Classifications
There are three common classifications to the branching pattern: [1]
- Normal (as below) – seen in ~ 70% of patients.
- Bovine arch – common origin of brachiocephalic and left common carotid artery – seen in approximately 15% of patients (more common in blacks)
- Left common carotid has its origin from the brachiocephalic artery proper, rather than from a common trunk – – seen in approximately 10% of patients (also more common in blacks)
There may be additional branches that arise directly from the arch. These include:
- Thyroidea ima artery, usually between the brachiocephalic and left common carotid
- Left vertebral artery, usually between the left common carotid and the left subclavian arteries.
- Rarely the right subclavian and right common carotid arise independently.
