The internal jugular vein is a paired jugular vein that collects blood from the brain and the superficial parts of the face and neck. This vein runs in the carotid sheath with the common carotid artery and vagus nerve. It begins in the posterior compartment of the jugular foramen, at the base of the skull.
The jugular veins are veins that take blood from the head back to the heart via the superior vena cava. The internal jugular vein descends next to the internal carotid artery and continues posteriorly to the sternocleidomastoid muscle.
Catheter placement in one of the big veins (Subclavian vein, Internal jugular vein or femoral vein) is routinely done to monitor central venous pressure (CVP), to administer long term intravenous medication and parenteral nutrition in critically sick patients. The subclavian vein is the preferred choice for this purpose because it is most ...
The carotid sheath is a condensation of the deep cervical fascia [1]: 578 enveloping multiple vital neurovascular structures of the neck, [2] including the common and internal carotid arteries, the internal jugular vein, the vagus nerve (CN X), and ansa cervicalis. [1]: 578 [2] The carotid sheath helps protects the structures contained therein. [2]
The triangle of Farabeuf is bounded by the internal jugular vein (posterior), common facial vein (anterior-inferior) and hypoglossal nerve (anterior-superior). The jugulodigastric lymph node is commonly found within these boundaries, and drains the pharyngeal tonsil. The triangle had surgical significance in the late 19th century but now serves ...
The patient is positioned at a 45° incline, and the filling level of the external jugular vein determined. [1] The internal jugular vein is visualised when looking for the pulsation. In healthy people, the filling level of the jugular vein should be less than 4 centimetres vertical height above the sternal angle. [2]
The first sign of a malignancy, especially an intra-abdominal one, may be an enlarged Virchow's node, a lymph node in the left supraclavicular area, in the vicinity where the thoracic duct empties into the left brachiocephalic vein, right between where the left subclavian vein and left internal jugular join (i.e., the left Pirogoff angle).
The internal carotid venous plexus is a network of veins surrounding the internal carotid artery as it passes through the carotid canal. [2] The plexus interconnects the internal jugular vein (extracranially) and cavernous sinus (intracranially).
