Varicella-Associated Stroke
A previously healthy, unimmunized 11-month-old boy presented with acute right-sided weakness. On the day of presentation, his mother noted that his right arm and leg seemed to be weak when she woke him from his usual afternoon nap. Evaluation at an urgent care center confirmed right-sided facial weakness, decreased strength and movement of his right upper and lower extremities, and a lack of right-sided support in a sitting position. Computed tomography of the head without contrast was normal. He was transferred to a regional care center where head magnetic resonance imaging and magnetic resonance angiography demonstrated ...

Thrombus Enhancement Is a Predictor of Clinical Outcome in Acute Ischemic Stroke after Mechanical Thrombectomy
Conclusions: CE of thrombi – especially in a range from over 18.4 to 40.35 Hounsfield Units – is an independent predictor of poor clinical outcome in patients undergoing MT due to acute middle cerebral artery occlusion.Cerebrovasc Dis 2018;46:270 –278

Deep Venous Thrombosis with Decreased Cerebral Blood Flow to the Thalamus was Completely Restored by Factor Xa Inhibitor
Background: Cerebral venous thrombosis is rare and an uncommon cause of stroke and has diverse etiologies and varied clinical presentations. Here, we report 2 cases of deep cerebral venous thrombosis. Case Description: A 64-year-old woman presented with cerebral venous thrombosis due to a hypercoagulable state associated with ovarian tumor. On initial fluid-attenuated inversion recovery and diffusion-weighted imaging, there was a diffuse high-intensity lesion in the bilateral thalamus. Computed tomography angiography showed occlusion of the straight sinus, vein of Galen, and internal cerebral vein.

CT-based Higher Thrombus Density is associated with Secondary Embolism during Mechanical Thrombectomy: A Preliminary Observation
This study addresses a potential relationship between thrombus density on preinterventional computed tomography (CT) and the occurrence of SE. Methods: We reviewed anterior circulation AIS patients who underwent MT from July 2015 to January 2019 in our center. Thrombus density was measured in Hounsfield Units (HU) on 1-mm and 5-mm preinterventional nonenhanced CT (NECT).

Association between Epicardial Adipose Tissue and Embolic Stroke after Catheter Ablation of Atrial Fibrillation
ConclusionLarger peri ‐atrial EAT volume, in addition to prior TE and lower CCr, was independently associated with post‐ablation ES regardless of AF recurrence and CHA2DS2‐VASc score. (ClinicalTrials.gov number, NCT03479073)This article is protected by copyright. All rights reserved.

Computed Tomography Perfusion Showing Cerebral Hypoperfusion in a Patient with Acute Cerebral Venous Sinus Thrombosis —A Case Report
We report the case of a patient with acute CVST, showing perfusion abnormalities on computed tomography perfusion with perfusion defect in the relevant hemisphere. The defect was found in a region adjacent to the occluded sinus and was not corresponding to an arterial territory. To the best of our knowledge this is the first ever report on CT perfusion abnormalities few hours after acute symptom onset in CVST.

Intracranial Aneurysms After Intravenous Thrombolysis in Patient with Atrial Myxoma: A Case Study
We administered intravenous thrombolytic therapy to a 51-year-old female patient with a 101-min stroke onset. The patient was unconscious during the manifestation of symptoms. Computed tomography angiography examination of the intracranial artery at the time of admission suggested that the left middle cerebral artery was occluded. The patient regained consciousness after the intravenous thrombolytic treatment was administered. On an urgent cerebral angiography, it was revealed that the recanalization of the left middle cerebral artery was successful.

Computed tomography perfusion in patients of stroke with left ventricular assist device
AbstractLeft ventricular assist devices (LVAD) are widely applied for patients with severe heart failure as a bridge to heart transplantation as well as destination therapy. Patients with implanted LVAD have an increased risk of cerebral thrombosis and computed tomographic perfusion (CTP) has the potential to be performed for early diagnosis and treatment of acute ischemic stroke (AIS), including interventional thrombectomy. Here, we report our series of CTP examination in patients having suspected AIS after LVAD implantation. We retrospectively investigated 33 contrast-enhanced CTPs from January 2017 to December 2018 whic...

Ipsilateral Vocal Cord Paralysis After Acute Anterior Ischemic Stroke
CONCLUSION: Our case is a rare case of transient ipsilateral vocal cord paralysis associated with anterior unilateral cerebral ischemia. The paralysis resolved with improvement of the cerebral ischemic penumbra.PMID:33635769 | DOI:10.7812/TPP/20.104

Questions on Predicting Early Neurological Deterioration in Patients With Minor Stroke and Large-Vessel Occlusion —Reply
In Reply We thank Ospel and colleagues for their thoughtful comments on our article showing that more proximal occlusion and greater thrombus length predict early neurological deterioration of ischemic origin (ENDi) in patients with acute minor ischemic stroke with large-vessel occlusion treated with intravenous thrombolysis, with implications regarding how to best manage these patients. Although the precise pathophysiological links between more proximal occlusion, a longer thrombus, and ENDi are uncertain, we fully agree that a leading hypothesis is in situ thrombus extension leading to secondary hemodynamic compromise vi...

Can a 'microwave helmet' really detect strokes?
Conclusion This study has shown that haemorrhagic strokes could potentially be distinguished from ischaemic strokes by analysing microwave scattering measurements. While the two types of stroke can already be accurately diagnosed by CT or MRI scans in hospital, the “microwave helmet” development is important because it could potentially be used before someone arrives in hospital. This would avoid any time delay and allow people with ischaemic stroke to receive the anti-clotting medication that they need as soon as possible, potentially reducing the extent of damage the stroke causes. The technique isn’t perfect ye...

Neurological Involvement in Primary Systemic Vasculitis
Conclusion Neurological involvement is a common complication of PSV (Table 1), and neurologists play an important role in the identification and diagnosis of PSV patients with otherwise unexplained neurological symptoms as their chief complaint. This article summarizes the neurological manifestations of PSV and hopes to improve neuroscientists' understanding of this broad range of diseases. TABLE 1 Table 1. Common CNS and PNS involvements of primary systemic vasculitis. Author Contributions SZ conceived the article and wrote the manuscript. DY and GT reviewed and edited the manuscript. All authors ...
