The Circulating Biomarker Fractalkine and Platelet-Derived Growth Factor BB are Correlated with Carotid Plaque Vulnerability Assessed by Computed Tomography Angiography
Ischemic cerebrovascular disease is a common and frequently occurring disease in neurology clinics world-wide, approximately 87% of all strokes are ischemic.1,2 Carotid artery stenosis is an independent risk factor for cerebral ischemic diseases.3 Presently, a stroke intervention in patients with carotid plaques depend mainly on the degree of stenosis.4 However, the risk of stroke related to carotid plaques is not only attributed to the flow-reduction from stenotic arteries, but also to the composition of atherosclerotic plaques.

Single-phase CT angiography predicts ASPECTS decay and may help determine when to repeat CT before thrombectomy
Time is relative in large-vessel occlusion acute ischemic stroke (LVO-AIS). We aimed to evaluate the rate of inter-hospital ASPECTS decay in patients transferred from a primary (PSC) to a comprehensive stroke center (CSC); and to identify patients that should repeat computed tomography (CT) before thrombectomy.

High-dose Argatroban Therapy for Stroke: Novel Treatment for Delayed Treatment and the Recanalization Mechanism
Conclusions: High-dose argatroban is an effective treatment for cerebral infarction and offers a novel therapeutic approach for delayed hospitalized patients at>24 hours after onset. Additional studies are necessary to identify the cellular and molecular mechanisms and determine the adequate dose in order to reduce risks of complication.

Emergent Angioplasty and Stent Placement Recanalization Without Thrombolysis in Acute Middle Cerebral Artery Occlusions
This study evaluated the feasibility, efficacy, and safety of intracranial artery recanalization for acute middle cerebral artery (MCA) occlusion using emergent angioplasty and stent placement without thrombolysis. All patients from a retrospectively collected database who met the inclusion criteria and were treated with an intracranial stent for acute MCA occlusion were included. Treatment comprised angioplasty and stenting without interventional thrombolytic therapy. Recanalization was assessed by angiography immediately after stent placement based on the Thrombolysis in Myocardial Infarction (TIMI) score. Complications ...

Additional Endovascular Therapy in Patients with Acute Ischemic Stroke Who Are Nonresponsive to Intravenous Tissue Plasminogen Activator: Usefulness of Magnetic Resonance Angiography–Diffusion Mismatch
Conclusions: AET for nonresponders to IV t-PA was safe, improved recanalization rates, and led to better prognoses. MDM was a very good predictor of improved prognosis in a selection of eligible patients for AET after IV t-PA.

Delayed Recurrent Stroke in a Young Patient with Acute Posterior Multifocal Placoid Pigment Epitheliopathy
We report a 15-year-old patient who had bilateral APMPPE, which was successfully treated with corticosteroids. One year later he presented with transient dysarthria and right hemiparesis. Brain magnetic resonance imaging (MRI) showed bilateral ischemic lesions in both lenticular nuclei and corona radiata. Brain MRI performed 3 months later revealed a new asymptomatic ischemic lesion. Cerebral angiography showed diffuse multifocal segmental vessel narrowing. The cerebrospinal fluid showed mononuclear pleocytosis in keeping with vasculitis. We started corticosteroid treatment, which lasted 10 months. Currently, after 2 years...

Recurrent Embolic Strokes Associated with Vertical Atlantoaxial Subluxation in a Patient with Rheumatoid Arthritis: A Case Report and Review of Literature
We report a 78-year-old woman with rheumatoid arthritis who developed recurrent embolic cerebellar strokes associated with vertical atlantoaxial subluxation (AAS). On contrast angiography, the bilateral vertebral arteries (VAs) were occluded between the C1 and C2 levels, and the distal parts of bilateral VA were supplied by the collateral circulations. Dynamic cerebral angiography and carotid duplex ultrasonography showed that blood flow was substantially decreased in the left VA and left posterior inferior cerebellar artery on cervical anteflexion. It is suggested that vertical AAS reduced the blood flow of collateral cir...

High-resolution Magnetic Resonance Imaging Reveals Hidden Etiologies of Symptomatic Vertebral Arterial Lesions
Conclusions: The application of HR-MRI in stroke patients with VA pathologies enabled the authors to determine the underlying pathophysiologies. These findings could be used to improve risk stratification and treatment decision making in symptomatic intracranial VA disease.

Current Utility of Diagnostic Catheter Cerebral Angiography
Conclusions: Our snapshot of 200 consecutive catheter cerebral angiograms shows that it is used for both primary diagnosis and surveillance in a wide variety of indications. Despite recent imaging trends, diagnostic catheter angiography provides clinically meaningful diagnostic information in enough cases to warrant continued use.

Moyamoya Disease Associated with Asymptomatic Mosaic Turner Syndrome: A Rare Cause of Hemorrhagic Stroke
We present the first reported case of an adult patient with previously unrecognized mosaic Turner syndrome with acute subarachnoid and intracerebral hemorrhage as the initial manifestation of moyamoya syndrome. A 52-year-old woman was admitted with a subarachnoid hemorrhage with associated flame-shaped intracerebral hemorrhage in the left frontal lobe. Physical examination revealed short stature, pectus excavatum, small fingers, micrognathia, and mild facial dysmorphism. Cerebral angiography showed features consistent with bilateral moyamoya disease, aberrant intrathoracic vessels, and an unruptured 4-mm right superior hyp...

Comparison of Carotid and Cerebrovascular Stenosis between Diabetic and Nondiabetic Patients Using Digital Subtraction Angiography
Conclusions: This retrospective study suggests that diabetes be associated with higher incidence of nonobstructive stenosis and that there be no significant difference observed in the extent and distribution of the extra- and intracranial artery stenoses between diabetic and nondiabetic patients.

Bilateral Medial Medullary Infarction with Nondominant Vertebral Artery Occlusion
Bilateral medial medullary infarction (MMI) is a rare stroke subtype. Here, we report a case with bilateral MMI caused by nondominant vertebral artery occlusion confirmed by brain digital subtraction angiography and magnetic resonance imaging basi-parallel-anatomical-scanning. We highlight that anterior spinal arteries could originate from a unilateral vertebral artery (VA). Radiologists and neurologists should pay attention to the nondominant VA as bilateral MMI may be induced by occlusion of nondominant VA that supplies the bilateral anteromedial territories of the medulla.
