OBJECTIVES: To determine if sex was an effect modifier in a pooled analysis of asymptomatic patients from CREST and ACT I. MATERIALS AND METHODS: We analyzed data from 2544 patients aged <80 with ≥70% asymptomatic carotid stenosis randomized to CAS or CEA (nCREST =1091; nACT-1 =1453). The pre-specified primary endpoint in both trials was any stroke, myocardial infarction or death during the peri-procedural period, or ipsilateral stroke within 4 years of randomization...

BACKGROUND: Connexin 43 (Cx43) plays a crucial role in mediating intracellular communication and facitating the interaction between exosomes and recipient cells. This study investigates whether the activation of cAMP/protein kinase A (PKA) can regulate exosomal Cx43 expression and contribute to the functional recovery following ischemia-reperfusion (I/R) injury. METHODS: An intraluminal vascular occlusion was performed on Lewis rats to simulate I/R injury. Concurrently, a PKA activator (8-Bromo-cAMP, 5 mg/kg) or PKA inhibitor (H 89 2HCl, 20 mg/kg) was administered intravenously via the tail vein (n = 10)...

BACKGROUND: Lipoprotein-associated phospholipase A2 activity (Lp-PLA2 -A) is a pivotal enzyme involved in the inflammatory process and atherosclerotic plaque vulnerability. This study aimed to investigate the potential of Lp-PLA2 -A as a biomarker for reflecting artery-to-artery embolism (AAE), a critical mechanism with high risk of stroke recurrence in symptomatic intracranial atherosclerotic disease (sICAD). METHODS: The current analysis included a cohort of 1,908 patients with sICAD and baseline levels of Lp-PLA2 -A from the Third China National Stroke Registry (CNSR-III)...

BACKGROUND: Carotid web is a thin shelf-like fibrointimal membrane arising from the posterior or posterolateral wall of the carotid bulb. Webs cause stroke, especially in younger adults with high risk of recurrence. METHODS: To report the first case of de-novo formation of an asymptomatic carotid web and describe longitudinal clinical-angiographic follow-up. RESULTS: A previously healthy 50-year-old White female presented with acute vestibular syndrome...

BACKGROUND: In the management of acute ischemic stroke with large vessel occlusion (LVO-AIS), current data are conflicting as to whether a mothership model of management (MS) is associated with better functional recovery than a drip-and-ship model (DS). METHOD: Files from LVO-AIS patients treated with MT at CHU Charleroi were analyzed between 01/01/2017 and 12/31/2022. Consecutive patients with a LVO-AIS of the anterior circulation and a prestroke modified Rankin Scale (mRS) ≤2 were included...

BACKGROUND: Inflammation is a potential mechanism underlying the development of white matter lesions (WMLs) and cerebral atrophy. We aimed to investigate the relationship of fibrinogen levels with WMLs and cerebral atrophy in patients with acute ischemic stroke (AIS). METHODS: A total of 701 AIS patients were enrolled. Participants were divided into four groups according to the quartiles of fibrinogen levels: Q1 < 2.58 g/L, Q2: 2.58-3.12 g/L, Q3: 3.12-3.67 g/L, Q4: ≥ 3...

BACKGROUND: The significant morbidity and mortality rates of acute intracerebral hemorrhage (ICH) are well-known around the world. The link between gut microbiota and different types of strokes is becoming more studied. The goal of this study was to look at the relationships between intestinal flora and early-stage mild-to-moderate ICH (emICH), and to provide a new perspective for adjunctive treatment of emICH. METHODS: Fecal samples from 100 participants with emICH (n=50) and healthy individuals (n=50) in this study were collected as well as analyzed utilizing 16S rRNA gene amplicon sequencing in order to characterize the gut microbial community...

OBJECTIVE: Increased arterial stiffness has been linked to aneurysm formation in the systemic and cerebral circulations, though the role played by arterial stiffness in the cerebral vasculature continues to be refined. This study assesses whether intraoperative surrogates of arterial stiffness differ between patients with cerebral aneurysms and controls, and the extend that these indices relate to outcomes following open surgical treatment. METHODS: We evaluated patients in a prospectively maintained database who underwent cerebral aneurysm surgery, and compare them to controls without cerebral aneurysms...

