New angled fenestrated clips for fusiform vertebral artery aneurysms

New angled fenestrated clips are introduced for surgery of certain difficult aneurysms. Their usefulness was proven in two cases of fusiform vertebral artery aneurysms. The aneurysms were obliterated, new parent arteries were reconstructed, and the inclusion of adjacent vital nerves and vessels in the clips was avoided. Technical problems associated with the application of these clips are discussed.
