What causes enlarged jugular vein?
Jugular vein distention may be caused by heart conditions and conditions that affect blood vessels including: Congestive heart failure (deterioration of the heart’s ability to pump blood) Constrictive pericarditis (infection or inflammation of the lining that surrounds the heart that decreases the lining’s flexibility)
Where does the blood flow from the jugular vein?
What is the jugular artery? What is the jugular artery? The internal jugular vein is formed by the anastomosis of blood from the sigmoid sinus of the dura mater and the common facial vein.

What will happen if a jugular vein is removed?
Removal of one jugular vein usually causes minimal or no problems. There are many other veins in the neck and the blood can flow back through them. There may be some temporary swelling, but this usually decreases after a couple weeks.
How do you assess JVD?
To check for JVD, position the patient supine with his head elevated at about a 45° angle. Then ask the patient to turn his head to one side, while you observe his neck, looking for a pulsation. Shining tangential light onto the neck may be helpful in visualizing a pulsation.
How deep in is the jugular?
