Arterial Reocclusion And Distal Embolization During Endovascular Treatment Using New Generation Stent Retrievers In Acute Ischemic Stroke Patients (P4.299)
CONCLUSIONS: Arterial reocclusion and distal embolization occur in 16[percnt]-18[percnt] of acute ischemic stroke patients undergoing mechanical thrombectomy with new stent retrievers. The rates are no higher than those observed in cohorts treated without stent retrievers.Disclosure: Dr. Herial has nothing to disclose. Dr. Qureshi has nothing to disclose.

Multi‐modal CT in acute stroke: wait for a serum creatinine before giving intravenous contrast? No!
ConclusionsThe incidence of CIN is low when MMCT is used routinely to assess acute stroke patients. In this population, CIN was a biochemical phenomenon that did not have clinical manifestations, cause chronic kidney disease, require dialysis, or negatively impact on 90‐day mRS outcomes. Renal profiling and waiting for a baseline serum‐creatinine are an unnecessary delay to emergency reperfusion treatment.

Prediction of Blood-Brain Barrier Disruption and Intracerebral Hemorrhagic Infarction Using Arterial Spin-Labeling Magnetic Resonance Imaging Clinical Sciences
Background and Purpose—Arterial spin-labeling magnetic resonance imaging is sensitive for detecting hyperemic lesions (HLs) in patients with acute ischemic stroke. We evaluated whether HLs could predict blood–brain barrier (BBB) disruption and hemorrhagic transformation (HT) in acute ischemic stroke patients.Methods—In a retrospective study, arterial spin-labeling was performed within 6 hours of symptom onset before revascularization treatment in 25 patients with anterior circulation large vessel occlusion on baseline magnetic resonance angiography. All patients underwent angiographic procedures intended for endovasc...

Diversity of Stroke Presentation in CADASIL: Study from Patients Harboring the Predominant NOTCH3 Mutation R544C
This study investigated the clinical stroke presentation and cranial magnetic resonance imaging (MRI) findings in a group of patients with CADASIL. We reviewed the clinical stroke presentation and brain MRI findings in 73 consecutive Korean patients aged>18 years diagnosed with CADASIL between May 2004 and April 2009. Brain MRI images were also scored for lacunar infarction and cerebral microbleeds. Intracranial atherosclerosis (ICAS) was assessed by magnetic resonance angiography. Disability was measured with the modified Rankin scale (mRS) and classified as good (mRS score 0-2) or poor (mRS score 3-5). In this study, 65 ...

Impact of Collaterals on Successful Revascularization in Solitaire FR With the Intention for Thrombectomy Clinical Sciences
Conclusions— Better collaterals were associated with lower glucose, lower blood pressure, smaller baseline infarcts in SWIFT, and greater likelihood of successful revascularization without hemorrhage and good clinical outcomes. Clinical Trial Registration— URL: http://www.clinicaltrials.gov. Unique identifier: NCT01054560.

Outcomes of manual aspiration thrombectomy for acute ischemic stroke refractory to stent-based thrombectomy
Conclusions This study suggests that MAT with the Penumbra reperfusion catheter can further increase the revascularization rate without serious complications in patients with acute stroke with refractory occlusions after SBT with a Solitaire stent.

Systemic thrombolysis in acute ischemic stroke patients with unruptured intracranial aneurysms
Conclusions: Our prospectively collected multicenter data, coupled with the findings of the meta-analysis, indicate the potential safety of IVT in AIS patients with UIA.

Collateral flow as causative of good outcomes in endovascular stroke therapy
Conclusions Improved collateral flow in patients with AIS undergoing endovascular therapy was associated with improved radiographic and clinical outcomes. Independent of age, vessel occlusion and time, in patients with comparable ischemic burdens, changes in collateral grade alone led to significant differences in initial stroke severity as well as ultimate clinical outcome.

Safety of Endovascular Thrombectomy in Patients Receiving Non-Vitamin K Antagonist Oral Anticoagulants Brief Reports
Conclusions— Thrombectomy in non–vitamin K antagonist oral anticoagulant patients seems safe although a comparatively high rate of asymptomatic hemorrhagic transformation was noted. Confirmation in larger prospective controlled cohorts is necessary. Clinical Trial Registration— URL: http://www.clinicaltrials.gov. Unique identifier: NCT01850797.

Interaction of Recanalization, Intracerebral Hemorrhage, and Cerebral Edema After Intravenous Thrombolysis Clinical Sciences
Conclusions— Large ischemic core was associated with poorer outcomes and both early vasogenic brain edema and ICH, but recanalization on 24-hour CT angiography was associated with clinically favorable outcome. There was no significant interaction of recanalization and large core volume for any outcomes. The association of hemorrhage or brain edema with post-thrombolysis reperfusion is unclear.

Is Unexplained Early Neurological Deterioration After Intravenous Thrombolysis Associated With Thrombus Extension? Clinical Sciences
Conclusions—In this study, unexplained END occurring after thrombolysis was independently associated with susceptibility vessel sign extension, suggesting in situ thrombus extension or re-embolization. These findings strengthen the need to further investigate early post-thrombolysis administration of antithrombotics to reduce the risk of this ominous clinical event.

Primary Angiitis of the Central Nervous System Clinical Sciences
Conclusions—Adult primary angiitis of the central nervous system is a heterogenous disease, with multiterritorial, distal, and bilateral acute stroke being the most common pattern of parenchymal lesions found on magnetic resonance imaging. Our findings suggest a higher than previously thought prevalence of hemorrhagic transformation and other hemorrhagic manifestations.

Endovascular thrombectomy beyond 24 hours from ischemic stroke onset: a propensity score matched cohort study
Conclusion In this real world study, EVT beyond 24 hours from stroke onset or last known well appeared to be feasible, with comparable safety and functional outcomes to EVT initiation between 6 and 24 hours. Randomized trials assessing the efficacy of EVT in the VL window are warranted, but may only be feasible with a large international collaborative approach.
