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...

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...

Intracranial Vessel Wall MRI in Cryptogenic Stroke and Intracranial Vasculitis
Introduction: Intracranial vasculopathies easily elude classic stroke work-up. We aim in this work to show that vessel wall-MRI could prove an efficient alternative to digital subtraction angiography for the diagnosis of intracranial vasculopathies by identifying intracranial arterial vessel walls anomalies and contrast enhancement, suggestive of angiitis of the central nervous system. Materials and methods: Clinical and imaging characteristics of stroke patients diagnosed with primary angiitis of the central nervous system based on vessel wall-MRI were retrospectively reviewed and the clinical and imaging features of angi...

Interactive effect of susceptibility-diffusion mismatch and recanalization status on clinical outcome in large vessel occlusion stroke
Objective: To investigate the interactive effect of susceptibility-diffusion mismatch and recanalization status on clinical outcome in patients with acute ischemic stroke due to large vessel occlusion.Methods: In this prospective study, consecutive ischemic stroke patients admitted within 24 h from symptom onset underwent emergency multimodal MRI at admission, including diffusion-weighted imaging (DWI), susceptibility-weighted imaging (SWI), and time-of-flight magnetic resonance angiography (TOF-MRA).

The clinical value of head-neck joint high-resolution vessel wall imaging in ischemic stroke
Imaging of intracranial vasculature is an important aspect of the workup for patients with stroke, transient ischemic attack (TIA), or suspected cerebrovascular disease1. In clinical setting, brain magnetic resonance imaging (MRI) plus intracranial three-dimensional time-of-flight magnetic resonance angiography (3D TOF MRA) is one of the most widely used imaging packages for patients who were suspected of ischemic stroke. Recently, high resolution intracranial vessel wall imaging (IVWI) , which is capable of exhibiting intracranial lesions directly including identifying the etiologies of intracranial stenosis, evaluating p...

Asymmetry of medullary veins on multiphase CT-angiography in patients with acute ischemic stroke
The management of acute ischemic stroke (AIS) has rapidly evolved over the last decade with the advancement in neuroimaging selection methods and endovascular treatment techniques. CT perfusion (CTP) with automated post-processing is the most widely used technique for extended-time window selection of patients for intra-arterial interventions based on recent clinical trials.1,2 CTP provides predictive information about stroke outcome, however the predictive ability remains moderate with area under the curve (AUC) approximately 0.6.

Bilateral large vessel occlusion causing massive ischemic stroke in a covid-19 patient
The case of a 70-year-old male presenting an ischemic stroke related to COVID-19 infection is described. He was initially admitted to the hospital with respiratory insufficiency syndrome secondary to pneumonia caused by SARS Co2. In the next days, he developed rapid neurological deterioration characterized by drowsiness which progressed to deep coma. D-dimer was elevated. Brain CT scan showed bilateral massive ischemic stroke located in the anterior circulation, CT angiogram showed occlusion in the left internal carotid artery and the right middle cerebral artery.
