Flow diverters are an exciting new class of endovascular devices that treat aneurysms by curative reconstruction of the parent artery. The Pipeline embolization device (PED) is the first FDA-approved intracranial flow diverting device available in the USA. This paper presents periprocedural results with the device in a series of 35 consecutive cases. ⋯ Treatment of cerebral aneurysms with the PED carries an acceptable risk profile when a rigorous and uniform technique is used. Although the long-term results will need to be analyzed, the immediate procedural outcomes in the study series using this technique appear quite promising.

The shorter the time interval between the estimation of the ischemic core by imaging and reperfusion, the more likely that core expansion is minimized. We aimed to assess the feasibility of achieving an ultrashort imaging to reperfusion time in routine clinical practice. ⋯ An imaging to endovascular reperfusion time of <60 min is feasible and resulted in minimal core expansion on follow-up imaging in patients with acute ischemic stroke.

Greater attention has been directed to endovascular recanalization of acute ischemic stroke in septuagenarians and above. ⋯ Multimodal endovascular recanalization of acute ischemic stroke is a relatively safe treatment option in patients older than 75 years of age. Careful patient selection by clinical and radiographic inclusion criteria is necessary for the successful management of stroke in this age group.

Multicenter Study
Advanced modality imaging evaluation in acute ischemic stroke may lead to delayed endovascular reperfusion therapy without improvement in clinical outcomes.
Advanced neuroimaging techniques may improve patient selection for endovascular stroke treatment but may also delay time to reperfusion. We studied the effect of advanced modality imaging with CT perfusion (CTP) or MRI compared with non-contrast CT (NCT) in a multicenter cohort. ⋯ The current retrospective study shows that multimodal imaging may be associated with delays in treatment without reducing hemorrhage rates or improving clinical outcomes. This exploratory analysis suggests that prospective randomised studies are warranted to support the hypothesis that advanced modality imaging is superior to NCT in improving clinical outcomes.
