Rationale: Bilateral thalamic infarction is a rare type of posterior circulation stroke, and it often presents with a reduced level of consciousness in the elderly. Arteriosclerosis is the primary etiology of bilateral thalamic infarction, including conditions such as native vessel stenosis or arterial-to-arterial embolism. Cardiogenic or paradoxical embolism can also lead to thrombosis of the perforator branches innervating the thalamus, and these emboli tend to disintegrate and lead to multiple lesions, even in elderly patients.

Background And Purpose: Identifying and assessing hemodynamic and flow status in patients with symptomatic internal carotid artery (ICA) occlusion is crucial for evaluating recurrent stroke risk. The aim of this study was to analyze the correlation between two quantitative imaging modalities: (1) blood oxygenation level-dependent (BOLD) cerebrovascular reactivity (CVR) and (2) quantitative magnetic resonance angiography (qMRA) with non-invasive optimal vessel analysis (NOVA), measuring volume flow rate (VFR). Comparing these modalities is relevant for assessing collateral circulation and hemodynamic impairment.

The most frequent of the embryonic persistent arteries that connect the internal carotid artery to the posterior circulation is the persistent primitive trigeminal artery (PPTA), which is recognized on 0.1%-0.6% on the basis of conventional angiography or magnetic resonance imaging (MRI).

Background And Aims: The clinical evolution of acute ischemic stroke patients with isolated proximal posterior cerebral artery (PCA) occlusion treated with medical management alone has been poorly described. We aimed to determine the clinical and radiological factors associated with poor functional outcome in this population.
Methods: We conducted a multicenter international retrospective study of consecutive stroke patients with isolated occlusion of the first (P1) or second (P2) segment of PCA admitted within 6hrs from symptoms onset in 26 stroke centers in France, Switzerland and the USA, treated with best medical management alone.

Background: The management of acute ischemic stroke due to isolated posterior cerebral artery occlusion (iPCAO) remains a topic of debate. This study investigates the efficacy and safety of endovascular treatment (EVT) versus best medical treatment (BMT) in patients with iPCAO.
Methods: A systematic search was conducted across electronic databases including PubMed, Embase, and the Cochrane Library.

Purpose: To develop an end-to-end DL model for automated classification of affected territory in DWI of stroke patients.
Materials And Methods: In this retrospective multicenter study, brain DWI studies from January 2017 to April 2020 from Center 1, from June 2020 to December 2020 from Center 2, and from November 2019 to April 2020 from Center 3 were included. Four radiologists labeled images into five classes: anterior cerebral artery (ACA), middle cerebral artery (MCA), posterior circulation (PC), and watershed (WS) regions, as well as normal images.

Persistent hypoglossal artery (PHA) is a rare, anatomical variant in which the posterior cerebral circulation is primarily supplied by a branch of the carotid artery, rather than the vertebral arteries. This case report discusses carotid endarterectomy performed on a man, 67 years of age, with high-grade, asymptomatic carotid artery stenosis and ipsilateral PHA. Preoperative computed tomography angiography identified the PHA arising from the internal carotid artery, compensating for atretic bilateral vertebral arteries and providing primary perfusion to anterior spinal artery.

Complication after carotid artery revascularization is mainly represented by stroke. Reversible cerebral vasoconstriction syndrome triggering by carotid artery revascularization is exceptional but it is an unrecognized aetiology of stroke. It could be associated with brain edema and henceforth, a posterior reversible encephalopathy syndrome can be confused with post-carotid artery revascularization cerebral hyperperfusion syndrome.

Background: Very limited data indicate that patients with stroke from cancer-associated NBTE (Ca-NBTE) exhibit a characteristic pattern of widely distributed ischemic lesions of varying sizes.
Methods: An electronic search of Mayo Clinic records (03/31/2002-06/30/2022) with ensuing manual review of brain magnetic resonance imaging (MRI) was performed to identify topographic characteristics of stroke from Ca-NBTE.
Results: In 112 patients with Ca-NBTE, 92 (82.
Introduction: Carotid endarterectomy (CEA) is a surgery aimed at removing atherosclerotic plaque from the carotid artery. There are classical and eversion CEA techniques. The eversion technique is the most popular because it does not require the use of implants.

To investigate the safety, efficacy and risk factors for complications of stenting with optional coiling versus coiling alone for acutely ruptured cerebral aneurysms (ARCAs) using different antiplatelet schemes, 2021 patients were prospectively enrolled into the stenting group (n = 967) and the coiling group (n = 1054). Four different antiplatelet regimens were used. The clinical and treatment data were analyzed and compared.

Objective: This study aims to explore the potential contribution of angiographic characteristics in the increased stroke risk among pediatric patients.
Methods: This study retrospectively enrolled pediatric patients with ischemic, hemorrhagic, and asymptomatic moyamoya disease. Their hemispheres were categorized into five groups for the analysis of angiographic characteristics, which included Suzuki's stage, moyamoya vessels, lenticulostriate artery, thalamotuberal artery, thalamoperforating artery, anterior choroidal arteries, posterior choroidal arteries, and posterior cerebral artery involvement.

Background: Endovascular thrombectomy (EVT) for very distal vessel occlusion (DVO) stroke is increasingly performed but there is insufficient evidence on the efficacy and safety of distal EVT techniques. We hypothesized that the technique of soft partial release of non-aggressive stent retrievers (SPORNS) reduces friction on the perforating vessels during thrombectomy and thereby reduces bleeding complications.
Methods: Retrospective study including consecutive DVO patients who were treated with the SPORNS technique between 1 January 2022 and 31 December 2022 at two tertiary stroke centers.

Carotid web, a form of fibromuscular dysplasia, involves a thin, membrane-like tissue in the carotid bulb that can cause thrombus formation and is linked to cryptogenic ischemic stroke. Diagnosis typically relies on detecting a shelf-like filling defect in digital subtraction angiography or 3D-CT angiography. We report a case of the symptomatic carotid web that could not be diagnosed using DSA or 3D-CT angiography due to a lodged thrombus but was successfully identified through carotid ultrasonography.

Background: Alexia without agraphia (AWA) is an acquired reading disturbance associated with left posterior cerebral artery (PCA) infarction. Based on autopsy and neuroimaging, there are two explanations for its pathogenesis: a visual cortex-language cortex disconnection and a visual word-form agnosia. Our goal was to discover if more refined brain imaging in a case-control study would provide further imaging support for either of these hypotheses.
