- Purpose There have been few reports on the endovascular
treatment of aneurysms arising from A1 due to their rarity.
We report the angiographic results, clinical outcomes, and
technical aspects of endovascular treatment for 13 A1
aneurysms in 12 patients.
Methods From January 2002 to November 2007, 12
patients (9 females and 3 males) with 13 A1 aneurysms
underwent endovascular treatment. Three of these patients
presented with subarachnoid hemorrhage, and 10 unruptured
aneurysms were detected in 9 patients. All of the
aneurysms were successfully treated with coil embolization.
Most of the aneurysms projected posteriorly (61.5%) and
were located in the proximal A1 segment (69.2%).
Procedural, clinical, and radiological follow-up data were
Results Procedure-related complications occurred in 3
patients (25%) and included 1 non-leaking aneurysmal
perforation and 2 thromboembolic events; none of them
were clinically significant. No bleeding or rebleeding
occurred during the follow-up period in this cohort of
Conclusions Endovascular coil embolization is an effective
treatment modality for A1 aneurysms. Tailored micro-catheter shaping according to aneurysm projection and
location is necessary. Long-term follow-up studies involving
a larger number of patients and further comparisons
with surgical data are needed.
