Abstract
Flow reduction therapy is sometimes incorporated for difficult aneurysms, but it does not always work. A 42 year-old man was presented with headache, dizziness, and slight gait disturbance due to left thrombosed giant vertebral aneurysm. Clip ligation of the VA after the PICA origin was performed for flow reduction based on the CFD analysis. But as two months later, the aneurysm showed minor hemorrhage and hydrocephalus, thrombectomy and clip reconstruction of the VA was performed. He returned to the job with slight ipsi-lateral facial palsy (House & Brackmann grade 2).
