I just did a question and it totally contradicted what First Aid says. I want your opinions. Name the players and most commons. Here's a word bank to get you started:

anterior cerebral artery
middle cerebral artery
anterior communicating artery
posterior communicating artery
vertebral arteries
basilar artery

where did your question come from?

I've heard the most common site for hemmorhage from a berry aneurysm is anterior. Not sure if that correlates well with most common site of a non-ruptured aneurysm.

This is another list I had been taught:
Most common sites of aneurysm--
Anterior Communicating Artery (35%)
Posterior Communicating Artery (35%)
Middle Cerebral Artery (20%)


So, who knows?

Can't remember. Sorry. I'm confused either way though...

k.....internal carotid--> --> anterior cerebral---> anterior communicating.

Berry aneurysms occur at the bifurcation of the anterior communicating or at the anterior cerebral artery....

as a side note: ACOMM aneurysm is the most common in the Circle of Willis; it produces a bilateral lower quadrantanopia. (so it must be a problem of perfusion near the calcarine suclus).

PCOM aneurysm--> 2nd most common of the COW; produces a CN 3 palsy. So your eye will be laterally deviated (external strabismus due to lateral rectus)
