Karotissäcken

Karotissäcken is a term used in some contexts to refer to the sac or covering that encloses the carotid arteries. These arteries are major blood vessels that supply blood to the head and neck. The exact anatomical structure referred to as the "karotissäcken" can vary depending on the specific medical or anatomical literature being consulted. In some descriptions, it may refer to the fascial sheath that surrounds the carotid artery, internal jugular vein, and vagus nerve, collectively known as the carotid sheath. This sheath is a crucial anatomical landmark.

The carotid sheath plays a role in containing and supporting these vital neurovascular structures. It is formed from deep cervical fascia. Injuries to the carotid arteries can have significant consequences due to the critical blood flow they provide. The term "karotissäcken" is not a universally standardized anatomical term in all medical lexicons but is understood within specific regional or historical medical texts. Understanding the anatomy of the neck and the structures within the carotid sheath is fundamental for medical professionals, particularly surgeons and radiologists.
