The anterior jugular vein varies considerably in size, bearing usually an inverse proportion to the external jugular. [1] Most frequently, there are two anterior jugulars, a right and left. [1] [4] However, there is sometimes only one. [1] A duplicate anterior jugular vein may be present on one side, which may cross over the midline.
Drainage Territories: Although these trunks generally drain the mediastinum, lungs, and associated structures, the specific regions of the thorax drained by each trunk can vary. This is particularly important in surgical settings, such as during lymph node dissections or in evaluating the lymphatic spread of thoracic cancers.
The internal jugular veins join with the subclavian veins more medially to form the brachiocephalic veins. Finally, the left and right brachiocephalic veins join to form the superior vena cava, which delivers deoxygenated blood to the right atrium of the heart. [2] The jugular vein has tributaries consisting of petrosal sinus, facial, lingual ...
They drain either to the inferior deep cervical lymph nodes or into the jugular trunk. [1] Most of these lymph nodes are situated deep to the sternocleidomastoid muscle, though some are not. [1] Some are situated anterior and some posterior to the internal jugular vein. They are also situated adjacent to the accessory nerve (CN XI). [2]
A Hickman line two-lumen catheter inserted on the patient's left side. Scars at the base of the neck indicate the venotomy site and insertion point into the left jugular vein. A Hickman line is a central venous catheter most often used for the administration of chemotherapy or
This leads to varices in the esophagus and stomach, which can bleed; B) a needle has been introduced (via the jugular vein) and is passing from the hepatic vein into the portal vein; c) the tract is dilated with a balloon; D) after placement of a stent, portal pressure is normalized and the coronary and umbilical veins no longer fill.
Just above the sternum the two anterior jugular veins communicate by a transverse trunk, the jugular venous arch (or venous jugular arch), which receive tributaries from the inferior thyroid veins; each also communicates with the internal jugular. There are no valves in this vein.
The pharyngeal veins commence in the pharyngeal plexus superficial to the pharynx. The pharyngeal veins receive as tributaries meningeal vein , and the vein of the pterygoid canal . The pharyngeal veins typically empty into the internal jugular vein (but may occasionally instead empty into the facial vein , lingual vein , or superior thyroid ...
