Retractable self-expandable stent for endovascular treatment of wide-necked intracranial aneurysms: preliminary experience.
Intracranial stenting combined with endosaccular coiling is a therapeutic alternative for the endovascular treatment (EVT) of wide-necked intracranial aneurysms. The current limitation of available stents is the impossibility to reposition them once they are partially deployed. Recently, the first retractable self-expandable stent has been developed and we sought to evaluate the use of this stent for EVT of wide-necked intracranial aneurysms. ⋯ The Leo stent appears very useful for EVT of wide-necked intracranial aneurysms. The advantage of this stent is the possibility to reposition it which allows a very precise positioning across the aneurysm neck.

Neurocognitive dysfunction has been shown to occur in roughly 25% of patients undergoing carotid endarterectomy (CEA). Despite this, little is known about the mechanism of this injury. Recently, several groups have shown that new diffusion weighted imaging (DWI)-positive lesions are seen in 20% of patients undergoing CEA. We investigated to what degree neurocognitive dysfunction was associated with new DWI lesions. ⋯ Neurocognitive dysfunction after CEA does not seem to be associated with new DWI positive lesions.
