Intracranial Aneurysms: Treatment with Bare Platinum Coils—Aneurysm Packing, Complex Coils, and Angiographic Recurrence

Abstract

More angiographic recurrences are detected over time. Complex coils do not augment aneurysm packing. Packing is not related to protection against recurrence.

No advantage of time-of-flight magnetic resonance angiography at 3 Tesla compared to 1.5 Tesla in the follow-up after endovascular treatment of cerebral aneurysms

“…An aneurysm recurrence rate between 20% and 30% after endovascular treatment has been reported [3,4,14,15]. The re-treatment rate in the International Subarachnoid Aneurysm Trial (ISAT) study group was 17.4% [14].…”

Long-Term Follow-Up of 1036 Cerebral Aneurysms Treated by Bare Coils: A Multicentric Cohort Treated between 1998 and 2003

“…Results of these new devices, however, are sometimes disappointing, and it remains to be proved that modified coils provide better results. [24][25][26] One of the limitations in our study, which began in 1998, is the absence of an independent core laboratory to analyze our results. However, in each of the 5 participating centers in our study, the physician who collected and reviewed all of the aneurysms was independent of the treating physician.…”

Evaluation of angiographic computed tomography in the follow-up after endovascular treatment of cerebral aneurysms—a comparative study with DSA and TOF-MRA

“…A long-term follow-up is mandatory because there is a relevant rate of aneurysm recurrence of up to 30%, which does not always need retreatment, but, however, can be associated with a risk of rebleeding [3][4][5][6]. Many neurovascular centers perform a follow-up digital subtraction angiography (DSA) and a time-of-flight magnetic resonance angiography (TOF-MRA) at 3 to 6 months after treatment in order to continue with TOF-MRA alone, which has been shown to be sufficient in detecting recurrent aneurysms in the majority of the patients [7][8][9].…”
