Hi, welcome to our site. I am Dr Saumya Mittal, MD. Read your query. That is a very significant question and i appreciate your problem. I will try my best to answer your query The point is that what you seem to have described is an infarct. The clot may arise from some place and lodge into the brain arteries. The clot may also develop into the brain per se. the problem with the brain ischemia is that most of the procedures have to be done within the first few hours. Roughly about 6-8 hours. So if it is beyond that, the procedure may not be too helpful. As for the cost it depends entirely on the treating hospital and the setup of the hospital. I hope this helps you. Inform the reports mentioned above/if any other so I can be of help further. I have given you the answer to the maximum considering the information provided. The results of the tests could further enhance my answer to you. Please do understand that some details could be extracted from a detailed history and examination. Please feel free to ask another query. I would be glad to help you. Looking forward to your return query with the details asked so that I can help you further. (If the answer has helped you, please indicate this) Best of luck.
