Abstract
The aim of our study was to report a series of 15 consecutive patients with aneurysms of the proximal segment (A1) of the anterior cerebral artery. In 15 patients with diagnosed A1 aneurysms, representing 2.1% of 720 aneurysm patients treated at a University Clinical Center between October 1999 and August 2012, clinical presentation, neuroradiological findings, surgical treatment methods and outcome were retrospectively analyzed. Mean patient age was 53.06 (range 32 to 75) years. Ten saccular aneurysms were treated with micro neurosurgical approach via standard pterional craniotomy, four fusiform aneurysms with coiling, and one fusiform aneurysm with stent. No patients died during the operation. The mean follow-up period was 32 months (range 5 months to 7 years). Clinical outcomes revealed good recovery in all patients. Despite the general opinion that A1 aneurysms are benign lesions, an increasing number of reports have demonstrated their potential complications. To date, due to the rarity of A1 aneurysms, only a few consecutive series have been reported. Conduct of multicenter studies are required in order to understand clinical features of A1 aneurysms and devise a proper treatment plan.
Highlights
The course of the proximal segment (A ) of the anterior cerebral artery (ACA) varies greatly according to its length and dominance, sometimes looping under the frontal lobe [, ]
Handa et al, Yasargil et al, and Wakabayashi et al are among the few describing a series of patients with A aneurysms; most other reports have been studied of individual case [, ]
We present patients who were surgically treated for A segment aneurysms and describe clinical status, radiologic findings, treatment, and outcome
Summary
The course of the proximal segment (A ) of the anterior cerebral artery (ACA) varies greatly according to its length and dominance, sometimes looping under the frontal lobe [ , ]. A segment aneurysms constitute less than of all intracranial aneurysms, but they are challenging to treat because of their small size and close relationship to the perforating arteries [ , , ]. A segment aneurysms are smaller than other intracranial aneurysms [ - ]. The incidence of A aneurysms is low even in high-volume neurovascular centers, only a few cases every year are encountered. Handa et al, Yasargil et al, and Wakabayashi et al are among the few describing a series of patients with A aneurysms; most other reports have been studied of individual case [ , , , ]. The largest collection of A aneurysms published to date has been by Suzuki et al in with
