Follow-up for Intracranial Aneurysms in Children

Frequency of Office Visits and Imaging

Vigilant follow-up is recommended in children after treatment of an intracranial aneurysm, since the annual risk of recurrence (2.6%) and the annual risk of de novo aneurysm formation (7.8%) are higher compared to adults (30, 58). In the absence of guidelines, the following recommendations are loosely based on the available literature:

  • Initial postoperative visit at 4–6 weeks: The first postoperative visit should be scheduled 4–6 weeks after treatment.
  • Annual visits: Annual visits and MRI scans including MR angiography are recommended, especially for patients with coiled aneurysms.
  • Angiography after treatment: DSA should be discussed at 1 and 5 years after treatment.
