title: Endovascular treatment of ruptured aneurysms associated with fenestrated basilar artery. Two case reports.
abstract: Two patients with ruptured aneurysm associated with fenestrated basilar artery (BA) were treated using the endovascular approach. Angiography showed these patients had different types of BA bifurcation. One type had two points of bifurcation and a bridging artery in the BA fenestration, with the aneurysm at the bifurcation of the right loop of the fenestration. The aneurysm had different appearances on right and left vertebral angiograms. The other type had only one point of bifurcation, and the appearance of this aneurysm was similar on both angiograms. To ensure successful embolization, bilateral vertebral angiography should be performed for complete assessment of the morphological characteristics of aneurysm associated with fenestrated BA.
