3.2. Liver + Biliary Tree Disease - Cirrhosis Flashcards
What is Liver Cirrhosis?
A Disease, usually following on from another Disease, which involves the Death of Hepatocytes
What can cause Liver Cirrhosis?
- Hepatitis (Alcoholic, B, C, D, Autoimmune)
- Non-Alcoholic Fatty Liver Disease
- Hereditary Conditions
a) Cystic Fibrosis
b) Wilson’s Disease - Primary Biliary Sclerosis
- Primary Scerosing Cholangitis
What are the Characteristic Features of Cirrhosis?
- Regenerating Nodules separated by Fibrous Septa
2. The Loss of Lobular Architecture within the Nodules
What causes the Characteristic Features of Fibrosis?
Necrosis of Hepatocytes
What is the Liver Architecture like in Cirrhosis?
Diffusely Abnormal, which interferes with the Function and Blood Flow
What are the 2 types of Cirrhosis?
- Micronodular
2. Macronodular
What are the features of Micronodular Cirrhosis?
- Regenerating Nodules which are less than 3mm in size
2. The Liver is involved uniformly
What are the features of Macronodular Cirrhosis?
- The Nodules are of Variable Size
2. Normal Acini may be seen within the Larger Nodules
What can cause Micronodular Cirrhosis?
- Ongoing Alcohol Damage
2. Biliary Tract Disease
What can cause Macronodular Cirrhosis?
Chronic Viral Hepatitis
What are the Clinical Features of Liver Cirrhosis?
- Ascites
- Portal Hypertension
- Variceal Bleeding
- Encephalopathy
- Clinical Signs
Why might Ascites occur during Liver Cirrhosis?
Due to the potential hepatocyte content leaking into the Peritoneum
Why might Portal Hypertension occur during Liver Cirrhosis?
Due to the Restricted Blood Flow
Why might Variceal Bleeding occur during Liver Cirrhosis?
Due to the potential rupture of Hepatic Blood Vessels, due to the Portal Hypertension
Why might Encephalopathy occur?
Due to the Liver not being able to appropriately deal with the Toxic Metabolites, and these effecting the Brain
