A Systemized Stroke Code Significantly Reduced Time Intervals for using Intravenous Tissue Plasminogen Activator under Magnetic Resonance Imaging Screening
A stroke code can shorten time intervals until intravenous tissue plasminogen activator (IV t-PA) treatment in acute ischemic stroke (AIS). Recently, several reports demonstrated that magnetic resonance imaging (MRI)–based thrombolysis had reduced complications and improved outcomes in AIS despite longer processing compared with computed tomography (CT)–based thrombolysis.
Conclusion: These findings indicate that AS is associated with a high prevalence of SBI, and that the CHA2DS2-VASc score and eGFR are useful for risk stratification.Cerebrovasc Dis Extra 2020;10:116 –123
We report a case of a young woman with a left middle cerebral artery (MCA) ischemic stroke. The patient had history of HIV-1 infection, with periods of therapeutic non-compliance. Initial computed tomography (CT) imaging studies showed stenosis of the M1 segment of the left MCA, and magnetic resonance imaging (MRI) confirmed infarction of the MCA territory. Serial transcranial Doppler ultrasound revealed progressive occlusion of the MCA and stenosis of the left anterior cerebral artery. Systemic investigation for other causes of stroke was normal. Lumbar puncture revealed a mildly inflammatory cerebrospinal fluid, and HSV-...
We report 4 cases of acute ischemic cortical strokes presenting as hemichorea, with the infarction being limited to the parietal and insular cortex in perfusion computed tomography scans and magnetic resonance imaging.
The importance of quick door-to-needle times for patients with focal cerebral ischaemia who are candidates for thrombolysis, and the emergence of mechanical thrombectomy as an effective treatment for large vessel occlusion ischaemic stroke, underlines the importance of early imaging and timely intervention. In this article we cover the main imaging modalities, including computed tomography (CT), CT angiography, magnetic resonance imaging, digital subtraction angiography and perfusion imaging.
This article summarizes the latest research on this topic and provides an approach to clinical practice to use cardiac imaging after stroke.Recent FindingsEchocardiography remains the primary imaging method for cardiac work-up after stroke. Recent echocardiography studies further demonstrated promising results regarding the prediction of non-permanent atrial fibrillation after ischemic stroke. Cardiac magnetic resonance imaging and computed tomography have been tested for their diagnostic value, in particular in patients with cryptogenic stroke, and can be considered as second line methods, providing complementary informat...
Conclusions: In this MT cohort study, MMP-9 level at H6 predicts infarct growth and hemorrhagic transformation.
BACKGROUND Patients with blunt cerebrovascular injuries are at risk of thromboembolic stroke. Although primary prevention with antithrombotic therapy is widely used in this setting, its effectiveness is not well defined and requires further investigation. The aim of this study was to evaluate the utility of magnetic resonance imaging (MRI)–detected ischemic brain lesions as a possible future outcome for randomized clinical trials in this patient population. METHODS This prospective observational study included 20 adult blunt trauma patients admitted to a level I trauma center with a screening neck CTA showing ex...
CONCLUSIONS: In the present cases, although ischemic stroke was serious and precluded surgical indication for ATAAD, carotid artery stenting before surgery for ATAAD resulted in good clinical outcomes. Performing carotid artery stenting before surgery for ATAAD is challenging but achievable, and is a valid treatment option depending on the individual cases.

CONCLUSION: Not the whole process of coagulation function is associated with spontaneous HT. Prolonged TT, which may indicate an extension of the last step of the coagulation process, is independently and inversely associated with spontaneous HT in patients with acute ischemic stroke.
