Magnetic Resonance Imaging of Acute Stroke
Neuroimaging plays a critical role in the management of patients with acute stroke syndrome, with diagnostic, therapeutic, and prognostic implications. A multiparametric magnetic resonance (MR) imaging protocol in the emergency setting can address both primary goals of neuroimaging (ie, detection of infarction and exclusion of hemorrhage) and secondary goals of neuroimaging (ie, identifying the site of arterial occlusion, tissue characterization for defining infarct core and penumbra, and determining stroke cause/mechanism). MR imaging provides accurate diagnosis of acute ischemic stroke (AIS) and can differentiate AIS fro...

First-line lesional aspiration in acute stroke thrombectomy using a novel intermediate catheter: Initial experiences with the SOFIA.
CONCLUSIONS: Lesional aspiration with SOFIA is in line with published data. The SOFIA may be used as a first-line device, aiming at fast recanalization by sole aspiration with good safety and efficacy. If unsuccessful, it converts into part of a stent retriever-based multimodality treatment. PMID: 26908589 [PubMed - as supplied by publisher]

Endovascular Treatment versus Best Medical Treatment in Patients with Acute Ischemic Stroke: A Meta-Analysis of Randomized Controlled Trials ADULT BRAIN
CONCLUSIONS: Compared with best medical treatment, the odds of achieving a favorable outcome or excellent outcome at 3 months postrandomization are approximately 80% higher with endovascular treatment among patients with acute ischemic stroke.

Stent-Retriever Thrombectomy for Acute Anterior Ischemic Stroke with Tandem Occlusion: A Systematic Review and Meta-Analysis
ConclusionSRT with emergency carotid stenting is associated with acceptable safety and efficacy in acute anterior stroke patients with tandem occlusion compared to natural history. However, the best modality to treat proximal stenosis is based on an individual case basis.Key Points•Stent retriever thrombectomy of tandem occlusion is efficient and safe.• Emergent carotid stenting during thrombectomy increase symptomatic intracranial haemorrhage without impact mortality.•Thrombectomy of tandem anterior circulation occlusion may be the first therapeutic option

Can a 15-sec FLAIR replace conventional FLAIR sequence in stroke MR protocols?
Conclusion EPI-FLAIR allows a drastic reduction of acquisition time devoted to FLAIR sequence and minimizes motion artifacts. Compared with cFLAIR, it is however associated with increased risk of undiagnosed stroke mimics and lower PPV for identifying<4.5-hrs infarctions.

Postprocedure Subarachnoid Hemorrhage after Endovascular Treatment for Acute Ischemic Stroke
CONCLUSIONSThe rates of independent functional outcome were lower among subjects with postprocedure type 2 SAHs but not in subjects with type 1 SAH.

Improving the detection sensitivity of pH ‐weighted amide proton transfer MRI in acute stroke patients using extrapolated semisolid magnetization transfer reference signals
ConclusionsThe quantitative APT study using the extrapolated semisolid magnetization transfer reference signal approach enhances APT MRI sensitivity to pH compared with conventional APT‐weighted MRI, allowing more reliable delineation of an ischemic acidosis in the penumbra.

Impact of Anesthesia on the Outcome of Acute Ischemic Stroke after Endovascular Treatment with the Solitaire Stent Retriever INTERVENTIONAL
CONCLUSIONS: In this single-center study, the anesthetic management during stent retriever thrombectomy with general anesthesia or conscious sedation had no impact on the outcome of patients with large-vessel occlusion in the anterior circulation.

Hyper-attenuating brain lesions on CT after ischemic stroke and thrombectomy are associated with final brain infarction.
Conclusions Hyper-attenuating lesions on head NCCT scans performed after endovascular treatment of AIS may predict final brain infarcted areas. The prediction appears to be higher in the deep brain regions compared with the cortical regions. PMID: 28950737 [PubMed - as supplied by publisher]

Endovascular management of extracranial occlusions at the hyperacute phase of stroke with tandem occlusions
Conclusions ervical occlusion with coils and thrombectomy with stent-retrievers may be relevant to prevent early embolic recurrence in cervical occlusions with intraluminal thrombus. Stent-retrievers should be further assessed as a first-line approach, since delayed stroke may occur following occlusion with coils.

Safety profile of an 8F femoral arteriotomy closure using the Angio-Seal device in thrombolysed acute stroke patients undergoing thrombectomy.
Conclusion Use of the Angio-Seal closure device for 8F femoral access is safe in acute stroke patients. Intravenous thrombolysis prior to endovascular thrombectomy does not significantly alter femoral access site complication rate if this approach is used.

Endovascular management of extracranial occlusions at the hyperacute phase of stroke with tandem occlusions
ConclusionsCervical occlusion with coils and thrombectomy with stent-retrievers may be relevant to prevent early embolic recurrence in cervical occlusions with intraluminal thrombus. Stent-retrievers should be further assessed as a first-line approach, since delayed stroke may occur following occlusion with coils. Medical treatment alone may be sufficient when no cervical intraluminal thrombus is present, the Willis polygon is effective, and the cervical occlusion can be crossed easily to perform the intracranial thrombectomy.
