Positive hepatojugular reflux is found in all of the following conditions except aEUR’
**Core Concept**
Positive hepatojugular reflux (HJR) is a clinical sign where an increase in jugular venous pressure (JVP) is observed upon compression of the liver. This sign is indicative of right-sided heart failure or increased intra-abdominal pressure.
**Why the Correct Answer is Right**
The mechanism behind positive HJR involves the transmission of increased intra-abdominal pressure to the thoracic cavity, thereby increasing the pressure in the jugular veins. This can be seen in conditions where there is an increase in intra-abdominal pressure, such as ascites or liver cirrhosis with portal hypertension. Right-sided heart failure can also lead to positive HJR due to the inability of the right ventricle to handle the increased venous return.
**Why Each Wrong Option is Incorrect**
**Option A:** This condition is a common cause of positive HJR due to increased intra-abdominal pressure.
**Option B:** Liver cirrhosis with portal hypertension is another condition where positive HJR is often observed.
**Option C:** This condition can also lead to positive HJR due to the increased pressure in the jugular veins.
**Clinical Pearl / High-Yield Fact**
It is essential to note that a negative HJR does not rule out right-sided heart failure, and other clinical signs should be considered in conjunction with this finding.
**Correct Answer:** D
