Objective:We report the first case of a vertebral artery (VA) dissecting aneurysm involving the posterior inferior cerebellar artery (PICA) treated by placing a stent on the PICA from the contralateral VA and parent artery occlusion in the acute hemorrhagic phase.

Case Presentation: The patient was a 47-year-old man with World Federation of Neurosurgical Societies (WFNS) grade 3 subarachnoid hemorrhage (SAH) and a VA dissecting aneurysm involving the origin of the PICA. We approached from the contralateral VA, and placed a stent from the PICA to VA to preserve the PICA, and parent artery occlusion of the VA was performed. As of 6 months postoperatively, no rebleeding or recurrence of aneurysm has been observed.

Conclusion: Although the use of stents in the acute phase is difficult, they can fully preserve the PICA and parent artery occlusion, and may be an effective treatment method to prevent rebleeding and chronic phase recurrence.
