Background: For patients with acute ischemic stroke (AIS), the thrombus density on non-enhanced CT (NECT) indicates composition of thrombus, a characteristic that impacts efficacy mechanical thrombectomy (MT). A previous meta-analysis suggested correlation between higher and successful reperfusion, but some new studies have drawn different conclusions. This single-center study aimed to detect association reperfusion outcomes based various strategies. Methods: We reviewed AIS who underwent MT...
Objective: Although the benefits of good collateral circulation on infarct volume and outcomes have been confirmed in previous studies, few studies investigated relationship between hemorrhagic transformation (HT) acute ischemic stroke (AIS). This study aimed to assess whether is an essential factor HT after endovascular treatments (EVTs). Methods: In total, 71 consecutive AIS patients who underwent EVTs July 2015 February 2019 were retrospectively studied. The correlations among HT, vessels...
The aim of this study was to verify the value collateral circulation and B-type natriuretic peptide (BNP) in predicting clinical outcomes patients with acute ischemic stroke (AIS) their biomarker for subtypes before endovascular treatment (EVT).In retrospective study, 182 who underwent EVT unilateral anterior large-vessel occlusion between March 2016 January 2022 were analyzed. modified scoring system on four-dimensional computed tomography angiography (4D CTA-CS) used assess status,...
Abstract Objectives To evaluate the application of black-blood CT (BBCT) in carotid artery wall imaging and its accuracy disclosing stenosis rate plaque burden artery. Methods A total 110 patients underwent contrast-enhanced scan with two phases, BBCT images were obtained using contrast-enhancement (CE)-boost technology. Two radiologists independently scored subjective image quality on computerized tomography a 4-point scale then further analyzed types. The was measured compared CTA. that...
Purpose: This study aimed to identify independent predictors for the risk of hemorrhagic transformation (HT) in arterial ischemic stroke (AIS) patients. Methods: Consecutive patients with AIS due large artery occlusion anterior circulation treated mechanical thrombectomy (MT) were enrolled a tertiary center. Demographic and medical history data, admission lab results, Circle Willis (CoW) variations collected from all Results: Altogether, 90 included this study; among them, 34 (37.8%) had HT...
Objectives: To develop an efficient and quantitative assessment of collateral circulation on time maximum intensity projection CT angiography (tMIP CTA) in patients with acute ischemic stroke (AIS). Methods: Eighty-one AIS who underwent one-stop CTA-CT perfusion (CTP) from February 2016 to October 2020 were retrospectively reviewed. Single-phase CTA (sCTA) tMIP developed CTP data. Ischemic core (IC) volume, penumbra mismatch ratio calculated. The Tan scale was used for the qualitative...
This study compared ischemic core and penumbra volumes obtained using different computed tomography perfusion (CTP) software evaluated the predictive value of CTP magnetic resonance imaging (MRI) results for 90-day outcomes.In total, 105 acute stroke patients who underwent endovascular treatment from January 2016 to December 2020 were included. Patients divided into good poor outcome groups by a modified Rankin Scale score. Computed OleaSphere Vitrea assess volumetric relationship with MRI...
To establish a novel cortical venous collateral score based on four-dimensional computed tomography angiography (4D CTA) and to assess the relationship between clinical outcomes in patients with acute ischemic stroke (AIS) after endovascular treatments (EVTs).This was retrospective case-control study designed evaluate all consecutive large vessel occlusion unilateral anterior circulation who underwent EVTs at single institution. Two independent neuroradiologists evaluated collaterals using...
The aim of the study was to find potential roles B-type natriuretic peptide (BNP) and imaging markers on distinguishing cardioembolic (CE) stroke from non-CE stroke, so as provide useful information for making individualized endovascular treatment (EVT) plan patients with acute ischemic (AIS).The unilateral anterior circulation large vessel occlusion who underwent EVT between March 2016 December 2021 were analyzed in this study, retrospectively. risk factors, laboratory test indicators,...
Objective: To explore the significance of multi-parameter semiquantitative Alberta Stroke Program Early CT Score (ASPECTS) in detecting core infarction acute ischemic stroke (AIS) patients. Methods: Twenty-one consecutive AIS patients from Beijing Hospital were retrospectively reviewed this study August 2016 to 2017. All presented within 6 hours since symptom onset.All underwent one-stop dynamic whole brain 4D CTA-CTP scan before treatments (intravenous thrombolysis, mechanical thrombectomy,...
