The conversation between human and AI assistant.
[|Human|] Hi....... do you know if there is a treatment or even a surgery that can be done, when one is told by a physician that she has one artery in the neck that is completely disappeared, (however formed other little veins in order to let blood flow up to the brain).....and the other artery is blocked at 98%! This is supposedly not curable.....
[|AI|]  Hello, There is no treatment for the totally occluded artery. Regarding the other carotid artery, it is necessary to perform surgery (endarterectomy) or put a stent, in order to prevent possible stroke, which would be devastating with this situation. For this reason, I recommend consulting with a vascular surgeon as soon as possible.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
