Carotid Aneurysms

Carotid aneurysms are rare, occur in the midneck area, and manifest as pulsatile masses. Rupture is rare, but these aneurysms are a source of cerebral emboli. Carotid aneurysms must be distinguished from the much more common tortuosity and bending (kinking) of a carotid artery, which lacks clinical consequence. Kinking, usually with a strong pulse just above the clavicle, more often on the right side, is common among the elderly; it requires no treatment. Ultrasonography is useful in distinguishing kinking from aneurysmal dilation but is usually unnecessary. Surgical repair is usually indicated for carotid arterial aneurysms.
