Y-stent-assisted coil embolization of anterior circulation aneurysms using two Solitaire AB devices: a single center experience.
Wide-neck intracranial aneurysms remain a challenge to endovascular treatment. We describe our experience in repairing wide-neck aneurysms of the anterior circulation located at arterial branch points using coil embolization assisted by Y-stenting using two Solitaire(®) stents.Six wide-neck intracranial aneurysms located on the middle cerebral artery bifurcation( 3), pericallosal artery( 1), and anterior communicating artery( 2) were repaired by Y-stent-assisted coil embolization using two Solitaire(®) stents. Four cases were incidental findings of aneurysm and two cases were previously treated ruptured aneurysms that had undergone recanalization. All the cases were successfully treated without complications. Follow-up by digital subtraction angiography and magnetic resonance angiography at six months showed the stents to be patent with no recanalization of the aneurysm sacs. Repairing wide-neck aneurysms of the anterior circulation by Y-stent-assisted coil embolization using two Solitaire(®) stents is a simple and safe method of treating complex aneurysms. While the results are promising, larger series with longer term follow-ups are needed to corroborate that this treatment method is superior to other techniques.
