hepatojugular reflux
Noun: - A physical examination sign: Hepatojugular reflux is a clinical sign characterized by the distention of the jugular veins in the neck when sustained pressure is applied to the liver or abdomen. This indicates increased pressure in the right side of the heart and is often associated with congestive heart failure.
This term is used exclusively in a medical context to describe a specific diagnostic finding during a physical examination. - The presence of hepatojugular reflux suggested the patient's heart failure was worsening. - To test for hepatojugular reflux, the physician applied firm pressure to the upper abdomen for 30-60 seconds while observing the patient's neck veins.
- "Positive hepatojugular reflux": This phrase is used to confirm the observation of the sign, indicating abnormal cardiac function.
- The physical exam was notable for a positive hepatojugular reflux and bilateral lower extremity edema.
- HJR: A common medical abbreviation for hepatojugular reflux.
- The chart note read: "HJR positive, consistent with volume overload."
- Jugular venous distention (JVD): A related sign of increased central venous pressure, of which hepatojugular reflux is a provocative test.
- Abdominojugular reflux: An alternative term for the same sign, emphasizing pressure on the abdomen rather than specifically the liver.
- Abdominojugular test: Another name for the maneuver used to elicit the sign.
- Positive abdominojugular reflux: A synonymous finding.
This term has only one specific meaning in medical diagnostics. It is not used in general language or in other technical fields. The sign is named for the liver (hepato-) and the jugular vein, with reflux indicating a backward flow of blood due to elevated pressure.
