Stenting and coiling of a complex aneurysm of the posterior cerebral artery

1. 3D angiographic reconstruction of the complex aneurysm, a fusiform and partially thrombosed aneurysm that is not amenable to clipping. The image at right shows the flow vectors within the aneurysm.

2. A stent was placed in the vessel, and then coiling was performed through the stent. The patient tolerated the procedure well and was discharged from the hospital in good condition. If the attempt to place a stent had been unsuccessful, the neurosurgeons would have performed an operation to exclude the aneurysm from the circulation by trapping it and performing an arterial bypass around it
