Silent Brain Infarction in Patients With Asymptomatic Carotid Artery Atherosclerotic Disease Brief Reports
Conclusions— Patients with asymptomatic ICA disease demonstrate a higher prevalence of SBI downstream from their ICA atherosclerotic disease compared with the contralateral side but only of the cortical and not lacunar SBI subtype.

Patient selection for stroke thrombectomy: Is CT head good enough?
Six randomized controlled trials have established the substantial benefit of mechanical thrombectomy for acute ischemic stroke patients presenting with large vessel occlusive disease.1–6 Enrolling patients with large clinical deficit in the setting of small completed infarct and rapid, complete, or near complete recanalization, and treatment with the most recent generation of thrombectomy devices, contributed to this success. Efforts to generalize the results of these trials beyond select, experienced centers have focused attention on workflow and developing consensus on patient selection. Optimizing outcomes require...

Vascular Tortuosity May Be Associated With Cervical Artery Dissection Clinical Sciences
Conclusions— CerAD is associated with tortuous cervical arteries, which may implicate weakened cervical vascular structure in these patients.

Cerebral angiography and intraarterial thrombolysis with streptokinase in acute ischemic stroke
【Background and Purpose】The purpose of this study was to evaluate the safety and efficacy of intra-arterial thrombolysis (IAT) using Streptokinase under cerebral angiography control (CAC) in patients with acute ischemic stroke due to middle cerebral artery (MCA) occlusion.

Absent Filling of Ipsilateral Superficial Middle Cerebral Vein Is Associated With Poor Outcome After Reperfusion Therapy Clinical Sciences
Conclusions—Lack of SMCV filling contributed to poor outcome after thrombolysis, especially when reperfusion was not achieved. The main deleterious effect of poor venous filling appears related to the development of brain edema.

Impact of hyperglycemia according to collateral status on reperfusion and outcomes in acute ischemic stroke after mechanical thrombectomy (S8.001)
Conclusions:The deleterious effect of hyperglycemia on functional outcome after endovascular thrombectomy is modified by collateral status at presentation. Higher glucose levels reduce likelihood of good outcome among patients with good collaterals, but do not affect outcome among patients with poor collaterals.Disclosure: Dr. Kim has nothing to disclose.

Vascular Anatomy Predicts the Risk of Cerebral Ischemia in Patients Randomized to Carotid Stenting Versus Endarterectomy Clinical Sciences
Background and Purpose—Complex vascular anatomy might increase the risk of procedural stroke during carotid artery stenting (CAS). Randomized controlled trial evidence that vascular anatomy should inform the choice between CAS and carotid endarterectomy (CEA) has been lacking.Methods—One-hundred eighty-four patients with symptomatic internal carotid artery stenosis who were randomly assigned to CAS or CEA in the ICSS (International Carotid Stenting Study) underwent magnetic resonance (n=126) or computed tomographic angiography (n=58) at baseline and brain magnetic resonance imaging before and after treatment. We invest...

Dose-Dependent Effect of Statin Pretreatment on Preventing the Periprocedural Complications of Carotid Artery Stenting Clinical Sciences
Background and Purpose—We investigated whether statin pretreatment can dose dependently reduce periprocedural complications in patients undergoing carotid artery stenting because of symptomatic carotid artery stenosis.Methods—We enrolled a consecutive series of 397 symptomatic carotid artery stenosis (≥50% stenosis on conventional angiography) treated with carotid artery stenting at 2 tertiary university hospitals over a decade. Definition of periprocedural complications included any stroke, myocardial infarction, and death within 1 month after or during the procedure. Statin pretreatment was divided into 3 categorie...

Tenecteplase in ischemic stroke offers improved recanalization: Analysis of 2 trials
Conclusions: Tenecteplase may offer greater recanalization efficacy compared to alteplase, possibly exaggerated in patients with complete vessel occlusions on baseline CTA.

Angiographic Microcirculatory Obstructions Distal to Occlusion Signify Poor Outcome after Endovascular Treatment for Acute Ischemic Stroke
In this study, we retrospectively evaluated presence of contrast stasis and absence of capillary blush on angiograms obtained by selective injections into the distal site of occlusive thrombi, prior to deployment of stentrievers, in patients undergoing endovascular treatment for acute MCA occlusion. The role of this novel angiographic strategy assessing distal antegrade flow in predicting procedural and clinical outcome was compared to previously defined, prognostic angiographic characteristics. A total of 7 (21%) out of 34 patients had contrast stasis and lack of capillary blush downstream to the injection site. None of t...

An Acute Ischemic Stroke Resulting from Aortic Dissection
A 39-year-old man with syncope and persistent dizziness was sent to stroke emergency. Patient's diffusion magnetic resonance imaging of brain showed acute ischemia in right cerebella and right occipital lobe, thus intravenous recombinant tissue plasminogen activator was given to him. However, the patient behaved rather restless with repeated complaint of back and thoracic pain. Further thorax computed tomography angiography confirmed that the underlying cause turned out to be aortic dissection.

Radiographic and Clinical Brain Infarcts in Cardiac and Diagnostic Procedures Clinical Sciences
Conclusions—One of 10 people with periprocedural RBIs during cardiac surgeries and invasive vascular diagnostic procedures resulted in strokes or transient ischemic attacks, which may serve as a potential surrogate marker of procedural proficiency and perhaps as a predictor of risk for periprocedural strokes.
