Does Diffusion Lesion Volume Above 70 mL Preclude Favorable Outcome Despite Post-Thrombolysis Recanalization? Clinical Sciences
Conclusions— Patients with DWI lesion volume ≥70 mL can benefit from recanalization after intravenous recombinant tissue-type plasminogen activator. This may partly reflect a larger amount of DWI lesion reversal.

Risk Reduction of Cerebral Stroke After Stereotactic Radiosurgery for Small Unruptured Brain Arteriovenous Malformations Clinical Sciences
Conclusions— SRS can significantly reduce the risk of stroke in the patients with small unruptured arteriovenous malformations. To definitively determine the clinical benefits of SRS, a longer follow-up will be necessary. However, based on our results, we can recommend SRS for patients who face a latent risk for stroke from this intractable vascular disease.

Magnetic Resonance Imaging of Plaque Morphology, Burden, and Distribution in Patients With Symptomatic Middle Cerebral Artery Stenosis Clinical Sciences
Conclusions— Our results lead to a 2-fold conclusion: (1) The classification system of both thickening pattern and distribution of the lesion can be simplified by using distribution pattern only and (2) differentiation between symptomatic and asymptomatic atherosclerotic lesions was possible using intracranial vessel wall imaging.

Computed Tomography Perfusion-Based Decision Making for Acute Ischemic Stroke —Missing the Mismatch
We present a case of an 80-year-old man admitted because of acute ischemic stroke. CT angiography demonstrated left proximal M2 occlusion. As CTP demonstrated signs of large ischemic core with no significant penumbra, mechanical thrombectomy was not performed following tPA administration.

Impact of Thrombus Length on Outcomes After Intra-Arterial Aspiration Thrombectomy in the THERAPY Trial Clinical Sciences
Conclusions—Ischemic stroke patients with longer symptomatic thrombi have worse 90-day clinical outcomes but may have a greater relative benefit of aspiration thrombectomy over IV r-tPA alone.Clinical Trial Registration—URL: http://www.clinicaltrials.gov. Unique identifier: NCT01429350.

Predictive Value of Computed Tomography Angiography-Determined Occlusion Type in Stent Retriever Thrombectomy Clinical Sciences
Conclusions—CTA-determined branching-site occlusion was significantly associated with SR success. Furthermore, among the 3 rapidly- and readily-assessable pre-procedural findings, CTA-determined branching-site occlusion had the greatest predictive power for SR success.

Pseudo-Occlusion of the Internal Carotid Artery Predicts Poor Outcome After Reperfusion Therapy Clinical Sciences
This study aimed to evaluate the occurrence rate of the internal carotid artery pseudo-occlusion (ICA-PO) on 4-dimensional–computed tomography angiography and to investigate its relationship with clinical outcome after reperfusion therapy.Methods—In this case–control study, we retrospectively reviewed our prospectively collected database for consecutive acute ischemic stroke patients who received reperfusion therapy between June 2009 and February 2017. ICA-PO was defined when the arterial segment was not opacified on peak arterial phase yet was subsequently patent after artery peak phase on 4-dimensional–computed t...

Thrombectomy for M1-Middle Cerebral Artery Occlusion Brief Report
Conclusions—The angiographic phenotype of the occlusion site may be associated with a different response to SR and CA in this preliminary experience.

Similar Outcomes for Contact Aspiration and Stent Retriever Use According to the Admission Clot Burden Score in ASTER Clinical Sciences
Conclusions—First-line mechanical thrombectomy with contact aspiration compared with stent retriever did not result in an increased successful reperfusion rate in acute ischemic stroke patients with large vessel occlusion of the anterior circulation according to the admission CBS. The latter, however, seems to be a reliable prognostic indicator of angiographic and clinical outcome.

Contrast-Induced Nephropathy in Ischemic Stroke Patients Undergoing Computed Tomography Angiography: CINISter Study
Goal: Computed tomography angiography (CTA) is a well-tolerated, noninvasive study of the intracranial vascular circulation; however, contrast-induced nephropathy (CIN) has been reported in 5%-7% of patients undergoing CTA. Limited studies have evaluated the risks of CIN in patients undergoing CTA. Our study was designed to evaluate the prevalence and risk factors for CIN in patients with ischemic stroke who receive a CTA. Materials and Methods: Single-center, nested, case-control study of patients with ischemic stroke who received a CTA between June 18, 2012 and January 1, 2016.

Computational Fluid Dynamics Analysis of Lateral Striate Arteries in Acute Ischemic Stroke Using 7T High-resolution Magnetic Resonance Angiography
Background: Infarcts in the lateral striate artery (LSA) territory can be caused by several pathological changes, including lipohyalinosis and microatheroma. However, fluid dynamic effects on these changes remain unknown. Thus, we investigated whether the fluid dynamic metrics of the LSAs were altered in patients with acute ischemic stroke using computational fluid dynamics (CFD) analysis. Methods: Fifty-one patients with acute ischemic stroke confined in the basal ganglia and/or corona radiata underwent high-resolution magnetic resonance angiography (HR-MRA) at 7T.

The Value of Whole-Brain Perfusion Parameters Combined with Multiphase Computed Tomography Angiography in Predicting Hemorrhagic Transformation in Ischemic Stroke
Objective: To explore the value of whole-brain perfusion parameters combined with multiphase computed tomography angiography (MP-CTA) in predicting the hemorrhagic transformation (HT) of ischemic stroke. Methods: A total of 64 patients with ischemic stroke who underwent noncontrast computed tomography, computed tomography perfusion imaging, and computed tomography angiography before treatment from August 2017 to June 2019 were included retrospectively. The perfusion parameters cerebral blood volume (CBV), cerebral blood flow (CBF), time to peak (TTP), mean transit time (MTT), time to maximum (Tmax), and permeability surfac...
