Hi,
Thank you for posting your query.
I have noted your symptoms and treatment received so far.
I think you are on correct treatment and
warfarin should be continued for long to prevent any brain
stroke.
You could see your
neurologist for review.
I do not think that a
bypass surgery is needed, as you are doing so well on medical treatment.
I hope my answer helps. Please get back if you have any follow up queries or if you require any additional information.
Wishing you good health,
Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology)
