This article provides our experience with a novel steerable microcatheter in such a situation, as well as a review of the literature. Case Description: A 73-year-old woman presented with right ptosis and external ophthalmoplegia. Magnetic resonance angiography revealed a giant right cavernous internal carotid artery aneurysm. Endovascular treatment was planned with flow diversion, but distal access was not possible using the standard technique. A 2.4-Fr steerable microcatheter, Leonis Mova Selective, was implemented, and by bending the catheter tip toward the distal parent artery, a guidewire could be guided distally. After the catheter exchange, two flow-diverting stents were deployed successfully. Conclusion: Steerable microcatheters may provide an option in treatment with flow-diverting stents for giant cerebral aneurysms where access to the distal parent artery is compromised.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/4d0ba9fb-6e89-49ba-bef8-9715423982e5/featured/hero-1781559768186.png","publishDate":"2024-02-09T00:00:00.000Z","doi":"10.25259/SNI_974_2023","categories":["Neurovascular","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/api/articles/4d0ba9fb-6e89-49ba-bef8-9715423982e5/pdf"}
