Background: Dissecting intracranial pseudoaneurysms represent a challenge for treatment both endovascularly and surgically.
Methods: We review the treatment course of a ruptured anterior inferior cerebellar artery (AICA) dissecting pseudoaneurysm in a 50-year-old patient and review the history of dissecting aneurysms and AICA aneurysms treatment.
Results: An aneurysm cure was achieved using flow diversion in the AICA. The recent introduction of flow diversion devices that can be deployed through 0.017" microcatheters represents a new avenue for treatment of aneurysms.
Conclusion: To the best of our knowledge this is the first published case of flow diversion in the(?) AICA to treat a dissecting aneurysm. The introduction of Silk Vista Baby and similar future devices is likely to widen the scope of aneurysm treatment utilizing flow diversion in distal distribution with small parent arteries.
