Hi,What would be the cause of the posterior communicating arteries being absent or tiny?Thanks.

Hello My name is***** will try my best to help you today.

It would likely be congenital, somebody would be just born with it.

Thank you, ***** ***** Does this mean that somebody with no posterior communicating arteries would be reliant on one artery, should the other be blocked? Thanks.

If other is block, they would rely on one artery.

The area supply would be supply by anastomosis or it would infarct.

Would you kindly give 5 star rating to this consult. It would be highly appreciated.

if say one of the vertebral arteries was fully blocked. If anything should happen to the other vertebral artery, the carotid arteries could not be relied on?

Yes, if one artery is block, area supply woudd be infarcted.

Are there any preventative medicines to prevent the other artery blocking?

Would statins prevent this?
