Examination of the Neck Veins

The examination of the neck veins is a standard clinical procedure performed to evaluate right atrial pressure and to estimate a patient's intravascular volume, particularly in those presenting with dyspnea, edema, or hypovolemia. In individuals experiencing dyspnea or edema, it is essential to assess the venous pressure and conduct the abdominojugular reflux test at the bedside. An elevated venous pressure or an abnormal result from the abdominojugular reflux test strongly indicates the presence of heart disease, such as left or right ventricular failure. Conversely, if both the venous pressure and the abdominojugular reflux test results are normal, it suggests that the dyspnea or edema is likely not caused by heart disease, but rather by an alternative condition such as pulmonary, liver, or kidney disease. Anatomically, the neck, or jugular, veins comprise external and internal veins that collect blood from the brain, face, and neck, ultimately draining into the brachiocephalic veins.
