Venous malformation between the external and internal jugular vein characterized by nonfluctant, painless, and nonpulsatile swelling on the right side of his neck while the individual was singing was reported in a 45-year-old man. Interestingly, there was no skin lesion observed on his neck. The swelling increased in size when the patient was shouting (Valsalva maneuver) and diminished in size ...

The study investigated the effect of angular position head on blood flow in jugular vein giraffes. considered is elastic and collapsible such that its cross-sectional area not uniform. Transmural pressure causes to move along vein. Mathematical equations describing were developed, was be inclined at an angle φ horizontal. A finite-difference scheme used solve motion for flow. results are presen...

The estimation of central venous pressure (CVP) by inspection of the neck veins is regarded as a quintessential example of effective bedside cardiovascular examination because it is virtually cost-free and requires minimal time and no equipment. In the upright position, venous drainage from the head occurs primarily through the vertebral veins, allowing the jugular vein to act as a manometer, “...
