All of the following are true about chronic venous congestion of liver except
**Core Concept**
Chronic venous congestion of the liver occurs due to increased pressure in the hepatic veins, leading to **liver congestion** and potentially **cirrhosis**. This condition is often caused by **right heart failure** or **constrictive pericarditis**. The increased venous pressure leads to **hepatomegaly** and **ascites**.
**Why the Correct Answer is Right**
Since the correct answer is not provided, let's discuss the general effects of chronic venous congestion on the liver. The increased venous pressure causes **centrilobular necrosis**, leading to **fibrosis** and potentially **cirrhosis**. The liver becomes congested with blood, resulting in **hepatomegaly**.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option text, it's challenging to provide a detailed explanation. However, any option stating that chronic venous congestion leads to immediate **liver failure** might be incorrect, as the process is gradual.
**Option B:** Similarly, without the text, it's hard to comment, but if an option suggests that **left heart failure** is a common cause, it might be misleading, as **right heart failure** is more commonly associated with this condition.
**Option C:** If an option claims that **jaundice** is a rare symptom, it could be incorrect, as **jaundice** can occur due to the liver's decreased ability to process **bilirubin**.
**Option D:** Without the text, it's difficult to assess, but if an option states that **liver function tests** are always normal, it would be incorrect, as these tests can be abnormal due to the liver's decreased function.
**Clinical Pearl / High-Yield Fact**
Chronic venous congestion of the liver is a serious condition that can lead to **cirrhosis** and **liver failure** if left untreated. It's essential to identify and manage the underlying cause, such as **right heart failure**, to prevent long-term liver damage.
**Correct Answer:** D. Chronic venous congestion of liver is characterized by sinusoidal dilatation.
