This study evaluated late recanalization rates of brain arteriovenous malformations (bAVMs) after complete endovascular treatment in a cohort of 42 adult patients. The retrospective cohort study found that 90.5% achieved complete obliteration, with a late recurrence rate of 9.5% detected at 5- and 6-year follow-ups. A systematic review of 19 patients showed no late recurrences.
Key findings
- 90.5% of patients achieved confirmed complete obliteration after endovascular treatment.
- Two late recurrences (9.5%) were detected at 5- and 6-year follow-ups.
- The systematic review found no late recurrences in 19 patients with a mean follow-up of 20.8 months.
Why it matters
Understanding late recanalization rates is crucial for managing bAVMs post-treatment. This study highlights the importance of long-term follow-up to ensure complete obliteration and to identify potential recurrences.
