The carotid sheath is an anatomical term for the fibrous connective tissue that surrounds the vascular compartment of the neck. It is part of the deep cervical fascia of the neck, below the superficial cervical fascia meaning the subcutaneous adipose tissue immediately beneath the skin.

The deep cervical fascia of the neck includes four parts:

The investing layer (encloses the SCM and Trapezius)
The carotid sheath (encloses the vascular region of the neck)
The pretracheal fascia (encloses the visceral region of the neck)
The prevertebral fascia (encloses the vertebral region of the neck)

Structure

The carotid sheath is located at the lateral boundary of the retropharyngeal space at the level of the oropharynx on each side of the neck and deep to the sternocleidomastoid muscle, extending from the base of the skull to the first rib and sternum.

Layers

The three major fascial layers in the neck contribute to the carotid sheath: the investing fascia, the pretracheal fascia, and the prevertebral fascia.

Relations

The cervical part of the sympathetic trunk is embedded in prevertebral fascia immediately posterior to the sheath.
