A, 3D view of a complex right MCA aneurysm involving both superior and inferior trunks. B, Right internal carotid artery oblique angiogram demonstrating the complex right MCA aneurysm. C, Postembolization oblique DSA view after both superior and inferior trunks were stented in Y-configuration with suboptimal aneurysm packing. D, One-year control angiography in anterior-posterior view revealing the reconstruction of MCA bifurcation and complete occlusion of the aneurysm.

A, 3D view of a complex left MCA aneurysm with both superior and inferior trunks of MCA originating from the aneurysm sac. B, Preoperative DSA revealing both trunks of left MCA stented in Y-configuration, creating a neck. C, Six-month control DSA showing stable aneurysm occlusion. D and E, Two-year control angiography with subtracted (D) and nonsubtracted (E) views confirming long-term aneurysm occlusion and MCA bifurcation reconstruction.
