    Transcript
    Now, we transition to the stellate ganglion. The clinical correlation here is going to be a stellate ganglion block. But first, we need to understand the relevant anatomy of a stellate ganglion. The stellate ganglion forms from fusion of the inferior cervical and the first thoracic sympathetic ganglia. This fusion is identified in the image. This area here represents the stellate ganglion. The stellate ganglion is located anterior to the transverse process of vertebra C7. However, in this illustration, it’s a bit inferior to that normal location. Anatomic variation is something that we expect. The next consideration with the relevant anatomy is that of the carotid tubercle. The carotid tubercle is identified in the image right in through here. A carotid tubercle is also known by its eponym, Chassaignac tubercle. The carotid tubercle is the anterior tubercle of the transverse process of cervical vertebra number VI. This is an important landmark in the performance of the stellate ganglion block because the physician performing this procedure will make the injection at this landmark superior to the stellate ganglion. Then the nerve blocking agent will diffuse and ultimately diffuse inferiorly and have its influence or its effectiveness at the level of the stellate ganglion. There are very important anatomic relationships in this area that the physician should be aware of. Not all of them really are identified in this slide. But you think about this area of the neck and what lies here, you would have your common carotid artery. You’d have your internal jugular vein. You can see brachial plexus elements right in through here. So, one has to have great skill and expertise in performing this clinical procedure. Now that we talked about the relevant anatomy of the stellate ganglion and how it’s used for the block, why would one...
