Carotid Duplex

I asked once before about my 74 y.o father with recurrent
stroke. A recent carotid doppler shows: left ICA totaly occluded.
Right ICA 50% narrowed. Left vertabral reversed. Right Vertabral
patent. He had a stroke caused by the L ICA occluding in
2000, from which he was making a good recovery; but recurrent
events are ruining him. His Neuro has done an MRI/MRA, but we
haven't been back yet. She seems interested in the Endarterectomy
but thinks because of the L ICA it would be high risk.
1) How does an artery become reversed and can you fix it.
2) Is the surgery worth the risk for the right ICA
3) as he only has one and a half out of four vessels would
stroke. A recent carotid doppler shows: left ICA totaly occluded.

Please keep in mind I have not seen your father's films or dopplers nor have I examined him. Thus it is not fair to your father and your family to base any major clinical decision such as need for surgery on my comments. Having said that:
1)I'm not quite sure what you meant by reversed. Need more details.
2)It will be a risky surgery. and unless the right side is symptomatic meaning he's had a stroke on the right brain, then the risks may not outweigh the benefits. What's important is how his intracranial circulation is, meaning can the other vessels supply the left side of the brain through other channels (collateral vessels)?
3)your question is cut off
