Hepato-jugular reflux sign

The liver-jugular regurgitation examination is an auxiliary examination method for checking whether the blood vessels are normal. Hepatic jugular venous return in patients with right heart failure, such as pressing the enlarged liver, the jugular vein filling is more obvious, said the positive jugular venous return sign, is one of the important signs of right heart failure, may also be seen in the infiltration Exfoliative or constrictive pericarditis. The mechanism of the blood flow to the inferior vena cava and the right atrium is increased by pressing the liver of the blood stasis, but the right atrial blood stasis or the right ventricular diastolic is limited, and the blood volume cannot be completely received, and the jugular vein filling is more obvious. Basic Information Specialist Category: Cardiovascular Examination Category: Other Examinations Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: Normal jugular veins do not expand, or may have mild expansion at the beginning of the pressure, but quickly drop to normal levels. Positive: This sign is an important sign of right heart failure, cardiac tamponade, constrictive pericarditis, restrictive cardiomyopathy, and tricuspid stenosis. When the abdomen is pressed, the blood flow to the inferior vena cava and the right ventricle is increased. Due to right heart failure or right ventricular diastolic restriction, the right atrial pressure is increased due to blood stasis, and the right atrium cannot fully receive the refluxed blood. Causes an increase in jugular vein filling. Tips: Maintain a normal diet and schedule. Normal value Normal jugular veins do not expand, or may have mild expansion at the beginning of the pressure, but quickly drop to normal levels. Clinical significance Abnormal result This sign is an important sign of right heart failure, cardiac tamponade, constrictive pericarditis, restrictive cardiomyopathy, and tricuspid stenosis. When the abdomen is pressed, the blood flow to the inferior vena cava and the right ventricle is increased. Due to right heart failure or right ventricular diastolic restriction, the right atrial pressure is increased due to blood stasis, and the right atrium cannot fully receive the refluxed blood. Causes an increase in jugular vein filling. People who need to be examined: routine physical examination items, abnormal blood vessels. Positive results may be diseases: constrictive pericarditis, restrictive cardiomyopathy, tricuspid stenosis, esophageal varices and rupture of bleeding Forbidden before examination: Maintain a normal diet and schedule. Requirements for inspection: Closing when inspecting, suffocating, will affect the judgment of results. Inspection process Let the patient be in a semi-recumbent position, observe the jugular vein filling degree during calm breathing, and then press the palm with a fixed pressure to press the umbilical part of the patient's abdomen. If the patient's jugular vein filling degree increases, it is called liver-jugular venous return sign positive. It is said that the abdomen-jugular regurgitation sign is positive, suggesting that the liver is congested, which is one of the early signs of right heart dysfunction. Also seen in exudative or constrictive pericarditis. Or the patient is in bed, the head cushion is high, and the mouth is breathing, avoiding Valsalva's suffocating action. The examiner's right palm is lightly attached to the liver area and gradually pressurized for 10 seconds while observing the degree of jugular vein engorgement. Not suitable for the crowd Inappropriate people: severe blood vessels and heart failure. Adverse reactions and risks Nothing.
