Occlusion process of right MCA bifurcation aneurysm. A and B, Preoperative 3D reconstruction and DSA images show the early bifurcating branch originating from the aneurysm sac. C and D, Six-month control angiogram and 3D image demonstrate the “remodeled artery.” E and F, Eighteen-month control angiogram and 3D image show the complete occlusion of the aneurysm with the bifurcating branch filling in reduced caliber.

Occlusion stages of left MCA bifurcation aneurysm. A, DSA image shows the aneurysm giving rise to superior trunk. B, Fluoroscopic image shows the deployment of the PED in the inferior trunk. C and D, Early and late phases of 6-month control angiogram demonstrate the reduced and delayed filling of the aneurysm sac with the significant stagnation. Bifurcating branch is also filling belated in reduced caliber. E and F, Early and late phases of 6-month control angiogram (lateral view) show reduced filling of the superior trunk with retrograde filling of the distal branches through pial collaterals. G, One-year control angiogram demonstrates the remodeled superior trunk. The superior trunk and its branches are still filling in reduced caliber. H, Eighteen-month control angiogram shows complete occlusion of the aneurysm, with the superior trunk coming to its original size. I, Thirty-month control angiogram shows the stable occlusion of the aneurysm with the patency of the bifurcating branch (note the carotid cave aneurysm in A, treated with PED as well).

Recanalized left MCA bifurcation aneurysm. A, Preoperative angiogram shows recanalization of the aneurysm previously treated by use of balloon-assisted coiling. Inferior trunk is emanating from the neck. B, Nonsubtracted image shows the PED placed within the superior trunk. C, Six-month control angiogram shows the remodeled inferior trunk (arrowhead). The “healing zone” appears as the “interruption” between the remodeled artery and bifurcation (arrow).
