The venous drainage of the head and neck occurs through a superficial and deep venous system. Both systems converge in the so-called venous angle (Angulus venosus) to form the brachiocephalic vein and empty into the superior vena cava.

Superficial Neck Veins
V. jugularis externa
- runs in the lateral cervical triangle covered by the platysma
- passes through the superficial lamina of the cervical fascia
- empties into the venous angle or previously into the V. jugularis interna and then into the V. cava superior
V. jugularis anterior
- usually runs on the M. sternocleidomastoideus
- empties into the venous angle or into the V. jugularis externa
-
Deep Neck Veins
Internal jugular vein
Origin
- originates intracranially through the confluence of the sigmoid sinus and inferior petrosal sinus
- begins as the so-called superior jugular bulb and passes through the skull base in the jugular foramen
Course
- runs together with the common carotid artery within the carotid sheath
- forms the brachiocephalic vein in the venous angle together with the subclavian vein and others
Tributaries cranial → caudal
- Superior ophthalmic vein
- Facial vein
- Retromandibular vein
- Pterygoid plexus
- Pharyngeal veins
- Lingual vein
- Superior and middle thyroid veins
- Sternocleidomastoid vein
Drainage area
- entire brain
- Face
- Thyroid gland
Subclavian vein
- Continuation of the axillary vein
- runs anterior to the anterior scalene muscle
- joins with the internal jugular vein at the venous angle and forms the brachiocephalic vein, which empties into the superior vena cava
Venous angle
Origin
- arises from the confluence of the subclavian vein and internal and external jugular veins
Location
- ventral to the anterior scalene muscle
- dorsal to the sternoclavicular joint at the level of the superior thoracic aperture
Tributaries cranial → caudal
- Subclavian vein
- External jugular vein
- Internal jugular vein
- left venous angle: Thoracic duct
- right venous angle: Right lymphatic duct
Drainage area
- all structures of the head-neck region
