Jugular vein reflux test

The jugular venous return test is an auxiliary examination method used to check whether the veins are normal. Diseases such as right heart failure, pericardial effusion, constrictive pericarditis, obstruction of blood flow in the portal and systemic venous system, and congestion of various organs in the abdominal cavity, especially liver and spleen. When these organs are oppressed, the blood that accumulates inside is forced to return, leading to a further increase in pressure in the right atrium, which hinders the return of blood to the superior vena cava and increases the jugular vein filling. Through this examination, the corresponding symptoms can be judged.
