A 61-year-old man presented with a ruptured vertebral artery dissecting aneurysm manifesting as severe headache, which was treated by internal trapping, and later resulted in recanalization of the affected vertebral artery without aneurysm recurrence. Computed tomography revealed subarachnoid hemorrhage caused by a dissecting right vertebral artery aneurysm located just distal to the origin of the posterior inferior cerebellar artery. The patient underwent uneventful internal trapping. However, recanalization of the affected vertebral artery with stenosis was found on the 22nd postoperative day, apparently caused by insufficient thrombosis related to the short trapping length. No aneurysm recurrence or ischemic events were detected, so the patient was observed carefully. After 4 months, right vertebral angiography revealed that the vertebral artery was normal with no stenosis or aneurysm. Restoration of the vertebral artery without complication probably occurred by complete thrombosis of the aneurysm followed by reconstruction of the injured arterial wall. We adopted a conservative approach in this case, but additional embolization and/or stenting should be considered if high risk of rebleeding is suggested by angiographic findings, although the management of recanalization remains controversial.
