Utility of Duranta, a wireless patch-type electrocardiographic monitoring system developed in Japan, in detecting covert atrial fibrillation in patients with cryptogenic stroke: A case report
Rationale: Subcutaneous implantable electrocardiographs are highly effective in detecting covert atrial fibrillation (AF) in cryptogenic stroke. However, these invasive devices are not indicated for all cryptogenic stroke patients, and noninvasive improvements over conventional Holter-type ambulatory electrocardiography are needed. We evaluated the clinical application and effectiveness of Duranta (ImageONE Co., Ltd.), a wireless patch-type electrocardiographic monitoring system developed in Japan for chronically ill patients or home-based patients at the end of life. A Duranta device was used to detect covert AF in patien...

Systematic review with network meta-analysis: Diagnostic values of ultrasonography, computed tomography, and magnetic resonance imaging in patients with ischemic stroke
Conclusion: This network meta-analysis provides supporting evidence to the idea that DWI has a higher diagnostic value regarding ischemic stroke among MRI methods, and CTP has a poor diagnostic value among CT methods, which provide therapeutic considerations for Ischemic stroke intervention.

Vertebral artery hypoplasia as an independent risk factor of posterior circulation atherosclerosis and ischemic stroke
Vertebral artery hypoplasia (VAH) is a frequent anatomical variation of vertebral arteries, with emerging evidence suggesting that it contributes to posterior circulation ischemia. However, the relationship between VAH and ischemic stroke remains unknown. Hence, this study aimed to determine the prevalence of VAH in patients diagnosed with acute ischemic stroke who were followed up in a neurology clinic and to determine if it can potentially be a risk factor for atherosclerotic stenosis in vertebrobasilar circulation. This retrospective study included 609 patients diagnosed with acute ischemic stroke between January 1, ...

Imaging-Based Patient Selection and Endovascular Therapy of Ischemic Stroke: A Stratified Meta-Analysis
Abstract: The positive results of recent trials for the treatment of acute ischemic stroke have highlighted the importance of imaging selection before endovascular therapy. We performed a stratified meta-analysis to confirm this new understanding. We searched EMBASE, PubMed, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov in April 2015 for randomized controlled trials evaluating the effect of endovascular treatment in patients with acute ischemic stroke. The meta-analysis was stratified by whether computed tomographic angiography (CTA) was used to select patients. Outcome data were pooled using fixed...

Is carotid sonography a useful tool for predicting functional capabilities in ischemic stroke patients following carotid artery stenting?
Abstract: Carotid stenosis is a major cause of stroke and timely intervention with stenting manipulation can significantly reduce the risk of secondary stroke. The impact of stenting procedures on patient functional capabilities has not yet been explored. The primary aim of this study was to examine associations between periprocedural carotid sonography parameters and post-treatment functional capabilities in stroke patients. Sixty-seven patients who received carotid stenting at 1 angiography laboratory were included. Prestenting and poststenting carotid duplex data were recorded and resistance index (RI) differences at v...

The resolution of carotid arterial thrombus by oral anticoagulation after IV thrombolysis for chemotherapy-induced stroke: A case report
Rationale: Cancer-related stroke has been regarded as an emerging subtype of ischemic event. Acute treatment for this subtype may include the antiplatelet agents, anticoagulants, or endovascular intervention. Patient concerns: A 63-year-old woman with sudden-onset right hemiparesis and conscious change was sent to our emergency department. The patient had underlying sigmoid adenocarcinoma and received chemotherapy FOLFIRI (FOL, folinic acid; F, fluorouracil; and IRI, irinotecan) with targeted therapy cetuximab following lower anterior resection since the diagnosis was made. Diagnoses: Brain magnetic resonance angio...

The diagnostic reliability and validity of noninvasive imaging modalities to assess leptomeningeal collateral flow for ischemic stroke patients: A systematic review and meta-analysis
Leptomeningeal collateral flow (LMF) is associated with infarct area and clinical outcome for ischemic stroke patients. Although LMF can be detected by multiple imaging methods, but their diagnostic performance is uncertain. The aim of this study was to evaluate the diagnostic validity or reliability of noninvasive image methods in assessing LMF. Databases included PubMed, Web of Science, Embase, and Cochrane Library. Original observational cohort studies. Ischemic stroke patients. Different noninvasive image methods to assess LMF. Newcastle–Ottawa Scale to evaluate the quality of the studies; forest pl...

Recurrent migraine with binocular transient vision loss associated with acute stroke: A case report
CONCLUSION: Recurrent migraine with TBVL can be associated with acute stroke. It thus merits urgent evaluation and referral to the relevant department for a better outcome.PMID:34917346 | PMC:PMC8646124 | DOI:10.1016/j.amsu.2021.103062

Added value of systemic inflammation markers in predicting pulmonary infection in stroke patients: A retrospective study by machine learning analysis
This study aimed to develop machine learning (ML)-based predictive models for pulmonary infection. Between January 2008 and April 2021, a retrospective analysis of 1397 stroke patients who had CT angiography from skull to diaphragm (including CT of the chest) within 24 hours of symptom onset. A total of 21 variables were included, and the prediction model of pulmonary infection was established by multiple ML-based algorithms. Risk factors for pulmonary infection were determined by the feature selection method. Area under the curve (AUC) and decision curve analysis were used to determine the model with the best resolut...

Endovascular Coil Embolization for Recurrent Bow Hunter's Stroke
Intern Med. 2022 May 14. doi: 10.2169/internalmedicine.8906-21. Online ahead of print.ABSTRACTBow hunter's stroke is a rare cause of vertebrobasilar infarction. There is no consensus regarding the optimal treatment. We herein report a case of bow hunter's stroke successfully treated by endovascular treatment. A 70-year-old man presented with central vertigo. Magnetic resonance imaging (MRI) showed posterior circulation infarcts. Dynamic angiography revealed thrombus formation and hypoperfusion of the right vertebral artery upon head rotation to the left. Endovascular parent artery occlusion of the right vertebral artery wa...
