I Had A CT Angiography For A Severe Headache .
Question: I had a CT angiography for a severe headache. Everything was normal except :
Right Posterior Cerebral Artery: Patent, mildly hypoplastic P1 segment.
&
Posterior communicating arteries: Patent on the right, Not seen in the left.
My physician ordered a Dopler, but they can't get me in until December.
My questions are: Is it careless of them to be so casual about potential non-patent blood flow in the brain? 2) What causes these anomalies and could degenerative problems in c3-c7 cause disrupted flow?

Brief Answer:
It is necessary to address correctly these problems.
Detailed Answer:
Hello and welcome to the " Ask A Doctor" service.
I have read your query.
About the mildly hypoplastic posterior cerebral artery, it should result in no serious problems since it is found to be mild, and there should be sufficient blood flow.
Absent posterior communicating artery on one side is a risk factor for significant ischemic stroke in the presence of the ipsilateral carotid artery occlusion.
So, measures should be undertaken to minimize the risk of stroke, for this purpose is necessary a correct control of blood pressure, blood thinners may be used (aspirin for example).
The ultrasound will give the necessary information about the patency of the carotid and vertebral arteries.
These anomalies are very likely to be genetic or developmental in origin and have been there probably since birth.
They are not related to spinal degenerative problems.
Please discuss with your Neurologist these issues.
Hope you found the answer helpful.
Let me know if I can assist you further.
