Pretreatment Blood-Brain Barrier Damage and Post-Treatment Intracranial Hemorrhage in Patients Receiving Intravenous Tissue-Type Plasminogen Activator Clinical Sciences
Conclusions— A perfusion-weighted imaging–derived index of blood–brain barrier damage measured before intravenous tissue-type plasminogen activator is given is associated with the severity of ICH after treatment in patients with acute ischemic stroke.

Impaired Glymphatic Perfusion After Strokes Revealed by Contrast-Enhanced MRI: A New Target for Fibrinolysis? Brief Reports
Conclusions— SAH and acute ischemic stroke significantly impair the glymphatic system perfusion. In these contexts, injection of tissue-type plasminogen activator either intracerebroventricularly to clear perivascular spaces (for SAH) or intravenously to restore arterial patency (for ischemic stroke) may improve glymphatic function.

Imaging in acute stroke.
Authors: Eswaradass P, Appireddy R, Evans J, Tham C, Dey S, Najm M, Menon BK Abstract INTRODUCTION: Stroke is the third leading cause of death and disability in Canada. In the hyperacute stroke setting, the treating physician must make a time critical decision on the treatment of each patient. Recent advances in imaging help the treating physician identify the subgroup of patients eligible for acute treatment of ischaemic stroke. AREAS COVERED: In this review we will discuss Non-Contrast Computed Tomography (NCCT), CT-Angiography (CTA), and CT-Perfusion (CTP) in assessment of patients with acute ischaemic strok...

Cerebral venous collaterals: a new fort for fighting ischemic stroke?
Publication date: Available online 2 December 2017 Source:Progress in Neurobiology Author(s): Lu-sha Tong, Zhen-ni Guo, Yi-bo Ou, Yan-nan Yu, Xiao-cheng Zhang, Jiping Tang, John H. Zhang, Min Lou Stroke therapy has entered a new era highlighted by the use of endovascular therapy in addition to intravenous thrombolysis. However, the efficacy of current therapeutic regimens might be reduced by their associated adverse events. For example, over-reperfusion and futile recanalization may lead to large infarct, brain swelling, hemorrhagic complication and neurological deterioration. The traditional pathophysiological understand...

Variability of Stroke Patients Meeting Endovascular Stroke Trial Criteria in a Non-Clinical Trial Setting
Conclusions The proportion of patients with acute stroke and large vessel occlusion presenting within eight hours that would meet radiological criteria for endovascular stroke trials varies considerably (62-100%) in a cohort outside of clinical trials from an academic comprehensive stroke center. Thus, the radiological criteria used for candidate selection in daily practice will greatly influence the proportion of patients treated with endovascular therapy.

Rule-based natural language processing for automation of stroke data extraction: a validation study
ConclusionsRule-based NLP has a moderate to good performance for stroke-related data extraction from free-text imaging reports. The algorithm ’s accuracy was affected by inconsistent report styles and lexicon among reporting radiologists.

Ischemic Conditioning Is Safe and Effective for Octo- and Nonagenarians in Stroke Prevention and Treatment
The objective of this study was to evaluate the safety and effectiveness of BAIPC in reducing stroke recurrence in octo- and nonagenarian patients with SIAS. Fifty-eight patients with SIAS were enrolled in this randomized controlled prospective study for 180 consecutive days. All patients enrolled in the study received standard medical management. Patients in the BAIPC group (n = 30) underwent 5 cycles consisting of bilateral arm ischemia followed by reperfusion for 5 min each twice daily. Those in the control group (n = 28) underwent sham-BAIPC twice daily. Blood pressure, heart rate, local skin status, plasma m...

Stroke etiology and collaterals: atheroembolic strokes have greater collateral recruitment than cardioembolic strokes
ConclusionsAtheroembolic strokes seem to be associated with better collateral flow compared to cardioembolic strokes. This may in part explain the worse outcomes of AF‐related stroke.

Leukoaraiosis as an outcome predictor in the acute and subacute phases of stroke.
Authors: Fierini F, Poggesi A, Pantoni L Abstract INTRODUCTION: Leukoaraiosis (LA) is one of the neuroimaging features of cerebral small vessel disease and is associated with poor long-term prognosis. Areas covered: This narrative review focuses on the predictive role of LA on the evolution of the ischemic brain damage and on the clinical outcome in the subacute phase of stroke and in the short-term period afterwards. Expert commentary: In acute stroke, LA is associated with a less favorable fate of brain infarct and is a marker of increased risk of thrombolysis-related hemorrhagic transformation. The impaired cerebra...

Cerebrovascular recovery after stroke with individual and combined losartan and captopril treatment of SHRsp.
Abstract We assessed whether the superior restoration of cerebrovascular function after hemorrhagic stroke by losartan versus captopril treatment was due to better BP, uremia, uricaemia, or aldosterone control in Kyoto Wistar stroke-prone-hypertensive rats and evaluated whether elevated angiotensin II (A2) levels enhanced the effectiveness of losartan treatment. Constriction was studied in the middle cerebral arteries (MCAs) using a pressure myograph. Post-stroke survival increased from 21 to 310 and 189days respectively with losartan and captopril treatment. Neither treatment reduced BP, both reversed uremia and ...
