Carotid Artery Stent Placement and Carotid Endarterectomy: A Challenge for Urgent Treatment after Stroke —Early and 12-Month Outcomes in a Comprehensive Stroke Center
Conclusions CAS placement and CEA seem to offer early safe and feasible secondary stroke prevention treatments in experienced centers, even after major atherosclerotic stroke.

Assessment of longitudinal hippocampal atrophy in the first year after ischemic stroke using automatic segmentation techniques
Publication date: Available online 22 October 2019Source: NeuroImage: ClinicalAuthor(s): Mohamed Salah Khlif, Emilio Werden, Natalia Egorova, Marina Boccardi, Alberto Redolfi, Laura Bird, Amy BrodtmannAbstractWe assessed first-year hippocampal atrophy in stroke patients and healthy controls using manual and automated segmentations: AdaBoost, FIRST (fsl/v5.0.8), FreeSurfer/v5.3 and v6.0, and Subfields (in FreeSurfer/v6.0). We estimated hippocampal volumes in 39 healthy controls and 124 stroke participants at three months, and 38 controls and 113 stroke participants at one year. We used intra-class correlation, concordance, ...

Incidence, Causative Mechanisms, and Anatomic Localization of Stroke in Pituitary Adenoma Patients Treated With Postoperative Radiation Therapy Versus Surgery Alone
Purpose: To assess and compare the incidence of stroke and stroke subtype in pituitary adenoma patients treated with postoperative radiation therapy (RT) and surgery alone.Methods and Materials: A cohort of 462 pituitary adenoma patients treated between 1959 and 2008 at the University Medical Center Groningen in The Netherlands was studied. Radiation therapy was administered in 236 patients. The TOAST (Trial of ORG 10172 in Acute Stroke Treatment) and the Oxfordshire Community Stroke Project classification methods were used to determine causative mechanism and anatomic localization of stroke. Stroke incidences in patients ...

Exploring Carotid Sonographic Parameters Associated With Stroke Risk Among Hypertensive Stroke Patients Compared to Hypertensive Controls
Conclusions— Among hypertensive patients, the common carotid artery diameter and EDV are significantly associated with stroke risk. These findings have implications for development and evaluation of stroke prevention programs.

Validation of fast diffusion kurtosis MRI for imaging acute ischemia in a rodent model of stroke
Diffusion‐weighted imaging (DWI) captures ischemic tissue that is likely to infarct, and has become one of the most widely used acute stroke imaging techniques. Diffusion kurtosis imaging (DKI) has lately been postulated as a complementary MRI method to stratify the heterogeneously damaged DWI lesion. However, the conventional DKI acquisition time is relatively long, limiting its use in the acute stroke setting. Recently, a fast kurtosis mapping method has been demonstrated in fixed brains and control subjects. The fast DKI approach provides mean diffusion and kurtosis measurements under substantially reduced scan time, ...

Completeness of the circle of Willis and risk of ischemic stroke in patients without cerebrovascular disease
Conclusions An incomplete anterior CoW combined with an incomplete posterior CoW is related to future anterior circulation stroke. CoW completeness has no large effect on the relation between asymptomatic ICA stenosis/occlusion and future stroke.

Structurofunctional resting-state networks correlate with motor function in chronic stroke
Conclusion The results demonstrate that changes after a stroke in both intrinsic and network-based structurofunctional correlations at rest are correlated with motor function, underscoring the importance of residual structural connectivity in cortical networks.

Relationship of spontaneous microembolic signals to risk stratification, recurrence, severity, and mortality of ischemic stroke: a prospective study
In conclusion, MES demonstrated a significant correlation with symptomatic carotid disease and a shorter DELAY until monitoring, and could be a predictor for the early recurrence of stroke in the long term.

Predictors of ghost infarct core on baseline computed tomography perfusion in stroke patients with successful recanalization after mechanical thrombectomy
ConclusionsIn stroke patients achieving successful recanalization after MT, time interval from stroke onset to CTP and ischemic core volume are associated with the occurrence of GIC. Patients cannot be excluded from MT solely based on baseline CTP-derived ischemic core volume, especially for patients with a shorter onset time.Key Points• Ghost infarct core (GIC) was found in 15.7% of patients with acute ischemic stroke (AIS) in our study cohort.• GIC was associated with stroke onset time, volumetric parameters derived from CTP, and collateral status indicated by HIR.• Time interval from stroke onset to CTP scan and i...

Incidence of mechanical thrombectomy among stroke patients brought directly to a comprehensive stroke center versus transfer from a primary stroke center in upstate New York
CONCLUSION: Patients transferred from a PSC were more likely to have a worse outcome at time of discharge than those presenting directly to our center. Large volume of completed stroke was a frequent reason for exclusion from thrombectomy. Optimizing stroke protocols to CSC in cases of LVOs may result in better outcomes.PMID:37231646 | DOI:10.1177/15910199231177763

Efficacy and safety of thrombectomy for acute ischaemic stroke in patients with pre-stroke mRS scores of 2-3: Real-world evaluation from an open-label, prospective, multicentre, observational study
CONCLUSION: Intravenous t-PA and especially thrombectomy were safe and effective for the population with pre-stroke disabilities, particularly for patients with low NIHSS scores.PMID:37461387 | DOI:10.1177/15910199231185637
