In the somewhat rare instance a small blood vessel burst, which is also known as an aneurism, there is usually very little that can be done for the patient. The only corrective measure requires a surgical procedure, which must be done at the hospital. There is no on the scene treatment, including aspirin, that will effect the patient's outcome. However, aspirin can have a positive effect on the outcome of those who have clot related strokes, which is the vast majority. My deepest sympathy on the passing of your father.
