A Direct Aspiration First Pass Technique (ADAPT) for acute stroke therapy: a systematic review and meta ‐analysis
ConclusionsADAPT therapy is associated with similar reperfusion rates, clinical outcomes, and complication rates compared to thrombectomy with stent retrievers. However, major limitations of current evidence (ie, retrospective studies and selection bias) indicate a need for adequately powered, multicenter randomized controlled trials to determine the best strategy.This article is protected by copyright.

Presence of the hyperintense acute reperfusion marker on MRI after mechanical thrombectomy for large vessel occlusion is associated with worse early neurological recovery
Conclusions
This preliminary analysis shows that the presence of HARM may be linked to worse neurological recovery 24 hours after thrombectomy. Reperfusion injury may affect the number of patients achieving functional independence after treatment.

Cerebral Autoregulation in Stroke
AbstractPurpose of ReviewCerebral autoregulation (CA) is a mechanism that maintains cerebral blood flow constant despite fluctuations in systemic arterial blood pressure. This review will focus on recent studies that measured CA non-invasively in acute cerebrovascular events, a feature unique to the transcranial Doppler ultrasound. We will summarize the rationale for CA assessment in acute cerebrovascular disorders and specifically evaluate the existing data on the value of CA measures in relation to clinical severity, guiding management decisions, and prognostication.Recent FindingsExisting data suggest that CA is general...

The imperative need to identify stroke risk stratification models for patients with asymptomatic carotid artery stenosis
The optimal management of patients with asymptomatic carotid stenosis (ACS) is controversial. The study by Klarin et al1 provides important novel information that challenges the theory claiming that medical treatment (MT) alone is adequate for the management of all patients with ACS and that prophylactic carotid endarterectomy is not justified in any of these patients.2 Klarin et al1 showed that 112 of 219 pat ients (50%) with radiographically confirmed first-ever carotid-related strokes did actually receive antiplatelet therapy before their stroke, and 121 of 219 patients (55%) received lipid-lowering therapy (most ...

A Non-linear Association Between Total Small Vessel Disease Score and Hemorrhagic Transformation After Ischemic Stroke With Atrial Fibrillation and/or Rheumatic Heart Disease
Background: Previous studies have investigated the association between a single marker of cerebral small vessel disease (SVD) and hemorrhagic transformation (HT). However, the effect of the total SVD burden on HT has not been evaluated yet. We aimed to investigate the association between the total SVD score and HT in ischemic stroke patients with atrial fibrillation (AF) and/or rheumatic heart disease (RHD).
Methods: Ischemic stroke patients with AF and/or RHD admitted within 7 days after onset were enrolled at two hospitals in China. The total SVD score was based on the presence of lacunes, extensive white matter hyperin...

Distribution of ischemic strokes in patients with atrial fibrillation: The FibStroke Study
Conclusions
The timing of AF diagnosis, use of OAC drugs, or the CHA2DS2-VASc score did not affect the distribution of ischemic strokes. Anterior territory strokes were slightly more often located within the left hemisphere.

Simultaneous revascularization of the occluded internal carotid artery using the Solitaire as a workhorse wire during acute ischemic stroke intervention.
CONCLUSION: As the management paradigms of tandem occlusions continue to evolve, this technique may improve outcomes by expediting endovascular intervention. Using the stent retriever wire provides a method of expediting the management of the proximal lesion after addressing the more distal intracranial occlusion first.

Role of Radiological Eye Deviation in Imaging Occult Cases of Acute Large Vessel Occlusion
The recent article from McCluskey et al “Radiological Eye Deviation as a Predictor of Large Vessel Occlusion in Acute Ischaemic Stroke” J of Stroke and Cerebrovasc Dis. 2019; 28:2318-23231 provides valuable information that may lead to early stroke intervention. They found that subjective visual detection of radiographic eye deviation on nonenhanced computed tomography (NECT) brain is strongly associated with large vessel occlusion (LVO). This compelling association may expedite patients for timely angiographic testing and endovascular therapy.

High Monocyte-To-Lymphocyte Ratio Is Associated With Stroke-Associated Pneumonia
Conclusions: Our study showed that higher MLR was significantly associated with SAP in AIS patients. MLR is beneficial for clinicians to recognize patients with a high risk of SAP at an early stage and is an effective way to improve clinical care of SAP patients. Higher MLR could be a helpful and valid biomarker for predicting SAP in clinical practice.

Work satisfaction among neuroradiology staff after receiving follow up reports of thrombectomy stroke patients
by Charlotte Hager, Homan Taufik, Friederike Blum, Andrea Stockero, Martin Wiesmann, Arno Reich, Rebecca May, Omid Nikoubashman
Background and purposeDuring a period of 6 months, we provided our entire neuroradiological staff including physicians, radiographers, and researchers with systematic feedback via email on the further clinical course of stroke patients who underwent mechanical thrombectomy. We analyzed the effects of this feedback on work satisfaction, work meaningfulness and valuation of the therapy among our staff. MethodsOur staff completed two self-reported questionnaires before and after the period of six mon...

Stroke Following Thoracic Endovascular Aortic Repair: Determinants, Short and Long Term Impact
We performed a contemporary assessment of clinical and radiographic factors of stroke after thoracic endovascular aortic repair (TEVAR). Patients undergoing TEVAR from 2006-2017 were identified. We assessed clinical and radiographic data, including preoperative head and neck computed tomography, Doppler ultrasonography and intraoperative angiography. Our primary outcome was stroke after TEVAR. 479 patients underwent TEVAR, mean age 68.1 ±19.5 years, 52.6% male. Indications for TEVAR included aneurysms (n=238, 49.7%) or dissections (n=152, 31.7%).

Natural Language Processing of Radiology Reports to Detect Complications of Ischemic Stroke
ConclusionsOur study demonstrates robust performance and external validity of a core NLP tool kit for identifying both categorical and continuous outcomes of ischemic stroke from unstructured radiographic text data. Medically tailored NLP methods have multiple important big data applications, including scalable electronic phenotyping, augmentation of clinical risk prediction models, and facilitation of automatic alert systems in the hospital setting.
