Assessment of Arterial Collateralization and Its Relevance to Intra-arterial Therapy for Acute Ischemic Stroke
Evidence from recent randomized controlled studies comparing intra-arterial (IA) therapy with intravenous tissue plasminogen activator highlighted the mismatch between recanalization success and clinical outcomes in patients presenting with acute ischemic stroke. There is emerging interest in the impact of arterial collateralization, as determined by leptomeningeal anastomoses (LMAs), on the treatment outcomes of IA therapy. The system of LMA constitutes the secondary network of cerebral collateral circulation apart from the Circle of Willis. Both anatomic and angiographic studies confirmed significant interindividual vari...

Relationship Between Magnetic Resonance Angiography–Diffusion-weighted Imaging Mismatch and Clinical Outcome in Endovascular Treatment for Acute Ischemic Stroke: Subgroup Analysis of the Recovery by Endovascular Salvage for Cerebral Ultra-acute Embolism–Japan Registry
Background: The presence or absence of the penumbra area is important when performing reperfusion therapy in patients with acute ischemic stroke. As a predictor of this penumbra area, magnetic resonance angiography (MRA)–diffusion-weighted imaging (DWI) mismatch is attracting attention. The usefulness of MRA–DWI mismatch (MDM) using the DWI–Alberta Stroke Program Early Computed Tomography Score (ASPECTS) in endovascular treatment (EVT) of patients with cerebral large vessel occlusion was evaluated.Methods: Of 1442 patients registered in the Recovery by Endovascular Salvage for Cerebral Ultra-acute Embolism–Japan Re...

Prediction of recanalization in acute stroke patients receiving intravenous and endovascular revascularization therapy
ConclusionThe overall likelihood of recanalization was the highest in the endovascular group, and higher for intravenous thrombolysis compared with no revascularization therapy. However, our statistical models of recanalization for each individual patient indicate significant variability between treatment options, suggesting the need to include this prediction in the personalized treatment selection.

Noncardiogenic Stroke Patients with Metabolic Syndrome Have More Border-zone Infarction and Intracranial Artery Stenosis
Little is known about the clinical character of stroke patients with metabolic syndrome (MetS) in Chinese population. In this hospital-based cross-sectional study, we elucidated the prevalence of MetS among patients with acute noncardiogenic cerebral infarction from south China, the topographic infarction patterns in magnetic resonance imaging, and vascular angiography findings of stroke patients with MetS.

Frequency of New Pulmonary Neoplasm Incidentally Detected by Computed Tomography Angiography in Acute Stroke Patients—A Single-Center Study
Incidental findings of suspect lung opacities are common in computed tomography (CT)–based thorax examinations, especially in high-risk patients, such as stroke patients. Screening with CT of the thorax has detected lung cancer in approximately .31%-1.20% of high-risk populations. The aim of the present study was to report the frequency of suspect lung opacities on routine acute stroke imaging.

A Case of Recurrent Ischemic Stroke Involving Subacute, Progressive Intracranial Cerebral Arterial Sclerosis Prior to Diagnosis with -mutated Polycythemia Vera
A 58-year-old man presenting with no vascular risk factors visited our hospital with right hemiparesis and total aphasia. Diffusion-weighted magnetic resonance imaging of the brain showed multiple hyperintensities in watershed distributions in the left hemisphere. Magnetic resonance angiography (MRA) revealed stenosis of the middle cerebral artery, despite normal MRA findings 2 months prior. One year after the first stroke, the patient experienced a recurrent ischemic stroke involving the left anterior choroidal artery, pulmonary embolism, and deep venous thrombosis.

Congenital Spinal Malformation and Stroke: Aneurysmal Dilatations and Bilateral Rotational Vertebral Artery Occlusion
A 30-year-old woman suffered from acute vertebrobasilar stroke. Cranial tomography (CT) scans showed multiple vertebral abnormalities suggestive of congenital spine malformation, and angiographic CT revealed aneurysmal dilatations (ADs) at segment V2 of both vertebral arteries (VAs). Dynamic neuroimaging tests including angiography and angio-CT were performed and showed occlusion of both VAs at the point of the ADs with contralateral rotation of the neck. The presence of a bony structure causing the artery compression was excluded and embolic phenomena originating at the AD was proposed as the likely source of stroke.

How temporal evolution of intracranial collaterals in acute stroke affects clinical outcomes
Conclusions: Not all collateral recruitment is beneficial; delayed collateral recruitment may be different from early recruitment and can result in worse outcomes and higher mortality. Prethrombolysis collateral status and recanalization are determinants of how intracranial collateral evolution affects functional outcomes.

Prevalences of Peripheral Arterial Disease Diagnosed by Computed Tomography Angiography in Patients with Acute Ischemic Stroke
Few studies have examined the prevalence of peripheral arterial disease (PAD) with the use of computed tomography angiography (CTA) in patients with acute ischemic stroke (AIS), although several reports have examined its prevalence using an ankle brachial index (ABI). We aimed to determine the prevalence of PAD indicated by CTA in patients with AIS and to clarify the prevalence of PAD in each clinical ischemic stroke subtype.
