Multicenter Study Observational Study
Safety and effectiveness of the Low Profile Visualized Intraluminal Support (LVIS and LVIS Jr) devices in the endovascular treatment of intracranial aneurysms: results of the TRAIL multicenter observational study.
To evaluate the safety and effectiveness of the low-profile braided intracranial stents called the Low Profile Visualized Intraluminal Support (LVIS) devices for stent-assisted coil embolization of wide-necked intracranial aneurysms. ⋯ The LVIS/LVIS Jr endovascular devices are safe and effective in the treatment of ruptured and unruptured intracranial aneurysms, with acceptable complication rates, very high immediate total occlusion rates, and stable angiographic results.

Case Reports Observational Study
LVIS Blue as a low porosity stent and coil adjuvant.
The LVIS Blue is an FDA-approved stent with 28% metallic coverage that is indicated for use in conjunction with coil embolization for the treatment of intracranial aneurysms. Given a porosity similar to approved flow diverters and higher than currently available intracranial stents, we sought to evaluate the effectiveness of this device for the treatment of intracranial aneurysms. ⋯ The LVIS Blue represents a safe option as a coil adjunct for endovascular embolization within both the proximal and distal anterior and posterior circulation.

Integration of data from clinical trials and advancements in technology predict a change in selection for treatment of patients with cerebral aneurysm. ⋯ The majority of unruptured aneurysms in the USA are now treated with endovascular coiling. Although surgical clipping is used for treatment of most ruptured aneurysms, its use is decreasing over time. Dissemination of endovascular procedures appears widespread across patient and hospital subgroups.

Extracranial internal carotid artery (ICA) occlusion can be overestimated on emergent single phase CT angiography (CTA) of stroke patients with isolated intracranial ICA occlusion. We aimed to measure the ability of identifying the extracranial site of presumed tandem ICA occlusions on pre-procedural CTA relative to catheter angiography during acute endovascular stroke therapy. ⋯ Emergency single phase CTA is highly sensitive but has reduced specificity to identify extracranial ICA occlusion in patients with intracranial ICA occlusion, which may confound planning for acute endovascular stroke therapy and cause over exclusion of patients with isolated ICA terminus occlusion from clinical trials.
