Oh for sure the procedure is under general anesthesia. It was very quick (perhaps an hour) however I waited in the ER to be admitted the night before so it was performed the following day. Why did I go to the ER?....I was instructed to go by the radiologists because my scan showed that the SDH was not being reabsorbed as was expected after the diagnosis. My assigned neurosurgeon also was labeled an "expert" in MMA procedures. I was released the following day. One thing I will advise though is to really rest after this procedure. I did not, - While I was advised to resume my daily routines. I would strongly recommend to allow your body some slack to work on reabsorbing the current SDH. The MMA does stop the blood flow, but my POV is give it some time, and take it easy. Hope this helps. Please reply if I can be of any help further. All the best.

I had an emergency MMA because my 4th CT scan showed increased beeding. I had the scan at 10 am, was in my car driving home and was called by my Neurosurgeon to go directly to the ER! There was no anesteheadiologist available that day so I opted to be awake during the procedure. I had heavy pain meds in my IV. It took about an hour, was not painful and I was in the Neuro intensive care unit over night. I did have a head ache but not terrible. The pains on that side of my head continued for about 2 weeks (and I had sore teeth on that side of my mouth off and on during that time - maybe due to a nerve being effected during the procedure?). It's beeen almost 6 weeks and I am pain-free. Another CT scan is scheduled for next week.
