Abstract

Aneurysms at the vertebrobasilar junction are often found with basilar artery (BA) fenestration We encountered 10 consecutive cases of aneurysms associated with BA fenestration The purpose of this study is to describe the frequency, clinical features, and outcome of these aneurysms treated by endovascular procedure The incidence of these aneurysms in our series was 1.9% All aneurysms were successfully treated by coil embolization. Half of them were treated by using simple technique, and the other half were treated by using adjunctive techniques such as balloon remodeling technique. 70% of these cases were ruptured, and all except one case showed good recovery at the time of discharge We found 63 reported cases of this aneurysm in the literature between 2000 and 2012 57 out of 63 aneurysms were treated by endovascular means with good clinical results The usefulness of endovascular procedure is reported to be superior to surgical clipping because of their anatomical complexity and the difficulty of surgical exposure for clipping We conclude that outcome of these aneurysms is favorable and endovascular procedure has become their standard treatment for these aneurysms.
