Main complications and causes of mortality
Complications of liver cirrhosis determine the severity of the patient's condition and directly lead to fatal outcomes. Key life-threatening conditions include:
- Liver failure.
- Hepatic encephalopathy and its extreme degree — coma.
- Massive hemorrhages. Most commonly, the source is varicose veins of the esophagus, stomach, or intestines.
- Thrombosis in the portal venous system.
- Hepatorenal syndrome.
- Development of hepatocellular carcinoma (HCC). Transformation into cancer, for example, in alcoholic etiology, occurs with a frequency of 5–15%.
Separately, infectious complications are distinguished, which are especially characteristic of alcoholic liver disease. These include pneumonia, sepsis, and spontaneous bacterial peritonitis (arising against the background of ascites). It is precisely hemorrhages, coma, thrombosis, and secondary infections that form the main mortality structure in this disease.
Morphological markers of process activity
Disease activity is assessed by clinical, biochemical, and histological criteria. It is important to remember that any activation of the process inevitably leads to its decompensation. The morphological picture of the active phase is characterized by the predominance of destruction:
- Necrosis: a large number of bridging, confluent, spotty, and piecemeal necroses are detected in the tissue.
- Dystrophy: hepatocytes undergo pronounced hydropic and ballooning degeneration.
- Inflammation: focal or diffuse lymphohistiocytic infiltrates form. They are localized both inside pseudolobules and in fibrous septa.
- Structural remodeling: specific hepatocyte "rosettes" appear, hepatic trabeculae thicken as a result of regeneration. New connective tissue septa are formed, which additionally divide pseudolobules into smaller fragments.
Prognosis and survival
Prognosis depends directly on etiology, liver functional status, and the presence of complications. In general, 5-year survival is 70–75%, and functional compensation is possible even in advanced stages. However, with decompensation, only 11–40% of patients are alive at three years. The appearance of ascites limits life expectancy to 3–5 years.
Prognosis varies greatly depending on the cause of the disease:
- Viral hepatitis B (HBV): 5-year survival reaches approximately 55% (up to 70% in asymptomatic inactive course). The main causes of death are liver failure (80%) and HCC (40%). The addition of delta infection (HDV) drastically worsens the outlook.
- Viral hepatitis C (HCV): progression is slow, prognosis is often uncertain. Annual mortality is 2–5%, and tumor development rate is 3–4% per year.
- Alcoholic damage: average survival is five years. Complete abstinence can prolong life, but this effect is significant only in early stages, before the appearance of refractory ascites and bleeding.
Traditionally, cirrhosis is considered an irreversible condition, but there is evidence of possible regression of fibrous septa (particularly in hemochromatosis).
Briefly: answers to topical questions
What is the macroscopic picture of the liver in micronodular cirrhosis?
The macroscopic picture of the liver in micronodular cirrhosis depends on the stage of the disease. In early stages, the liver is enlarged, has a dense consistency and a fine-nodular surface. The nodules are no larger than 3 mm, bright yellow due to fatty degeneration, and separated by thin layers of grayish dense connective tissue. At the end-stage of the disease, the liver may decrease in size and acquire a brown-red color; nodule sizes vary from 3 to 10 mm.
How does a pseudolobule in cirrhosis morphologically differ from a normal hepatic lobule?
A pseudolobule in cirrhosis is surrounded on all sides by connective tissue, while the normal angioarchitecture is disrupted: the radial orientation of hepatic cords is lost, and the central vein within the nodule is absent or displaced to the periphery. Inside the pseudolobule, nodular regeneration of hepatocytes is noted; regenerating cells can be large and sometimes multinucleated.
What are the extrahepatic morphological manifestations of portal hypertension in cirrhosis?
Extrahepatic morphological manifestations of portal hypertension include changes in the spleen, fluid accumulation, and the development of venous collaterals.
- Ascites (ascites) — accumulation of fluid in the abdominal cavity.
- Congestive splenomegaly (splenomegalia) — a significant increase in spleen mass. Morphologically, cyanotic induration develops in it: follicles are atrophied, red pulp is sclerotic and congested, hemosiderosis and distension of sinusoids with blood are noted.
- Expanded anastomoses (anastomoses) — variceal dilatation of veins in the lower third of the esophagus and the cardial part of the stomach, dilatation of the hemorrhoidal venous plexus, as well as dilated veins of the anterior abdominal wall (caput medusae sign).
To remember the main complications, use the acronym HEB-PHC: Hepatic failure, Encephalopathy, Bleeding, Portal vein thrombosis, Hepatorenal syndrome, Cancer (HCC).
Class and exam questions
What do patients with cirrhosis most commonly die from?
The main causes of death are massive bleeding from varicose veins, hepatic coma, portal vein thrombosis, and secondary infections.
Can liver cirrhosis be reversed?
Traditionally, the process is considered irreversible. However, there is evidence of possible regression of fibrous septa in certain forms, for example, in hemochromatosis.
How does alcohol cessation affect the prognosis in alcoholic cirrhosis?
Complete abstinence can significantly prolong life, but only if it is initiated in early stages — before the development of bleeding and refractory ascites.
What indicates the morphological activity of cirrhosis?
Destructive changes predominate in the liver tissue: various types of necrosis, hydropic and ballooning degeneration, as well as the appearance of hepatocyte "rosettes" and new fibrous septa.
