Delayed recanalization of brain arteriovenous malformation after complete obliteration by endovascular embolization
Delayed recanalization of bAVMs after angiographically complete endovascular obliteration is rare but significant. Vein- or artery-cast mismatch and residual hematoma may increase recurrence risk. Long-term imaging surveillance is advised, particularly when vessel-cast correspondence is imperfect. These findings underscore the need for tailored follow-up protocols with patients with embolic cast mismatch to reduce recurrence risk.
