BackgroundPericallosal artery aneurysms at the bifurcation represent a special endovascular technical challenge given their distal location, commonly wide-neck morphology, small parent vessel diameter and potentially high recurrence rate after coiling given the bifurcation location. Y-configuration stent-assisted coil embolization techniques have been reported for the treatment of wide-neck aneurysms located at other vascular bifurcations and only rarely with A2 bifurcation aneurysms.MethodsA neurointerventional database was reviewed for identification of all cases of A2 bifurcation aneurysms that were treated with Y-stent configuration. The authors report clinical, technical and outcome data on four patients with pericallosal aneurysms who were treated with a Y-configuration stent-assisted coil embolization technique.ResultsA Y-configuration stent placement in the anterior cerebral artery/A2 bifurcation was successfully achieved in all four patients without significant technical difficulties. One patient presented with a previously ruptured and partially treated aneurysm and three patients with incidentally found aneurysms. All four patients had a Y-configuration stent placement in one setting. The Y-configuration allowed for complete occlusion of all four aneurysms with no recurrence or arterial occlusion on mean angiographic follow-up of 13.5 months (6-28).ConclusionTreating wide-neck pericallosal artery aneurysms at the bifurcation with Y-configuration stent placement is feasible and effective. This technique may be considered as a therapeutic option for wide-neck aneurysms that pose a difficult technical challenge.
