Carotid Tubercle

Chassaignac tubercle (or the carotid tubercle) is the name given to the anterior tubercle of the transverse process of the sixth cervical vertebra, separating the carotid artery from the vertebral artery and against which the carotid artery may be compressed by the finger.

It is named for Charles Marie Édouard Chassaignac, French doctor. Applied aspect-in case of supraventricular tachycardia,the carotid artery can be massaged against this tubercle to relieve the symptoms.

The Chassaignac tubercle is used as a landmark by anesthesiologists for local anesthesia of the brachial plexus and the cervical plexus using the supraclavicular approach.
