HyperForm balloon-assisted endovascular neck bypass technique to perform balloon or stent-assisted treatment of cerebral aneurysms

S H Cekirge et al. AJNR Am J Neuroradiol. 2007 Aug.

Abstract

We describe a technique to bypass aneurysm neck using the HyperForm balloon to perform balloon- or stent-assisted endovascular treatment of complex large or giant aneurysms with very wide neck in which other methods would fail to obtain an access distal to the aneurysm.
