Clinical Risk Factors and CT Imaging Features of Carotid Atherosclerotic Plaques as Predictors of New Incident Carotid Ischemic Stroke: A Retrospective Cohort Study EXTRACRANIAL VASCULAR
CONCLUSIONS: Our new paradigm of using age ≥75 years, history of hypertension, and carotid maximal wall thickness of >4 mm identified most of the patients with subsequent new carotid stroke in our study. It is simple and may help clinicians choose the patients at greatest risk of developing a carotid infarct, warranting validation with a prospective observational study.

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.

Radiation, Atherosclerotic Risk Factors, and Stroke Risk in Survivors of Pediatric Cancer: A Report From the Childhood Cancer Survivor Study
Conclusion: Young adult pediatric cancer survivors have an increased stroke risk that is associated with CRT in a dose-dependent manner. Atherosclerotic risk factors enhanced this risk and should be treated aggressively.

Possible Morphological Pathomechanisms of Ischemic Stroke in the Posterior Circulation of Patients with Vertebral Artery Hypoplasia
CONCLUSIONIn patients with VAH, the combination of several pathomechanisms of ischemic stroke and the contribution of several risk factors can cause the clinical manifestation of PCS.

Predictors of response to endovascular treatment of posterior circulation stroke
ConclusionsPretreatment determination of the presence or absence of intracranial atherosclerosis can aid management of posterior circulation stroke patients. The absence of intracranial atherosclerosis may have value as a positive selection criterion for endovascular treatment in future trials. The presence of intracranial atherosclerosis could be used as a selection tool in future studies investigating new treatment protocols for this population.

Middle Cerebral Artery Stenosis in Patients with Acute Ischemic Stroke and TIA in Israel BRAIN
CONCLUSIONS: An independent and significant correlation was found between MCA stenosis and vascular risk factors (diabetes mellitus) and vascular diseases, thus emphasizing the similarity of intracranial MCA stenosis and other vascular diseases originating from atherosclerosis. There was no influence of ethnicity on intracranial stenosis in our population.

Visualization of Lenticulostriate Arteries by Flow-Sensitive Black-Blood MR Angiography on a 1.5T MRI System: A Comparative Study between Subjects with and without Stroke BRAIN
CONCLUSIONS: Using FSBB-MRA to visualize LSA branches, we found a significant reduction in the numbers of LSA branches in patients with stroke, and hypertension was inversely related to total LSA length. FSBB is a promising method to investigate the LSA by using 1.5T MR imaging.

Central Aortic Pressure and Pulsatility Index in Acute Ischemic Stroke
CONCLUSIONSTCD PI was significantly related with central aortic pressure, especially PP. The PI in the MCA and BA is closely associated with the pulsatile component of BP in the systemic circulation.

Recanalization and Mortality Rates of Thrombectomy With Stent-Retrievers in Octogenarian Patients with Acute Ischemic Stroke
Conclusions In our series, treatment with stent-retrievers in octogenarians with acute ischemic stroke achieved good rates of recanalization but with a high mortality rate. ICA involvement and revascularization times beyond 6 hours associated to a worse prognosis. These data might be of value in the design of prospective studies evaluating the clinical efficacy of the endovascular treatments in octogenarians.

Thrombus composition in acute ischemic stroke: A histopathological study of thrombus extracted by endovascular retrieval
Conclusion HAS was significantly associated with early phase thrombus composition. This may enable the prediction of thrombus composition and allow for targeted selection of therapeutic modality.

Middle Cerebral Artery Pulsatility Index is Associated with Cognitive Impairment in Lacunar Stroke
CONCLUSIONSPI was associated with the cognitive performance in patients with lacunar infarcts and a lacunar syndrome. An elevated PI may be related to impairment in several cognitive domains. These findings suggest that transcranial Doppler ultrasonography could be an adjunct tool for early diagnosis of cognitive impairment after stroke.

Doppler flow morphology characteristics of epiaortic arteries in aortic valve pathologies: a retrospective study on a cohort of patients with ischemic stroke
ConclusionsWell defined, qualitative Doppler flow characteristics detectable in the CCA and ICA are highly predictive for aortic valve disease. The consideration of these flow characteristics can be useful to streamline diagnostic and therapeutic measures, especially in the outpatient setting.

Risk factors analysis according to regional distribution of white matter hyperintensities in a stroke cohort
ConclusionsDifferent CVRF profiles were significantly related to specific WMH spatial distribution patterns in a large IS cohort.Key Points• An observational study of WMH in a large IS cohort was assessed by a modified visual evaluation.• Different CVRF profiles were significantly related to specific WMH spatial distribution patterns.• Distinct WMH anatomical patterns could be related to different pathophysiological mechanisms.

Patient characteristics associated with delayed neurological improvement following acute ischemic stroke: A systematic review and meta-analysis
CONCLUSIONS: DNI is a phenomenon that is not presently well understood. Lack of uniformity among definitions of DNI hinders efforts to explore DNI and the factors associated with its occurrence. Future studies should work to establish a consensus definition of DNI to determine its causes and significance more accurately.PMID:36597678 | DOI:10.1177/15910199221149787
