My father became symptomatic with left leg weakness and numbness, and subsequent diagnosis of subdural hematoma. We learned that likely a blow to the head caused a slow bleed, and probably 4-5 months earlier, as the blood was old and the consistency of motor oil. When blood like this ages, it expands, and eventually causes symptoms. He had developed a mid-line shift, and on CT, it literally looked as though 1/3 of his brain was blood. He was given the option of waiting to see if the blood good gradually be resorbed, or proceed with burr-hole surgery. Since he lived alone, an was basically at risk of falling because his symptoms had quickly appearred and worsened, he elected to have the burr-hole surgery. We were told that he would have to lie flat for 48 hours after the surgery, to allow gravity to help the brain to move back into place once the blood was drained out. He did so well after the surgery that he was sitting up eating breakfast the next morning. I questioned several people about this, and was told that he was doing so well the doctor changed the orders. I believed at the time this was a mistake and the doctor should not have rushed through this part of the post op protocol. But, my father quickly became asymptomatic, was walking and energetic, and looking forward to getting back to his routine. He was in the hospital for 6 days, then he went to rehab for 10 days. It was supposed to be 7 days in the hospital and 14 days in rehab...because the first 3 weeks after surgery is considered a 20% risk of bleeding due to the riskiness of the surgery. He excelledin rehab, and actually enjoyed it. When the PT asked him to do 10 reps, my dad did 20 reps. I was very proud of him. The last couple of days in rehab, he seemed a little confused, and his dreams seemed real to him. His first afternoon home, he wanted to go to the bank and Post Office, and lunch out. His second day home was calm and just stayed home. His 3rd morning, he went to a neighbors for coffee, had a visior bring him soup for lunch, and then he went to his home office to check email. Something happened, and he must have known something was going wrong in his head. He had braced himself in his chair with both hands grasping a walking stick. The coroner said he had had a hemorrhage most likely due to the surgery which carried a risk of bleeding. We found an empty glass of what was red wine from the night before, and I wonder if that contributed to the bleeding...he was not told he could not have that. He refused to let us stay with him, because he was doing so well. My point in telling you all this is that the burr hole surgery has risks because of the drilling through the many blood vessels, and when a patient may be confused due to the blood or trauma of the blood, they may not be cautious or do those preventative things to be safe. There are real risks with this procedure,but when symptomatic, there may be no other choice. All the best to you, and hope you can wait it out until it just disappears.
