Curative Reconstruction of Giant Fusiform Intracranial Aneurysms with Flow-Diverter and Self-expanding Stents.
OBJECTIVE
To demonstrate the curative reconstruction of two giant fusiform aneurysms using a combination of flow-diverter stents and self-expanding stents for intracranial use.


METHODS
Two cases that would have been difficult to manage with standard methods: one patient with deficiencies of cranial nerves VI and VII on the left, acute diplopia, and an aneurysm of the vertebrobasilar bifurcation, the other with diplopia, deficiencies of cranial nerves III and VI, and an aneurysm of the intracavernous internal carotid artery. INTERVENTION OR TECHNIQUE: Complete reconstruction was achieved using a combination of flow-diverter and self-expandable stents. Follow-up investigations at 6 months demonstrated the complete reconstruction of the arteries and angiographically determined disappearance of the aneurysms with resolution of the clinical profile. The patients' outcome was excellent (modified Rankin Scale: 0).


CONCLUSIONS
This technique enables safe and definitive treatment of lesions that would be difficult to manage with other methods. The greater metal surface does not seem to interfere with the perforating arteries originating from the segments involved.
