Objective : Intracranial vertebral artery dissecting aneurysms are rare lesions that are considered an important cause of spontaneous subarachnoid hemorrhage. We report our decade-long experience in treating ruptured intracranial vertebral artery dissecting aneurysms. Materials and Methods : This retrospective single-center study included 21 consecutive patients between February 2005 and March 2015. Their clinical features included radiologic finding at the initial examination, treatment modality, functional outcome at the last follow-up, mortality, and radiologic outcome at more than 6 months after the initial treatment. Results : All 16 aneurysms were treated endovascularly; aneurysm trapping was performed in 9 patients and vascular reconstruction was performed in 7 patients. For 6 aneurysms involving the posterior inferior cerebellar artery (PICA), the modalities of treatment were aneurysm trapping in 3 patients and vascular reconstruction in 3 patients. The mean duration of follow-up was 29 months (range, 6-70 months). Five patients expired, indicating a mortality rate of 31%. In surviving patients, the unfavorable outcome rate (modified Rankin Scale [mRS] > 2) was 36%. The overall mean mRS for survivors was 1.8. Angiographic follow-up in 11 survivors at 13 months, (range, 6-46 months) revealed recanalization of the aneurysm in one patient. Conclusions : Ruptured intracranial vertebral artery dissecting aneurysm is associated with poor functional outcome and high mortality. More immediate treatments are needed due to the high rebleeding rate in this disease condition. Endovascular treatment may be a useful option for ruptured intracranial vertebral artery dissecting aneurysms.
