What is the jugular vein distention position?

To properly evaluate jugular venous distension, the patient must be placed at a 45-degree angle, or slightly less. Visualization of the jugular veins is best done at an oblique angle, so sit beside the patient and elevate the head of the cot into a semi-Fowler’s position.

Where is the jugular vein and carotid artery?

neck

What is distended neck veins?

In patients with acute inferior-wall MI with right ventricular involvement, distention of neck veins is commonly described as a sign of failure of the right ventricle. Impaired right ventricular function also leads to systemic venous hypertension, edema, and hepatomegaly.

What causes jugular distension?

Where is the external jugular vein?

The external jugular vein begins at the level of the mandible and runs obliquely across and superficial to the sternocleidomastoid (see the image below).

What forms the internal jugular vein?

It is formed by the union of inferior petrosal and sigmoid dural venous sinuses in or just distal to the jugular foramen (forming the jugular bulb). It descends in the carotid sheath with the internal carotid artery. The vagus nerve (CN X) lies between the two.

How big is the jugular vein?
