Hi Sir My Father Had Head Injury 3 Months Back

hi sir my father had head injury 3 months back and treated well, after 1 month of discharge ct scan showed increase in clot size and doctor told to stop ecosprin 75 mg. after 1 month again we took ct scan now the clot size is reduced from 17mm to 13mm. doctor told us to come after 1 month with ct scan again. we consulted another doctor he told us its better we go for bur hole surgery as it is risky for the patient. but my father is perfectly well now he is very active.
