Carotid bleeding

[Miracoli]

A pt comes to the ED and is bleeding profusely from a knife wound to the neck. A surgeon identifies the source of bleeding as from the common carotid artery. To control the bleeding, the surgeon can compress the carotid artery against the anterior tubercle of which of the following vertebra?
A) first cervical
B) second cervical
C) third cervical
D) fourth cervical
E) fifth cervical
F) sixth cervical

F. The carotid tubercle is at C6, along the same level as the cricoid cartilage.

Is there any good resource with random anatomy factoids like this?

Not sure. I just remember that from Big Moore (Clinically Oriented Anatomy).

I did a Google search for USMLE resources that mention the carotid tubercle, but besides the Kaplan Qbook, the only other review book I found was Orthopaedic Surgery Review: Q & A, and I don't think reading that would be the best use of time for Step 1 prep.

F is the answer.
You can compress the common carotid artery against the groove between the anterior (carotid)tubercle and vertebral body of C6 to control bleeding. It can also be used as a landmark for blocks(Supraclavicular brachial plexus blocks)
Yeah some anatomy Q are factoids but now you know it🙂
Thanks.

Artery connecting PCA to Sylvian artery should be posterior communicating arteries. Good picture but it was making me confused for a little bit.

You are right, sorry i have not seen that. I was focusing more in common carotid and C6 vertebrae. Thanks for noting that.
