Anatomy of Veins of Neck in a Nutshell


Sternocleidomastoid: divides the region into 2 triangles

  • From sternum/clavicle to insert at mastoid bone
  • Creates large posterior triangle
    • External jugular vein goes into the medial/inferior portion to join the internal jugular vein
    • Cranial nerve XI (accessory nerve) passes across the middle
  • Anterior triangle
    • Anterior jugular vein drains this triangle
    • Venous drainage may be variable (pass deep/superficial to SCM)

Veins of the head/neck

  • Retromandibular vein
    • Vein courses posterior to mandible
    • Unpaired (no artery)
    • Formed by maxillary veins (usually 2) and the superficial temporal vein
      • Superficial temporal vein descends along lateral side of head and joins with 2 maxillary veins to form the retromandibular vein →
      • From this point, it is joined by posterior auricular vein to form the external jugular vein
      • External jugular vein will then join with internal jugular vein
    • Difficult to find until remove the mandible
  • Internal jugular vein
    • Right beneath the SCM & deep to investing fascia
    • Contained within carotid sheath
    • Inferior bulb of the internal jugular vein
      • Slight dilation of the vein
      • At the inferior part of the vein
      • Contains a valve that is positioned in such a way that it prevents the backflow of blood into head/neck.
  • The venous channels in the head with the exception of the inferior bulb have no valves.
    • Clinically relevant: hypertension may lead to swollen veins
    • Spread of infection/thromboses → from face to deeper areas/the brain
    • Above the corner of the mouth: infection more likely to go to the brain
  • Facial vein
    • Drains the face in many patterns
    • Paired with facial artery
    • Drains into external jugular through superficial branch
    • Also has deep branches on inside of mandible → drain to internal jugular
    • Thus, as this vein reaches corner of mandible, some drainage is to internal jugular, some is to external jugular.
    • Facial vein may hook up with retromandibular as well
  • Pathways:
    • Superficial + maxillary = retromandibular vein
    • Posterior auricular + retromandibular = external jugular vein
    • External jugular + internal jugular = still internal jugular
      • Occurs right near jugular bulb
      • Still have short segment before union with subclavian vein
      • External jugular vein cuts across the SCM and into the posterior triangle.
      • Occasionally have more than one External jugular vein.

​

Mnemonic of External jugular Vein Tributaries

  •  “PAST”
    • P: posterior external jugular vein
    • A: anterior jugular vein
    • S: suprascapular vein
    • T: transverse cervical vein
