Abstract
SUMMARY: Cerebral aneurysms are treated to prevent hemorrhage or rehemorrhage. Angiographic recurrences following endovascular therapy have been a problem since the advent of this treatment technique, even though posttreatment hemorrhage remains rare. Notwithstanding its unclear clinical significance, angiographic recurrence remains not only a prime focus in the literature but also frequently leads to potentially risky retreatments. The literature regarding aneurysm recurrence following endovascular therapy, spanning 2 decades, is immense and immensely confusing. We review the topic of recurrence following endovascular treatment of cerebral aneurysms in an effort to distill it down to fundamental material relevant to clinical practice.
