Flow diversion within seven days after stroke onset is associated with favorable outcome in anterior circulation stroke
Publication date: Available online 21 July 2017 Source:Journal of Clinical Neuroscience Author(s): Fei Wu, Wenjie Cao, Yifeng Ling, Lumeng Yang, Xin Cheng, Qiang Dong Anterior cerebral artery (ACA) flow diversion (FD), defined as ipsilateral mean velocity (MV) of at least 30% greater than the contralateral artery, could be seen an indirect sign of leptomeningeal collateralization in the setting of middle cerebral artery occlusion. The purpose of the study was to evaluate the association between dynamic FD and functional outcome in acute anterior stroke patients with large artery occlusion. Acute middle cerebral artery (MC...

Association between nocturnal blood pressure variation and wake-up ischemic stroke
In this study, we used ambulatory blood pressure monitoring (ABPM) to examine the association between WUS and variation in nocturnal BP. A total of 369 patients with ischemic stroke within one week were consecutively enrolled. ABPM was applied 1–2weeks after the ictus because of possible reactive increments of BP; antihypertensive medications were delayed until ABPM. Patients were classified into two groups: WUS and non-WUS. Clinical characteristics, including ABPM parameters, were compared. Sixty-seven (18%) patients had WUS. In univariate analysis, patients with WUS had more severe stroke symptoms than patients with no...

Perioperative stroke after cerebral aneurysm clipping: Risk factors and postoperative impact
This study assesses patient-specific independent predictors of perioperative stroke in relation to surgical aneurysm clipping. Additionally, this study evaluates the postoperative complications of stroke. We performed a retrospective chart review of 437 patients with ruptured and unruptured intracranial aneurysms, which underwent surgical clipping from 2006 to 2013. Multivariate logistical regression was utilized to assess the effect of age, race, gender, subarachnoid hemorrhage, Hunt and Hess (H/H) grade, aneurysm location, and intraoperative somatosensory evoked potentials (SSEPs) changes on the frequency of perioperativ...

Stroke prediction with CHA2DS2-VASc score in patients with mesenteric ischemia without atrial fibrillation-insights from a nationwide cohort
Conclusions A higher CHA2DS2-VASc score is demonstrated to be associated with an increased risk of ischemic stroke among patients with mesenteric ischemia without comorbid AF.

Neuroinflammation responses after subarachnoid hemorrhage: A review
Publication date: August 2017 Source:Journal of Clinical Neuroscience, Volume 42 Author(s): Vera Zhiyuan Zheng, George Kwok Chu Wong Subarachnoid hemorrhage (SAH) is an important cause of stroke mortality and morbidity, especially in the young stroke population. Recent evidences indicate that neuroinflammation plays a critical role in both early brain injury and the delayed brain deterioration after SAH, including cellular and molecular components. Cerebral vasospasm (CV) can lead to death after SAH and independently correlated with poor outcome. Neuroinflammation is evidenced to contribute to the etiology of vasospasm. B...

Assessment of healthcare personnel knowledge of stroke care at a large referral hospital in sub-Saharan Africa – A survey based approach
Publication date: August 2017 Source:Journal of Clinical Neuroscience, Volume 42 Author(s): Chen Lin, Ravi Vakani, Peter Kussin, Mary Guhwe, Alfredo E. Farjat, Kingshuk Choudhury, David Renner, Chrispine Oduor, Carmelo Graffagnino There is no published literature regarding sub-Saharan health-care providers’ understanding of stroke management patterns. Understanding current stroke management knowledge is important in formulating future education opportunities for providers to optimize patient outcomes. A cross-sectional survey of acute stroke diagnosis, hospital management, and secondary prevention questions was administ...

Carotid artery disease and perioperative stroke risk after surgical aortic valve replacement: A nationwide inpatient sample analysis
In conclusion, perioperative stroke risk has remained more or less constant despite advancements in surgical techniques with risk having gone up in patients <65years of age. CS and cerebral arterial occlusion significantly increase stroke risk following SAVR. Improved patient selection with pre-operative risk stratification and institution of preventive strategies are necessary to improve operative outcomes following SAVR.

Hypertrophic olivary degeneration after cerebellar hemorrhage
We present a striking example of hypertrophic olivary degeneration after cerebellar hemorrhage. This case highlights some important teaching points: unique response of the inferior olivary nucleus to de-afferentation, anatomy of Mollaret’s triangle and clinical manifestations of disruption in Mollaret’s triangle. The purpose of this teaching case is to highlight a rare but important post-stroke complication.

Reversible hemispheric hypoperfusion in two cases of SMART syndrome
We present two cases demonstrating reversible hemispheric hypoperfusion. Case 1 presented with left hemispheric symptoms following previous similar episodes. CT perfusion (CTP) demonstrated reversible hemispheric hypoperfusion; subsequent investigations were consistent with SMART syndrome. Case 2 presented following the third episode of a hemispheric syndrome with near-identical CTP abnormalities. L-arginine was administered with rapid reversal of clinical and CTP abnormalities. We conclude that SMART syndrome may demonstrate significant hypoperfusion on hyperacute CTP without subsequent infarction. Impaired cerebrovascula...

Association of ischemic and hemorrhagic strokes hospital admission with extreme temperature in Nanchang, China —A case-crossover study
This study suggests that extreme high temperature might be a risk factor for both hemorrhagic and ischemic strokes, and that extreme low temperature might be a risk factor of hemorrhagic stroke. Further studies are necessary in order to clarify this relationship and provide evidence for stroke prevention.

Prognostic value of peripheral leukocyte counts and plasma glucose in intracerebral haemorrhage
Conclusion These results suggest that a logistic regression model using low admission glucose and low total leukocyte count may be markers of better prognosis in acute haemorrhagic stroke with a differential effect between sexes.

Risk of stroke in imaging-proven subclavian steal syndrome
Publication date: July 2017 Source:Journal of Clinical Neuroscience, Volume 41 Author(s): Xia Tan, Harrison Xiao Bai, Zhili Wang, Li Yang To determine the risk of stroke in patients with subclavian steal syndrome (SSS). We identified 165 patients with imaging-provenSSS from two hospitals. Demographic, clinical and imaging data were retrospectively collected. Patients were followed up for stroke events. Stroke occurred in 43 patients with a median follow-up of 28months. Seven of these cases were identified prospectively and 36 cases retrospectively. On multivariate analysis, presence of symptoms at presentation (p =0.029) ...
