Description
Estimated cost for Jugular Venous Ultrasound at general public hospitals in China is about ¥140-280, and at Grade 3A hospitals about ¥200-350, varying by hospital tier and region.
Main Uses
The main clinical uses of jugular venous ultrasound include assessing central venous pressure, evaluating for deep vein thrombosis, guiding central venous catheter placement, and diagnosing conditions affecting venous return. It is particularly useful in cardiology, critical care, and emergency medicine settings.
Normal Range
The normal range for internal jugular vein (IJV) diameter is typically less than 1.3 cm when the patient is in a supine position. Blood flow velocity should be smooth and unidirectional, with no significant turbulence or reflux. The IJV should collapse more than 50% during a sniff test or Valsalva maneuver.
Low Values - Possible Causes
Possible causes of low values include dehydration, hypovolemia, or conditions that reduce venous return such as heart failure or constrictive pericarditis. Other reasons may involve external compression or obstruction of the vein.
High Values - Possible Causes
Possible causes of high values include increased central venous pressure due to right-sided heart failure, tricuspid regurgitation, or pulmonary hypertension. Obstruction of the superior vena cava, volume overload, or chronic obstructive pulmonary disease (COPD) can also lead to elevated IJV measurements.
