal venous system. Venous pressure more than 5 mm Hg greater than the inferior vena cava pressure is defined as portal hypertension. Clinically it may be difficult to detect portal hypertension until pressures are much higher.
There are several other causes to splenomegaly which include diseases of the blood, liver, cancers, and infections but in the case of PH sufferers the cause is clotting to the portal and splenic veins.

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.
Portal hypertension is a pressurein the portal venous system that is at least 5 mm Hg higher than the pressure in the inferior vena cava. This increased pressureresults from a functional obstruction to blood flow from any point in the portal system's origin (in the splanchnic bed) through thehepatic veins (exit into the systemic circulation) or from an increase in blood flow in the system.
Cirrhosis is the most common cause of portal hypertension, and chronic viral hepatitis C is the most common cause of cirrhosis in the United States. Alcohol-inducedliver disease and cholestatic liver diseases are other common causes of cirrhosis. Less common causes include hemochromatosis, alpha 1-antitrypsin deficiency,drug-induced liver disease, and (in Eastern countries) hepatitis B. Portal hypertension is considered an advanced complication of cirrhosis. Once it has developed, theterm "decompensated cirrhosis" is used (Figure 5).
The aim of surgical shunting in portal hypertension is threefold: 1) to reduce portal venous pressure, 2) to maintain hepatic and portal blood flow, and 3) to try toreduce or not complicate hepatic encephalopathy ( Figure 16). Currently, there is no procedure that reliably and consistently fulfills all of these criteria.
Venous pressure morethan 5 mm Hg greater than the inferior vena cava pressure is defined as portal hypertension. Clinically it may be difficult to detect portal hypertension until pressuresare much higher. There are many causes of portal hypertension including etiologies above the liver, within the liver, and below the liver.
Clinically it is used toassess the efficacy of pharmacological agents or shunting procedures. Most approaches to portal pressure measurement are relatively invasive, with the exception of newer endoscopic techniques.
Endoscopy is the standard diagnostic approach in patients with acute gastrointestinal hemorrhage after initial resuscitation. In most patients with cirrhosis (60–80%)bleeding is related to esophageal varices. In addition to making a definitive diagnosis, endoscopic therapy may be indicated for bleeding. Endoscopic examinationmay require endotracheal intubation in patients who have significant alteration in mental status as a result of severe hepatic decompensation.
Complications secondary to portal venous hypertension can be life threatening and are often the main indication for transplantation in patients with advanced liverdisease. Although there are several collaterals between portal and systemic venous circulation, those at the junction of the stomach and esophagus are particularlyimportant. The dilated portosystemic collaterals at the junction of the stomach and esophagus are termed varices (Figure 20).
Pressure measurement of the portal system is possible, but it is invasive and usually not practical. Portal hypertension is a term for elevated pressures in the blood vessels that drain the intestinal tract and spleen into the liver (portal circulation).
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, ...
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.
Gastrointestinal bleeding with a low platelet count may be the first symptom of portal hypertension. Depending on the severity of liver disease, symptoms may also include ascites (fluid collection in the abdominal cavity), jaundice, hepatic encephalopathy, coagulopathy (slow clotting), or spider angiomata.
No . Portal hypertension is the result of structural changes within the liver that cause increased resistance in blood flow and increased pressure within the vessels. Cirrhosis is a chronic degenerative disease of the liver in which the organ becomes fibrotic with changes in the cells and connective tissue.
These increased pressures lead to dilations of the vessels called varices. Depending on the severity of liver disease and/or portal hypertension, varices may develop in the esophagus and in the stomach. Varices are blood vessels that have dilated due to higher pressure.
It is performed as soon after an upper GI bleed as possible, ideally within 12 hours or when the patient is stabilized. Varices are visible in the esophagus as long bluish bulging columns along the surface of the esophagus.
Testing. If confirmation of splenomegaly is necessary because the examination is equivocal, ultrasonography is the test of choice because of its accuracy and low cost. CT and MRI may provide more detail of the organ’s consistency. MRI is especially useful in detecting portal or splenic vein thromboses.

CT and MRI may provide more detail of the organ’s consistency. MRI is especially useful in detecting portal or splenic vein thromboses. Nuclear scanning is accurate and can identify accessory splenic tissue often found after splenectomy due to "work hypertrophy" of overlooked splenules or fragments released from a fractured spleen at the time of surgery. Occasionally, multiple spleen remnants can be found throughout the abdomen, often embedded in the neighboring pancreas, a condition called splenosis.
Splenomegaly is almost always secondary to other disorders. Causes of splenomegaly are myriad, as are the many possible ways of classifying them (see table Common Causes of Splenomegaly ). In temperate climates, the most common causes are. Connective tissue disorders. Lymphoproliferative disorders.

However, splenomegaly itself may cause early satiety by encroachment of the enlarged spleen on the stomach. Fullness and left upper quadrant abdominal pain are also possible. Sudden, severe pain suggests splenic infarction. Recurrent infections, symptoms of anemia, or bleeding manifestations suggest cytopenia and possible hypersplenism.
The sensitivity for detection of ultrasound-documented splenic enlargement is 60 to 70% for palpation and 60 to 80% for percussion. Up to 3% of normal, thin, people have a palpable spleen. Also, a palpable left upper quadrant mass may indicate a problem other than an enlarged spleen such as a hypernephroma.
Also, a palpable left upper quadrant mass may indicate a problem other than an enlarged spleen such as a hypernephroma. Other helpful signs include a splenic friction rub and shoulder pain that suggest splenic infarction as well as epigastric or splenic bruits that may occur due to increased blood flow.
