BACKGROUND: Pericallosal 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.
METHODS: A 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.
RESULTS: A 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).
CONCLUSION: Treating 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.
