So for the time being, I think I would opt for the endarterectomy if I had to give a choice. I know the minimal invasive option always sounds great. I think if you google carotid endarterectomy vs stenting , you will be presented with a lot of information.
I think medication will see you through for a long time yet, giving you lots of time to study this.
The recommended quidelines:
In individuals without symptoms and blockages of 60% or less, medical therapy alone is appropriate. This involves the use of an anticoagulant, which may include:
Aspirin, Coumadin (warfarin), etc.
Endarterectomy is three times as effective as medical therapy
alone in reducing stroke in individuals whose blockages are 70-95% and have
