Note:—Non indicates nondifferentiated by conventional angiography; RVA, right vertebral artery; LVA, left vertebral artery; BA; basilar artery; Lesion, dominant artery on the same side as the lesion; Supra, lesion was above PICA level; Infra, lesion was below PICA level; Non, nondifferentiated lesion by conventional angiography; Contra, dominant artery contralateral to the lesion; Both, codominant; GOS, Glasgow Outcome Score; PICA, posterior inferior cerebellar artery.
*
The patient had a left ruptured dissecting aneurysm and a right unruptured dissecting aneurysm, which were treated with trapping and a stent, respectively, .
