title: Flow diverter placement for management of dissecting ruptured aneurysm in a non-fused basilar artery.
abstract: Intracranial vertebral artery dissection can be associated with subarachnoid hemorrhage (SAH) and pseudoaneurysm formation. Dissecting aneurysms have a high risk of rebleeding in the acute phase. To our knowledge, the management of an acute vertebrobasilar junction dissecting aneurysm associated with a basilar non-fusion has not been previously reported. We report here a case of SAH due to rupture of a dissecting aneurysm involving the vertebrobasilar junction and extending to involve the right limb and proximal junction of a non-fused basilar artery, managed by insertion of a flow-diverting stent with excellent clinical outcome and long-term patency of the flow diverter.
