Not a simple answer I am afraid.
First, I assume you had NO fits - if you did, you will have the 'epilepsy' issue, even though it wasnt epilepsy
Next consideration is how much bleeding you had, WHERE, and from what. I suspect the doctors will want to know more about the number of coils, the percentage of the defect filled and the result of subsequent scans. They will want to know what, if any, deficit you had (weakness, power loss, speech. consciousness etc) and it resolution. Personally I would want details of the type of coil, any glue or beads used etc
So I would recommend you get your FULL notes from the hospital including ALL scans (original pictures and reports), all medical notes, letters, anaesthetic charts and operation sheets together with observation results. and then ask the regulator.
Good luck
