carotid artery blockage

I am sorry to hear about wife's problems.  ((((((((Hugs to her ))))))))).

Carotid angioplasty is often combined with the placement of a small metal coil called a stent in the clogged artery. The stent helps prop the artery open and decreases the chance of it narrowing again. Did your wife have a stent placed ?  If not I would discuss this with her Dr. and if you are not satisfied with this Cardiologist please do seek out a second opinion. 

Keep us posted on how she is doing.

Blessings,
