Declarations
:
: The patients were offered the possibility of follow-up DSA imaging after information regarding the possibility of AVM recurrence and its implications. This was done according to the Department’s new policy and not as part of a scientific study. Afterward, the hospital administration research approval was obtained for the retrospective secondary scientific use of the data as per Finnish legislation. According to current Finnish law, ethics committee approval is not required for the secondary use of existing clinical registry data.
