Abstract

Purpose: This study is an overview of the clinical and angiographic outcomes of patients who undergo treatment for distal anterior cerebral artery aneurysms.

Materials and methods: Between January 2009 and March 2012, 444 cerebral aneurysms were treated using endovascular coil embolization at our institute. Among them, 217 aneurysms were followed-up with angiography at least six months later. Of these, there were 16 distal anterior cerebral artery (ACA) aneurysms in 16 patients. We conducted a retrospective review of clinical and radiological follow-up results of all patients with distal ACA aneurysms. The clinical and angiographic outcomes were assessed using the modified Rankin scale (mRS) and the Raymond classification scale, respectively.

Results: The mean age was 54.7 ± 10.2 years (41-75 years). The mean follow-up period was 20.6 ± 9.64 months (6-37 months). Three patients presented with acute rupture. The average aneurysm size was 4.98 ± 1.39 mm (3.0-8.1 mm), and eight of 16 aneurysms (50%) had aspect ratios < 2.0. All 16 patients presented with complete obliteration immediately after the procedure. However, two patients had procedure-related complications, one with coil extrusion to the subarachnoid space without hemorrhage and one with thromboembolism subsequent to chemical thrombolysis. In the follow-up angiography, one major and five minor recurrences (for a total of six recurrences, 37.5%) were detected. However, the differences between the ACA aneurysm group and others were not statistically significant. Clinical outcomes were good for all of the patients at the time of discharge (mean mRS: 0.25, 0 to 1) and at the follow-ups (mean mRS: 0).

Conclusion: Despite a comparatively high recurrence rate, the endovascular treatment of distal anterior cerebral aneurysms is feasible and has a good clinical outcome.
