Hi XXXXXXX,
Thank you for asking these questions. I like people who ask questions, as the answers may improve the quality of their and their family member's lives.
Regarding your current question, the complete blockage of left carotid reduces the blood supply to left side of brain. So, TIA and stroke can occur with complete blockage.
However, the stroke severity is less in your husband's case, as some amount of blood is reaching the left side of brain from the right carotid side due to collateral branches, as explained yesterday.
Please get back if any more queries are there.
Best wishes,
Dr Sudhir Kumar MD DM (Neurology)

Complete blockage did not occur after the stroke. If that had happened, he would have lost complete speech and would have had severe weakness of the right arm and leg, which did not happen.
This suggests that blockage of left carotid happened gradually over time, giving ample time for collateral branches to develop from right carotid and supply the left side of brain.
As you would expect, the supply from the right carotid through collateral branches can not be as good as direct blood supply from left carotid; hence, he developed minor stroke.
This condition can be well managed medically and if all precautions are taken (as mentioned yesterday), I don't expect any serious thing to happen.

how many times in a yearshould he take mri,ct angio ,lipid tests

Answered by Dr. Sudhir Kumar 1 hour later
If there are no symptoms, routine MRI and CT angio are not required.
Lipid profile may be repeated once in six months.
Simple- carotid doppler test- may be done to see the carotids and it may be repeated at six month intervals.
