Outcome Differences between Intra-Arterial Iso- and Low-Osmolality Iodinated Radiographic Contrast Media in the Interventional Management of Stroke III Trial INTERVENTIONAL
CONCLUSIONS: While data favoring the use of iso-osmolal iodixanol for reperfusion of M1 occlusion following IV rtPA are inconclusive, potential pathophysiologic mechanisms suggesting clinical benefit warrant further investigation.

Delayed subarachnoid hemorrhage 7 years after cerebellar infarction from traumatic vertebral artery dissection
Vertebral artery dissection (VAD) is an important cause of ischemic stroke and subarachnoid hemorrhage (SAH). Dissections presenting with ischemia rarely cause SAH after more than a few hours, especially without radiographic evidence of pseudoaneurysm. We successfully treated a patient for persistent vessel injury presenting with SAH 7 years after presenting with extracranial subocclusive dissection of the right vertebral artery and an associated right posterior inferior cerebellar artery stroke. This is one of only three reported cases of delayed SAH occurring more than 2 weeks after an initial ischemic presenta...

Depression one year after hemorrhagic stroke is associated with late worsening of  outcomes.
CONCLUSION: This is the first study to investigate depression one year after ICH. Post-ICH depression was common and associated with late worsening of disability unrelated to initial hemorrhage severity. Further research is needed to understand whether depression is caused by worsened disability, or whether the converse is true. PMID: 28505996 [PubMed - as supplied by publisher]

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.

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...

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...

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.

Clinical risk predictors for cerebral hyperperfusion syndrome after carotid endarterectomy
Conclusions Independent, prospective monitoring of a large cohort of CEA cases identified a brief time interval between ischaemic symptoms and endarterectomy as the clearest risk factor for CHS.

Prospective, Randomized, Open-Label Phase II Trial on Concomitant Intraventricular Fibrinolysis and Low-Frequency Rotation After Severe Subarachnoid Hemorrhage Clinical Sciences
Conclusions— Despite the ineffectiveness on reduction of delayed cerebral ischemia or poor functional outcome, intraventricular fibrinolysis and kinetic therapy seems to be a safe and effective concept for therapeutic reduction of subarachnoid clot in a patient collective experiencing predominately severe subarachnoid hemorrhage. Therefore, future studies should investigate this treatment in a larger patient collective with a lower degree of primary brain injury and until full clot clearance on serial imaging.

Adult Moyamoya Disease in an Urban Center in the United States Is Associated With a High Burden of Watershed Ischemia Stroke
Conclusions We observed a high burden of ischemia, mostly watershed pattern on neuroimaging in our adult moyamoya disease patients. Long-term monitoring of adult moyamoya disease patients in the United States would be useful to better understand the natural history of this condition.

Prediction of intracerebral haemorrhage expansion with clinical, laboratory, pharmacologic, and noncontrast radiographic variables
ConclusionClinical and noncontrast radiographic variables only weakly predict hematoma expansion. Examination of other indicators, such as computed tomographic angiography contrast extravasation (the ‘spot sign’), may prove more valuable in acute intracerebral haemorrhage care.

Flat-Panel Computed Tomography (DYNA-CT) in Neuroradiology. From High-Resolution Imaging of Implants to One-Stop-Shopping for Acute Stroke
Abstract Originally aimed at improving standard radiography by providing higher absorption efficiency and a wider dynamic range, flat-panel detector technology has meanwhile got widely accepted in the neuroradiological community. Especially flat-panel detector computed tomography (FD-CT) using rotational C-arm mounted flat-panel detector technology is capable of volumetric imaging with a high spatial resolution. By providing CT-like images of the brain within the angio suite, FD-CT is able to rapidly visualize hemorrhage and may thus improve complication management without the need of patient transfer. As “Angio...

Pediatric Cortical Vein Thrombosis: Frequency and Association With Venous Infarction Brief Reports
Conclusions— In our cohort, CVT was significantly associated with seizures at presentation, hemorrhage and restricted diffusion on acute imaging, as well as neurological disability and venous infarction at follow-up. Involvement of cortical veins in cerebral sinovenous thrombosis is associated with an increased risk of infarction and adverse outcome in children.
