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.

Long-Term Outcomes of Stroke or Transient Ischemic Attack after Non-Emergency Percutaneous Coronary Intervention
Elective percutaneous coronary intervention is increasing in volume, which may be due to an increased use of CT coronary angiography as a first-line investigation for the evaluation of chest pain.1,2 Stroke is a debilitating neurological complication with increasing incidence after PCI in recent years, due to an increasing complexity of patients.3 Large observational and randomized controlled studies found that peri-procedural stroke occurred in 0.13-0.4% of unselected patients who underwent PCI.

CT Perfusion Maps Improve Detection of M2-MCA Occlusions in Acute Ischemic Stroke
A growing body of literature supports mechanical thrombectomy-based endovascular therapy for M2-MCA occlusions in eligible patients with acute ischemic stroke (AIS).1 –5 This is because endovascular treatment for M2-MCA occlusions is technically feasible and leads to improved patient outcomes, despite a potential increased risk of hemorrhage.4,5 Not uncommonly, these patients undergo a single or multi-phase CT angiogram (CTA) study for LVO detection. In patient s who present in the late stroke window (6–24 h since last known normal), the CT Perfusion (CTP) study is generally performed along with a CTA study to aid in patient triage.

Hypoperfusion Intensity Ratio is Associated with Stroke Mechanism in Patients Undergoing Mechanical Thrombectomy
Hypoperfusion Intensity Ratio (HIR), defined as Tmax>10s/Tmax>6s on computed tomography perfusion (CTP), and stroke mechanisms have been independently correlated with angiographic collaterals and patient outcomes. Slowly developing atherosclerotic stenosis may foster collateral development, whereas cardioembolic occlusion may occur before collaterals mature. We hypothesized that favorable HIR is associated with large artery atherosclerosis (LAA) stroke mechanism and good clinical outcome.

Feasibility of deconvolution-based multiphase CT angiography perfusion maps in acute ischemic stroke: Simulation and concordance with CT perfusion
Integration of CT perfusion (CTP) with requisite non-contrast CT and CT angiography (CTA) stroke imaging may allow efficient stroke lesion volume measurement. Using surrogate images from CTP, we simulated the feasibility of using multiphase CTA (mCTA) to generate perfusion maps and assess target mismatch profiles.

Intravenous Tissue Plasminogen Activator Therapy for an Acute Ischemic Stroke Patient with Later Diagnosed Unilateral Moyamoya Syndrome
We report the use of intravenous tissue plasminogen activator (t-PA) therapy in a 38-year-old patient who was later diagnosed with unilateral moyamoya syndrome. The patient had a sudden onset of unconsciousness, vomiting, dysarthria, and tetraparesis. A neurologic examination revealed consciousness disturbance, right central facial nerve palsy, dysarthria, and tetraparesis with bilateral exotropia and horizontal gaze palsy. A magnetic resonance imaging scan on admission did not reveal fresh cerebral infarction or hemorrhage, but magnetic resonance angiography revealed severe stenosis at the terminal portion of left interna...

Sex Differences in Revascularization Interventions after Acute Ischemic Stroke
Conclusions: Over the last decade, women hospitalized for AIS in the United States were less likely than men to receive cerebrovascular and cardiac reperfusion therapies. However, the IV tPA treatment sex disparity may have been eliminated.

Spontaneous Isolated Posterior Inferior Cerebellar Artery Dissection: Rare but Underdiagnosed Cause of Ischemic Stroke
Conclusions: Clinical manifestations in ischemic type of spontaneous isolated PICAD were similar to those of intracranial vertebral artery dissection. Clinical course was relatively stable and benign. SWI was more helpful to suspect abnormality of posterior inferior cerebellar artery than conventional MRI or magnetic resonance angiography in our small series. Cerebral angiography is recommended in patients with clinically suspected spontaneous isolated PICAD for definite diagnosis.

Demographic and Clinical Predictors of Leptomeningeal Collaterals in Stroke Patients
Background: Leptomeningeal collaterals improve outcome after stroke, including reduction of hemorrhagic complications after thrombolytic or endovascular therapy, smaller infarct size, and reduction in symptoms at follow-up evaluation. The purpose of this study was to determine the demographic and clinical variables that are associated with a greater degree of cerebral collaterals.Methods: Clinical data of patients presenting with M1 occlusions of the middle cerebral artery (MCA) and associated computed tomography angiography studies after admission from 3 separate institutions were retrospectively compiled (n = 82). Occl...

Clot Characteristics on Computed Tomography and Response to Thrombolysis in Acute Middle Cerebral Artery Stroke
Clinical and computer tomography angiography (CTA) correlates of hyperdense middle cerebral artery sign (HMCAS) and dot sign were revisited in patients treated for acute MCA stroke. Temporal evolution of these signs over 24 hours was assessed quantitatively by density (Hounsfield unit [HU]) measurements.
