Dear friend, welcome to HCM !
I read with concern the report you posted.
Your mother has a blood supply deprivation of the left sided brain structures involving a large area (fronto-temporo-parietal) causing the stroke
Many factors would determine the outcome and we need to know them all to comment on the likely outcome and costs.
She would need aspirin
on long term basis.
But if this large area of infarct swells up even with medical treatment (which does happen once in a while) and causes compression of the surrounding brain, these patients may need decompressive craniectomy
(skull cap removal) to relieve pressure in the skull.
This decision will depend on the GCS scale and repeat CT/ MRI
scan if needed. In large infarcts, aspirin may not be given.
She will need long ICU
and ward stay. Sometimes outcomes are grim and may result in demise.
Your doctor in India is the best judge to decide and a neurology and if needed, a neurosurgery opinion is must.
The costs in USA are at least more than 5 times here and India has excellent treatment facilities here for stroke management as is ours. (I manage strokes daily in a big tertiary care centre).
So, the decision is yours where to treat.
I hope to have satisfied your query well.
Please revert if you need any more help here.
Take care and please keep me informed of your progress.
I hope to have answered your query satisfactorily.
