[/INST] Hi, Thanks for writing in. It is important to know complete details before giving an opinion on a surgery of the brain. A blood clot in any place within the brain should be observed carefully. The first step is to see that the clot is not growing in size. For this one or more brain scans are required. Then the size of the clot is to be discussed. The location is important because in some places even a small clot can be risky and in other places a moderate sized clot will not be a serious concern. I do not understand completely regarding compression of nerve whether it is one nerve or a particular area. It will help if you can upload scan images and reports to understand the brain compression and clot location completely. Surgery in such cases are risky but if the patient is in a pre coma stage and not responding to commands properly then a surgery can be life-saving. If required you can take another opinion by consulting a different neurosurgeon by taking scan reports and discussing the problem. </s>
