Stent placement for the treatment of nonsaccular aneurysms of the vertebrobasilar system

Full access

Vertebrobasilar nonsaccular aneurysms represent a small subset of intracranial aneurysms and usually are among the most challenging to be treated. The aim of this article was to review the literature and summarize the experience in the treatment of these lesions with endovascular approaches. The method of stent implantation as it is performed at the authors' institution, including options available for vertebral artery access, is described. Practitioners involved in the treatment of these lesions should be aware of the potential application of intravascular stent placement as well as the associated postprocedure risks and potential complications.

Abbreviations used in this paper:CT = computerized tomography; MR = magnetic resonance; SAH = subarachnoid hemorrhage; VA = vertebral artery.
