Effective Mechanical Thrombectomy in a Patient with Hyperacute Ischemic Stroke Associated with Cardiac Myxoma
We describe a patient with hyperacute stroke caused by cardiac myxoma who had a good outcome with rapid recanalization through mechanical thrombectomy. A 46-year-old man was admitted with acute symptoms of right side hemiplegia and global aphasia. Brain computed tomography (CT) angiography showed a T occlusion of the left internal carotid artery. Intravenous recombinant tissue plasminogen activator was administered. However, his clinical symptoms did not improve. Thus, we performed endovascular treatment and had a successful outcome. A pathologic examination of the retrieved clot revealed a tumor emboli from a cardiac myxo...

The “DeyeCOM Sign”: Predictive Value in Acute Stroke Code Evaluations
Rapid diagnosis in stroke is critical. Computed tomography is often performed initially, even before a neurologic examination. Gaze deviation has been correlated with stroke diagnosis in some cohorts. Conjugate gaze deviation on stroke code imaging, the “DeyeCOM sign,” may have emergency stroke care implications.

Sulcal Effacement With Preserved Gray-White Junction: A Sign of Reversible Ischemia Brief Reports
Conclusions— Sulcal effacement with preserved gray–white delineation is occasionally visualized in patients with proximal occlusion strokes, relates to robust leptomeningeal collaterals, and indicates preserved underlying parenchyma. ISE should not be used to exclude patients from thrombectomy.

The Clinical Relevance of Microbleeds in Stroke study (CROMIS‐2): rationale, design, and methods
Background and rationaleThe increasing use of oral anticoagulants, mostly to prevent ischemic stroke due to atrial fibrillation in an ageing population, has been associated with a fivefold increased incidence of oral anticoagulant‐associated intracerebral hemorrhage: a rare, serious, and unpredictable complication. We hypothesize that cerebral microbleeds and other markers of cerebral small vessel disease on magnetic resonance imaging, and genetic polymorphisms (e.g. influencing cerebral small vessel integrity or anticoagulation stability), are associated with an increased risk of oral anticoagulant‐associated intracer...

Using Radiological Data to Estimate Ischemic Stroke Severity
Risk-adjusted poststroke mortality has been proposed for use as a measure of stroke care quality. Although valid measures of stroke severity (e.g., the National Institutes of Health Stroke Scale [NIHSS]) are not typically available in administrative datasets, radiology reports are often available within electronic health records. We sought to examine whether admission head computed tomography data could be used to estimate stroke severity.

Higher Insulin Resistance Level is Associated with Worse Clinical Response in Acute Ischemic Stroke Patients Treated with Intravenous Thrombolysis
Abstract Insulin resistance is linked to atherosclerotic cardiovascular diseases and stroke. We investigated whether there is a relationship between insulin resistance and clinical findings and outcomes of acute ischemic stroke patients treated with intravenous thrombolysis. In our study, 180 acute ischemic stroke non-diabetic patients treated with intravenous recombinant tissue-type plasminogen activator (iv rt-PA) were evaluated for insulin resistance assessed by homeostasis model assessment insulin resistance (HOMA-IR). The threshold for HOMA-IR was determined as 2.7. Patients were grouped as HOMA-IR > 2...

Intra-Arterial Therapy and Post-Treatment Infarct Volumes: Insights From the ESCAPE Randomized Controlled Trial Clinical Sciences
Conclusions— These results support the primary results of the ESCAPE trial and show that the biological underpinning of the success of endovascular therapy is a reduction in infarct volume. Clinical Trial Registration— URL: http://www.clinicaltrials.gov. Unique identifier: NCT01778335.

Inter-Rater Variability for Evaluation of ASPECT Score Between a Neurologist and Neuroradiologist in Acute Stroke Patients (P6.020)
Conclusion Inter-rater agreement of evaluation early acute CT ischemic changes in acute-stroke patients between a neurologist and neuroradiologist was almost perfect. That could improve management of the acute stroke and mechanical thrombectomy care. It would support the faster activation of the thrombectomy team, leading to shorter door-to-needle- times and eventually, better outcomes.Disclosure: Dr. Kral has nothing to disclose.

Multidisciplinar Team Ability to Decrease Door-To-Needle Time in Acute Ischemic Stroke - A Single Center Saudi Experience (P6.053)
Conclusions: Implementation of modified stroke code process utilizing quality improvement paradigm of PDSA cycles have resulted in significant decrease in door-to-needle time for IV thrombolysis. Although, the target DTN of 60 minutes was not reached, the trend is favorable with improved outcomes.

Prediction of Blood-Brain Barrier Disruption and Intracerebral Hemorrhagic Infarction Using Arterial Spin-Labeling Magnetic Resonance Imaging Clinical Sciences
Background and Purpose—Arterial spin-labeling magnetic resonance imaging is sensitive for detecting hyperemic lesions (HLs) in patients with acute ischemic stroke. We evaluated whether HLs could predict blood–brain barrier (BBB) disruption and hemorrhagic transformation (HT) in acute ischemic stroke patients.Methods—In a retrospective study, arterial spin-labeling was performed within 6 hours of symptom onset before revascularization treatment in 25 patients with anterior circulation large vessel occlusion on baseline magnetic resonance angiography. All patients underwent angiographic procedures intended for endovasc...

Retinal and Ophthalmic Artery Studies in Ischemic Stroke Patients Using Fundus Photography and Transcranial Doppler Methods (P4.252)
Conclusions:Our study in a robust sample of non-severe stroke patients showed that abnormal retinal AVR is strongly associated with IS patients even after accounting for traditional risk factors. OA-TCD studies, on the other hand, did not have significant associations with stroke group.Disclosure: Dr. Patil has nothing to disclose. Dr. Narayan has nothing to disclose.

Neurons Over Nephrons Clinical Sciences
Background and Purpose—Because of the perceived risk of contrast-induced acute kidney injury (AKI), many centers require pre-imaging serum creatinine levels, potentially delaying care. We performed a systematic review and meta-analysis evaluating AKI rates in patients with acute ischemic stroke receiving computed tomographic angiography (CTA) and computed tomographic perfusion (CTP).Methods—We searched MEDLINE, EMBASE, and the Web of Science through December 2016 for studies reporting on AKI in patients with acute ischemic stroke receiving CTA/CTP. Using a random-effects model, estimates were pooled across studies. Out...

Comments on Validation of Serial Alberta Stroke Program Early CT Score as an Outcome Predictor in Thrombolyzed Stroke Patients
We were interested to read the article by Kong et  al that was published in the Journal of Stroke and Cerebrovascular Diseases in June 2017.1 The authors aimed to assess the validity of the serial Alberta Stroke Program Early CT Score (ASPECTS) in predicting unfavorable outcomes in thrombolyzed stroke patients. The results have demonstrated that 2 4-hour ASPECTS on computed tomography and change in ASPECTS (between the baseline and 24-hour computed tomography) can predict accurately functional outcome in the patients.