OBJECTIVE: While revascularization for M2 occlusions is generally recommended and considered beneficial, the optimal approach (aspiration vs stentriever/combined) is less well defined in the literature. We sought to compare outcomes after thrombectomy with manual aspiration thrombectomy alone (MAT) or stentriever-mediated aspiration thrombectomy (SMAT) MATERIALS AND METHODS: To circumvent inter-operator technical variability, patients underwent thrombectomy for M2 occlusions by a single operator and were stratified by first pass approach: manual aspiration thrombectomy (MAT/aspiration alone) and stentriever-mediated manual aspiration thrombectomy (SMAT/combination)...

OBJECTIVE: Some patients with acute minor stroke or transient ischemic attack (TIA) are at risk for a poor prognosis. There are a limited number of studies that have investigated the functional prognosis of acute mild ischemic stroke or TIA based on imaging indicators. This study aims to explore the relationship between Perfusion Variables and poor prognosis in patients with mild ischemic stroke or TIA. MATERIALS AND METHODS: A retrospective analysis was conducted on a cohort of 344 patients with mild ischemic stroke or TIA, who were admitted and treated at the First Affiliated Hospital of Soochow University between January 2016 and March 2022...

BACKGROUND: The efficacy and safety of endovascular thrombectomy (EVT) beyond 6 hours from stroke onset for patients with large vessel occlusion (LVO) selected without CT perfusion(CTP) or MR imaging(MRI) is undetermined. We conducted a systematic review and meta-analysis of the current literature comparing outcomes for late presenting patients with LVO treated by best medical management (BMM) with those selected for EVT based only on non-contrast CT(NCCT)/CT angiography(CTA) (without CTP or MRI)...

A 48-year-old man with no history of diagnosis with any abnormality was admitted to our hospital 43 min after onset of stroke. He had a right conjugate deviation and severe left hemiparesis, and his initial National Institutes of Health Stroke Scale (NIHSS) score was 13. Computed tomography (CT) of the head revealed no early ischemic changes, while CT angiography showed occlusion of the M1 proximal segment of the right middle cerebral artery. Intravenous thrombolysis was administered within 27 min of admission, and mechanical thrombectomy was performed...

OBJECTIVE: We report on the uncommon association between severe erythrodermic psoriasis and moyamoya angiopathy (MMA), a progressive cerebrovascular disorder characterized by steno-occlusive changes in the circle of Willis. Concomitant moyamoya and severe erythrodermic psoriasis is a rare pathology, with unknown pathogenesis. MMA with severe erythrodermic psoriasis, even in the setting of stroke, is often managed with non-curative medical intervention alone, due to concerns for surgical instability...

BACKGROUND: Cerebral collateral circulation plays a crucial role in determining the extent of brain ischemia in large vessel occlusive (LVO) stroke. Heart failure (HF) is known to cause cerebral hypoperfusion, yet the relationship between HF and robustness of collateral flow has not been well described. METHODS: Consecutive patients with middle cerebral and/or internal carotid LVO who underwent endovascular thrombectomy (EVT) between 2012 and 2020 were included...

BACKGROUND AND PURPOSE: Atherogenic index of plasma (AIP) is a newly identified as marker of lipid metabolism and glucose metabolism, showing significant predictive value in individuals with cardiovascular disease. This study aimed to explore the correlation between AIP and early neurological deterioration (END) in ischemic stroke patients after mechanical thrombectomy (MT). METHODS: Patients with anterior circulation large artery occlusive stroke who underwent MT were retrospectively enrolled from 2 stroke center in China...

BACKGROUND: The radiological pattern of stroke patients with thrombophilia is unknown. Our aim is to compare the MRI radiological pattern of silent and acute lesions in cryptogenic stroke/TIA patients under 60 years of age with and without thrombophilia. METHODS: Cryptogenic stroke/TIA patients under 60 years of age hospitalized at our Stroke Unit during four years were consecutively included. Thrombophilia screening was performed at 3 months after stroke and verified 12 weeks later...

BACKGROUND: Insulin Resistance (IR) is associated with stroke. This study aimed to investigate the correlation between metabolic score for insulin resistance (METS-IR) level, a new biomarker for assessing IR, and stroke.
